Hello,
I have recenently bought the olimex arm-usb-ocd. I have installed the
software that is provided, This includes eclipse, gnu arm tool set
and the FDTI drivers for the debugger.
I have successfully managed to debug the sample code that is provide
with the software. This is the code that is part James Lycnh's
excellent tutorial.
However, I would like to move onto something a little meatier, and
decided to start playing around with freeRTOS. I can compile freeRTOS
with no issues, however when I try to download the code into a olimex
2106 prototype board it doesn't work. I get the following text from
the eclipse console:
(gdb) target state: halted
target halted in Thumb state due to debug request, current mode:
Supervisor
cpsr: 0x800000f3 pc: 0x7fffe24c
flash 'lpc2000' found at 0x00000000
erased sectors 0 through 0 on flash bank 0 in 0s 453125us
wrote file main.bin to flash bank 0 at offset 0x00000000 in 0s
171875us
requesting target halt and executing a soft reset
force hardware breakpoints enabled
Eclipse then seems to go into a state where says its launching, but
never actually gets past the 10% stage and doesn't break in main.
I have tried both the ROM and RAM versions and I get the same result
both times.
I have noticed a difference in the output extensions of the simple
projects that work and freeRtos which isnt working for me.
The simeple project generate a file called main.out. Where as
freeRTOS generates rtosDemo.elf. Is this the problem?
Any help would be appreciated.
Regards
Iain

One reason why the program doesn't work is because you are deleting only
the 1st sector.
Change the following line in your configuration file:
flash erase 0 0 0
to:
flash erase 0 0 'x'
where 'x' is the number of the last sector you want to delete.

Hello Iain,
please use a current version of the OpenOCD, not the one that came with your
ARM-USB-OCD. You can find precompiled binaries at www.yagarto.de.
Best regards,
Dominic

Hello Dominic,
I have downloaded the latest version of OpenOCD.
After trying again I have realised that debugging does work when running in RAM (for both simple examples and freeRTOS), but not when I try and download into flash. Im sure i tried in both RAM and ROM before and neither worked.
Do you have any other suggestions?
I am new to gcc, gdb, eclipse and LPC micros, so it maybe something ridiculously silly, Im just not seeing it.
Regards
Iain
