Flash Programming via JTAG with PP Wiggler?

Development Boards MicroMod
1

Greetings All:

It seems I can now do everything with my PP wiggler except program the FLASH. I can program RAM, debug code executing within RAM and debug code loaded with the Philips utility into FLASH.

However when I try to load the flash via OpenOCD-pp version r141 I find the process locks up into a forever loop. OpenOCD-pp seems to start OK with the usual warning message and then nothing further happens except status bar indicates progress of 0% build. My associated make file lines, console output, script and pp config files are below.

Many thanks in advance for any suggestions!

Here is some additional information:

  • the target MPU is the LPC2103 with 32K Flash and 8K RAM.

  • I have placed the script file in the OpenOCD\bin directory and also in the target program development work space directory.

  • The pgm_mem.bin file is also located in the target program development work space directory.

  • I set the Build Make Target Eclipse command options according to Jim Lynch’s excellent Cross Devlopment tutorial.

I hope this provides more clues…

I would try to execute the commands in lpc2103JTAGpgm.script one by one from the OpenOCD telnet interface to see where in the script things go wrong.

When you have found that you can get more detailed information by setting

debug_level 3

Hi Magnus:

Many thanks for your suggestion. I didn’t think of trying to access OpenOCD via Telnet…I didn’t know until now that there is a whole ASCII command set. This is a very nice testing method to know about!!!

I have concluded the problem I have is that OpenOCD-pp.exe is not opening the script file. I am going to post more questions under a different subject title.

Thanks Again for the Tip!

I have the same problem with an LPC-E2294 board and the USB OCD Tiny. Have you been able to find a solution?

Greetings:

I finally gave up trying to program FLASH with my parallel port wiggler. I decided to buy an Olimex ARM-USB-OCD and installed their GCC tool chain distribution. It runs under Cygwin and so far has been working great for programming FLASH.

I think I am close to reaching the productive stage with GNUARM and remain hopeful that the time spent learning this development system will ultimately prove to have been a worthwhile effort.
