Hi
My program runs fine when booting using my wiggler but when I remove
the wiggler and reboot the program won't run or it might be in an
interrupt routine or something, I can't check without the wiggler. Do
you have to do anything with your program in order for it to run
without the wiggler? Can anyone help me?

The processor is the LPC2294 on an Olimex development board. I use the
CAN-interface and the UART0.

Best Regards
David Berg

booting means you just issue an reset with the wiggler ?
Or do you run any setup file ?

Try some printf debugging to see which parts are excecuted.

Hello,

are logic level of all JTAG signals correct according to users manual (all neccessary pull-up and
pull-down resistors) if no wiggler is connected? (DBGSEL, RTCK, TCK, ...)
Could it be that JTAG engine is blocking due to bad signals?

When I wrote booting I meant that i did a reset on the board with
the wiggler physically removed. I have tried resetting the board
without the wiggler earlier without problems but that was a couple
of months ago and my program has evolved quite alot since.

Sten >>

I'm not sure about all JTAG signals but I have been able to run
programs on the board without the wiggler a couple of months ago.
The only jumper I remember changing when removeing the wiggler is
the DBG jumper. It's connected to RTCK.

Hi,

do you just connect your Wiggler, or are you running the OpenOCD, too, when
your program fails?

Dominic

When the program works I have the wiggler connected to the board and
the OpenOCD-program running so that I can step through my code in
eclipse and everything works fine.

When it doesn't work I don't have the wiggler connected and
naturally I don't have the OpenOCD program running either.

Best Regards

Okay, so what exactly are you doing when
> My program runs fine when booting using my wiggler

Do you reset your system using the boards reset switch?
If you're using the OpenOCD to reset the board, what reset type do you use,
reset_run? run_and_halt? run_and_init?
Maybe you're using an init script to initialize parts of your chip?

Regards,

Dominic

When I boot without the wiggler i disconnect the USB-cable that
powers the board and then reconnect it. After that I have also tried
the RST-button on the board. When I use the wiggler I first
disconnect/connect the USB-cable. This is my commands issued to gdb:

target remote localhost:3333
monitor reset
monitor sleep 500
monitor poll
monitor soft_reset_halt
break main
monitor arm7_9 force_hw_bkpts enable
continue

And here's the configuration script to OpenOCD (taken from the
winarm distribution):

#daemon configuration
telnet_port 4444
gdb_port 3333

#interface
interface parport
parport_port 0x378

Is the checksum in the exception vector area set correctly?

I have no idea. Is that something I have to set myself? Where/how do
I do that?

Now I've been able to first start the program up with the wiggler
then removeing the wiggler from tha board and pressing the RST-
button. And the program works when i use the RST-button but as soon
as I disconnect the USB and reconnects it it stops working until I
once again connect the Wiggler and resets the board through
gdb/wiggler.

I've now looked at some output from GDB in Eclipse:

target remote localhost:3333
(gdb) UNDEF_Routine () at main.c:1637
1637 while (1) ;
(gdb) monitor reset
(gdb) monitor poll
target state: halted
target halted in ARM state due to debug request, current mode: Abort
cpsr: 0x90000097 pc: 0x000020b0
(gdb) monitor soft_reset_halt
requesting target halt and executing a soft reset
(gdb) monitor arm7_9 force_hw_bkpts enable
force hardware breakpoints enabled
(gdb) continue

Breakpoint 1, main () at main.c:230
230 lpc229x_system_init();
(gdb)

It seems like the program is stuck in an ISR for Undefined
Instruction Mode before the monitor reset command is issued... But
why doesn't the program end up in that routine again after the
reset? Very strange

In that case you are likely stuck in ISP mode. All the serial download
programs calculate and insert this automatically, I don't believe the JTAG
ones do.

Check the user manual to find the address of the exception vector used for
the checksum and see what it's set to after you program.

I seem to recall someone mentioning that the philips download utility would
allow you to load a hex file, calculate the checksum and write it back out
but I wouldn't swear to it.

Sum up the first 8 longs, the result must be zero.

Ok, I think I haven't been clear on one thing: My program are run
from flash and I download it to the board using Phillips Flash
Utility through USB/Serial. I don't download a different or new
program when using the wiggler or not using the wiggler, I just
disconnect it or reconnects it, the program in flash never changes.
