Yes, the LPC2106 User Manual states that the 'unlock' command will
allow the boot block to be overwritten.

Still, Philips has released the program "LPC2000 Boot Loader update
via ISP" that somehow modifies the similarly unmodifiable boot
sectors of the devices prior to LPC213x...

I have ported some samples for the MBC2130 and GCC that I can send you
if you like. No FreeRTOS yet I'm affraid.
The samples I ported is the
blink_switch
blink_switch_irq
ds18s20 (some bugs fixed also in the 1-wire code which is now more stable.)
uart0
uart0_irq
Cheers

Well I've got the MCB2130 talking to the Philips flash utility. Now
I'm
not sure why?
The only thing I can thing of is that I've rebooted the PC? how
frustrating.
Regardless, thanks for all the help.
Now on to the real problem.
I'm trying to get FreeRTOS running on the LPC2138.
I can use the Keil demo compiler to compile the Keil demo to work.
I've managed to get the 2016 GCC demo compiled and downloaded to the
board. Of course it doesn't work. :-)
I'm new to the ARM LPC2138, GCC and FreeRTOS, so it is a steep learning
curve.
The LPC2016 GCC FreeRTOS demo is targeted at the Olimex board.
Can anyone point me to a demo targeted at the LPC2138 or at least point
me in the right direction to configure RTOS for the LPC2138.
Once again that for the help with the flashing problem.
Cheers,
Peter.

There's a bit of a discussion in the User Manual - in fact, I
thought it was quite complete although I haven't tried to use it to
implement a downloader.

Hi,
Thanks guys. I'll break out the test gear tonight.
From what is being said, it is either a hardware problem, or the LPC is
not entering boot mode.
I can hold P0.14 lo, then use a terminal program to issue '?' and see
if
there is a response.
Do you know what the rest of the command set is?, or will the '?'
character cause the boot loader to spit it out at me?
Cheers,
Peter.

I read all around that paragraph. But that's the word - it can't be
overwritten.

Please refer to the Philips manual: "LPC213x User Manual" #UM10120,
top
of page 221.

We need Philips to weigh in on this. I noticed from the User Manual
that IAP is prevented from overwriting the boot loader and I would
expect the loader to protect itself when doing ISP.
Anything is possible but I would look around a little more before I
worried about the loader. For example, are you certain that P0.14
is actally pulled low during reset? I would look at it with a scope
or logic probe (LED if I had to) just to be certain something else
wasn't happening.
I would certainly look at the check box in the lower right corner of
the Flash Utility window and make sure it was checked - Use DTR/RTS
for Reset and Boot Loader Selection. Certainly answers my dumb
question! I'll incorporate this concept when I design my board.

Richard,
Yes, it had been working. I think I downloaded a Hex file for a
processor other than the LPC2138 and then it seemed to stop working.
I don't think it is a hardware problem.
For the third time, is it possible to erase the boot loader or screw it up?
Cheers,
Peter.
