Re: about PLL of LPC2378 - Cool Dude - Nov 7 0:03:58 2008
Which IDE are you using. Since your code is not working I suggest you to to=
test your code little by little.. I would like you to see if your PLL conf=
iguration works properly by displaying a single LED because high end LPC's =
have a different a configuration for PLL than lower end LPC's. Chances of m=
aking mistakes would be high. Comment out MAM and LCD's and include them la=
ter if you feel what you have done is right

Olimex LPC-E2468 JTAG Debug - Bruce Paterson - Nov 7 1:45:42 2008
Hi all,
I'm having real problems getting debugging going with the Olimex
LPC-E2468 card (PC host) and after one of those frustrating sorts of
days I'm looking for some pointers where to go next.
History:
I've been using Eclipse with Openocd and an Amontec JTAGKey for some
years now with various LPC2138 and LPC2148 custom targets, and after
some initial problems have largely been happy with the setup. (An
Amontec died at one stage and had to buy another, but suspect static
damage).
I stayed with the 2006 version of openocd I had at the time as it worked
OK.
Now:
Trying to get a couple of lpc2468 Olimex cards going (prior to custom),
but it hasn't been clear sailing, and I'm not quite sure why !
At the same time bought a couple of Olimex ARM-USB-OCD debug dongles to
supplement the Amontec due to the number of new projects.
What works:
The old "2006 openocd", JTAGKey and LPC2148 custom target: Obviously,
that's what I've been using.
The brand new 717 2008 openocd off Yagarto site, JTAGKey and LPC2148
works also (more info messages etc than before)
What doesn't work:
The "2007 openocd", JTAGKey and LPC2148. That openocd comes with Olimex
CDs. (Just note this one in passing).
717 openocd, JTAGKey and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-2148 card that works above (debug
below).
Old 2006 openocd, JTAGKey and LPC-E2468 (I tried everything!).
In summary:
JTAGKey can work with 2148 but not E2468
ARM-USB-OCD works with neither.
I must be doing something very wrong !
It seems where the *.cfg files live in the openocd tree has changed for
the different openocd versions, but assume I've picked the appropriate
one for the particular JTAG USB dongle in each case.
I have 2 LPC-E2468 cards. One still has the supplied Linux/U-boot etc on
board, the other has our custom hex file programmed via FlashMagic and
the FT232 Uart on card. Since I don't get openocd to start successfully
this may not be relevant. I sometimes get different debug output
depending on whether I power the card or the dongle first.
Debug from Eclipse console:

starting gdb useless. No idea what is different this time from last time
really.

So,
Is the JTAG on a 2148 and 2468 processor identical ? (ie. If it works
for 2148 it should for 2468 ?)
It is something to do with SRST and TRST timing / relationship ?
Has anyone got a JTAGKey or an ARM-USB-OCD working with an Olimex

------------------------------------
(You need to be a member of lpc2000 -- send a blank email to lpc2000-subscribe@yahoogroups.com )
I'm having real problems getting debugging going with the Olimex
LPC-E2468 card (PC host) and after one of those frustrating sorts of
days I'm looking for some pointers where to go next.
History:
I've been using Eclipse with Openocd and an Amontec JTAGKey for some
years now with various LPC2138 and LPC2148 custom targets, and after
some initial problems have largely been happy with the setup. (An
Amontec died at one stage and had to buy another, but suspect static
damage).
I stayed with the 2006 version of openocd I had at the time as it worked
OK.
Now:
Trying to get a couple of lpc2468 Olimex cards going (prior to custom),
but it hasn't been clear sailing, and I'm not quite sure why !
At the same time bought a couple of Olimex ARM-USB-OCD debug dongles to
supplement the Amontec due to the number of new projects.
What works:
The old "2006 openocd", JTAGKey and LPC2148 custom target: Obviously,
that's what I've been using.
The brand new 717 2008 openocd off Yagarto site, JTAGKey and LPC2148
works also (more info messages etc than before)
What doesn't work:
The "2007 openocd", JTAGKey and LPC2148. That openocd comes with Olimex
CDs. (Just note this one in passing).
717 openocd, JTAGKey and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-2148 card that works above (debug
below).
Old 2006 openocd, JTAGKey and LPC-E2468 (I tried everything!).
In summary:
JTAGKey can work with 2148 but not E2468
ARM-USB-OCD works with neither.
I must be doing something very wrong !
It seems where the *.cfg files live in the openocd tree has changed for
the different openocd versions, but assume I've picked the appropriate
one for the particular JTAG USB dongle in each case.
I have 2 LPC-E2468 cards. One still has the supplied Linux/U-boot etc on
board, the other has our custom hex file programmed via FlashMagic and
the FT232 Uart on card. Since I don't get openocd to start successfully
this may not be relevant. I sometimes get different debug output
depending on whether I power the card or the dongle first.

RE: Olimex LPC-E2468 JTAG Debug: Update - Bruce Paterson - Nov 9 22:59:54 2008
No success yet, but an update.
Any suggestions welcome !
Olimex LPC-E2468:
The R76 value was 100 Ohms, not 100kOhms as shown on the circuit. This
is the RTCLK pullup resister. Not certain if this a show-stopper or not
because still not working, but it certainly wouldn't help !
Anyone else got a LPC-E2468 board they can check to see if 100 Ohms
("101") or whether this was a load error on the oards we've bought ?
Amontec JTAGKey:
* I am able to use the 717 openocd with my original lpc-2148 board as
long as I comment out the 2 "jtag_reset" lines in the config script
lpc2xxx_jtagkey.cfg. The original version of the config file didn't have
these lines. Why ?
* The JTAGKey gets confused if you have *another* FT232 device on the
system, such as the serial port on the LPC-E2468 board ! It finds that
device before finding itself and latches onto that. Only a computer
reboot will kill off openocd in this case. I switched to external
powering on LPC-E2468 when attempting to use the JTAGKey.
* Unfortunately it seems openocd is still unable to "halt" the processor
on the LPC-E2468 card, so it can't really get anywhere.
Cheers,
Bruce

Subject: [lpc2000] Olimex LPC-E2468 JTAG Debug
Hi all,
I'm having real problems getting debugging going with the Olimex
LPC-E2468 card (PC host) and after one of those frustrating sorts of
days I'm looking for some pointers where to go next.
History:
I've been using Eclipse with Openocd and an Amontec JTAGKey for some
years now with various LPC2138 and LPC2148 custom targets, and after
some initial problems have largely been happy with the setup. (An
Amontec died at one stage and had to buy another, but suspect static
damage).
I stayed with the 2006 version of openocd I had at the time as it worked
OK.
Now:
Trying to get a couple of lpc2468 Olimex cards going (prior to custom),
but it hasn't been clear sailing, and I'm not quite sure why !
At the same time bought a couple of Olimex ARM-USB-OCD debug dongles to
supplement the Amontec due to the number of new projects.
What works:
The old "2006 openocd", JTAGKey and LPC2148 custom target: Obviously,
that's what I've been using.
The brand new 717 2008 openocd off Yagarto site, JTAGKey and LPC2148
works also (more info messages etc than before)
What doesn't work:
The "2007 openocd", JTAGKey and LPC2148. That openocd comes with Olimex
CDs. (Just note this one in passing).
717 openocd, JTAGKey and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-2148 card that works above (debug
below).
Old 2006 openocd, JTAGKey and LPC-E2468 (I tried everything!).
In summary:
JTAGKey can work with 2148 but not E2468
ARM-USB-OCD works with neither.
I must be doing something very wrong !
It seems where the *.cfg files live in the openocd tree has changed for
the different openocd versions, but assume I've picked the appropriate
one for the particular JTAG USB dongle in each case.
I have 2 LPC-E2468 cards. One still has the supplied Linux/U-boot etc on
board, the other has our custom hex file programmed via FlashMagic and
the FT232 Uart on card. Since I don't get openocd to start successfully
this may not be relevant. I sometimes get different debug output
depending on whether I power the card or the dongle first.
Debug from Eclipse console:

So,
Is the JTAG on a 2148 and 2468 processor identical ? (ie. If it works
for 2148 it should for 2468 ?)
It is something to do with SRST and TRST timing / relationship ?
Has anyone got a JTAGKey or an ARM-USB-OCD working with an Olimex
LPC-E2468 card ? Need to add an extra pullup/pulldown somewhere maybe ?
A bit Frustrated,
Bruce

Any suggestions welcome !
Olimex LPC-E2468:
The R76 value was 100 Ohms, not 100kOhms as shown on the circuit. This
is the RTCLK pullup resister. Not certain if this a show-stopper or not
because still not working, but it certainly wouldn't help !
Anyone else got a LPC-E2468 board they can check to see if 100 Ohms
("101") or whether this was a load error on the oards we've bought ?
Amontec JTAGKey:
* I am able to use the 717 openocd with my original lpc-2148 board as
long as I comment out the 2 "jtag_reset" lines in the config script
lpc2xxx_jtagkey.cfg. The original version of the config file didn't have
these lines. Why ?
* The JTAGKey gets confused if you have *another* FT232 device on the
system, such as the serial port on the LPC-E2468 board ! It finds that
device before finding itself and latches onto that. Only a computer
reboot will kill off openocd in this case. I switched to external
powering on LPC-E2468 when attempting to use the JTAGKey.
* Unfortunately it seems openocd is still unable to "halt" the processor
on the LPC-E2468 card, so it can't really get anywhere.
Cheers,
Bruce

Subject: [lpc2000] Olimex LPC-E2468 JTAG Debug
Hi all,
I'm having real problems getting debugging going with the Olimex
LPC-E2468 card (PC host) and after one of those frustrating sorts of
days I'm looking for some pointers where to go next.
History:
I've been using Eclipse with Openocd and an Amontec JTAGKey for some
years now with various LPC2138 and LPC2148 custom targets, and after
some initial problems have largely been happy with the setup. (An
Amontec died at one stage and had to buy another, but suspect static
damage).
I stayed with the 2006 version of openocd I had at the time as it worked
OK.
Now:
Trying to get a couple of lpc2468 Olimex cards going (prior to custom),
but it hasn't been clear sailing, and I'm not quite sure why !
At the same time bought a couple of Olimex ARM-USB-OCD debug dongles to
supplement the Amontec due to the number of new projects.
What works:
The old "2006 openocd", JTAGKey and LPC2148 custom target: Obviously,
that's what I've been using.
The brand new 717 2008 openocd off Yagarto site, JTAGKey and LPC2148
works also (more info messages etc than before)
What doesn't work:
The "2007 openocd", JTAGKey and LPC2148. That openocd comes with Olimex
CDs. (Just note this one in passing).
717 openocd, JTAGKey and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-2148 card that works above (debug
below).
Old 2006 openocd, JTAGKey and LPC-E2468 (I tried everything!).
In summary:
JTAGKey can work with 2148 but not E2468
ARM-USB-OCD works with neither.
I must be doing something very wrong !
It seems where the *.cfg files live in the openocd tree has changed for
the different openocd versions, but assume I've picked the appropriate
one for the particular JTAG USB dongle in each case.
I have 2 LPC-E2468 cards. One still has the supplied Linux/U-boot etc on
board, the other has our custom hex file programmed via FlashMagic and
the FT232 Uart on card. Since I don't get openocd to start successfully
this may not be relevant. I sometimes get different debug output
depending on whether I power the card or the dongle first.

So,
Is the JTAG on a 2148 and 2468 processor identical ? (ie. If it works
for 2148 it should for 2468 ?)
It is something to do with SRST and TRST timing / relationship ?
Has anyone got a JTAGKey or an ARM-USB-OCD working with an Olimex
LPC-E2468 card ? Need to add an extra pullup/pulldown somewhere maybe ?
A bit Frustrated,

RE: Olimex LPC-E2468 JTAG Debug: Update - Bruce Paterson - Nov 10 2:00:33 2008
To continue my monologue, in case anyone is interested :)
I now have debugging working somewhat on the LPC-E2468 board, both with
the JTAGKey and the ARM-USB-OCD dongles.
The reason for the problem (other than the 2 things noted earlier
below), was my program on card 1 was going off into the weeds (TBD why)
and disabling JTAG. [Discovered by switching JTAG to boundary scan using
the DBGSEL pin and openocd could see it, but not the uP JTAG...ahha!].
I thought I'd eliminated this possibility on card 2 by leaving it with
original Olimex supplied code, but alas this must also affect the JTAG
pins. Grrr my bad.
Still can't get the ARM-USB-OCD working on the lpc-2148 original card.
Openocd throws up all sorts of problems. JTAGKey works fine. Of course I
tried commenting out the "jtag-reset" lines in the armusbocd.cfg file as
well (see below) but it didn't help. It'd be nice to know why it doesn't
work, but not as immediately critical.
Cheers,
Bruce

Subject: RE: [lpc2000] Olimex LPC-E2468 JTAG Debug: Update
No success yet, but an update.
Any suggestions welcome !
Olimex LPC-E2468:
The R76 value was 100 Ohms, not 100kOhms as shown on the circuit. This
is the RTCLK pullup resister. Not certain if this a show-stopper or not
because still not working, but it certainly wouldn't help !
Anyone else got a LPC-E2468 board they can check to see if 100 Ohms
("101") or whether this was a load error on the oards we've bought ?
Amontec JTAGKey:
* I am able to use the 717 openocd with my original lpc-2148 board as
long as I comment out the 2 "jtag_reset" lines in the config script
lpc2xxx_jtagkey.cfg. The original version of the config file didn't have
these lines. Why ?
* The JTAGKey gets confused if you have *another* FT232 device on the
system, such as the serial port on the LPC-E2468 board ! It finds that
device before finding itself and latches onto that. Only a computer
reboot will kill off openocd in this case. I switched to external
powering on LPC-E2468 when attempting to use the JTAGKey.
* Unfortunately it seems openocd is still unable to "halt" the processor
on the LPC-E2468 card, so it can't really get anywhere.
Cheers,
Bruce

Subject: [lpc2000] Olimex LPC-E2468 JTAG Debug
Hi all,
I'm having real problems getting debugging going with the Olimex
LPC-E2468 card (PC host) and after one of those frustrating sorts of
days I'm looking for some pointers where to go next.
History:
I've been using Eclipse with Openocd and an Amontec JTAGKey for some
years now with various LPC2138 and LPC2148 custom targets, and after
some initial problems have largely been happy with the setup. (An
Amontec died at one stage and had to buy another, but suspect static
damage).
I stayed with the 2006 version of openocd I had at the time as it worked
OK.
Now:
Trying to get a couple of lpc2468 Olimex cards going (prior to custom),
but it hasn't been clear sailing, and I'm not quite sure why !
At the same time bought a couple of Olimex ARM-USB-OCD debug dongles to
supplement the Amontec due to the number of new projects.
What works:
The old "2006 openocd", JTAGKey and LPC2148 custom target: Obviously,
that's what I've been using.
The brand new 717 2008 openocd off Yagarto site, JTAGKey and LPC2148
works also (more info messages etc than before)
What doesn't work:
The "2007 openocd", JTAGKey and LPC2148. That openocd comes with Olimex
CDs. (Just note this one in passing).
717 openocd, JTAGKey and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-E2468 card (debug below).
717 openocd, ARM-USB-OCD and LPC-2148 card that works above (debug
below).
Old 2006 openocd, JTAGKey and LPC-E2468 (I tried everything!).
In summary:
JTAGKey can work with 2148 but not E2468
ARM-USB-OCD works with neither.
I must be doing something very wrong !
It seems where the *.cfg files live in the openocd tree has changed for
the different openocd versions, but assume I've picked the appropriate
one for the particular JTAG USB dongle in each case.
I have 2 LPC-E2468 cards. One still has the supplied Linux/U-boot etc on
board, the other has our custom hex file programmed via FlashMagic and
the FT232 Uart on card. Since I don't get openocd to start successfully
this may not be relevant. I sometimes get different debug output
depending on whether I power the card or the dongle first.

^^^^
Looks like it *nearly* gets there this time, but still can't halt =>
starting gdb useless. No idea what is different this time from last time
really.

So,
Is the JTAG on a 2148 and 2468 processor identical ? (ie. If it works
for 2148 it should for 2468 ?)
It is something to do with SRST and TRST timing / relationship ?
Has anyone got a JTAGKey or an ARM-USB-OCD working with an Olimex
LPC-E2468 card ? Need to add an extra pullup/pulldown somewhere maybe ?
A bit Frustrated,
Bruce
