OpenOCD LPC2368 Flash Programming

Development Boards MicroMod
1

Has anyone been able to use the OpenOCD environment to program the flash in the LPC2368 processors?

I have tried the parport wiggler clone and the Olimex ARM-USB-OCD adapter with the Eclipse/OpenOCD environment. I can download and debug out of Ram as well as debug out flash using the Flashmagic tool to download the code. I have tried changing the flash bank speed setting and jtag_speed, as well as using rev1.15 and 1.30 but I still get the same results.

Hello ???,

try to use the new version of OpenOCD, r131 which can be found here:

http://www.yagarto.de/

Here a patch for the EmbeddedICE version 7 was added.

Best regards,

mifi

mifi,

Thanks for the quick reply. I have downloaded and tried the r131. And still get the results. Should I get the Warning: embeddedice.c:175 embeddedice_build_reg_cache(): EmbeddedICE version 7 detected, EmbeddedICE handling might be broken message? I don’t get it with the 115 revision.

Hi Craig,

this is a good question, but this was the part wich was added:

case 7:

WARNING(“EmbeddedICE version 7 detected, EmbeddedICE handling might be broken”);

reg_list[EICE_DBG_CTRL].size = 6;

reg_list[EICE_DBG_STAT].size = 5;

arm7_9->has_monitor_mode = 1;

break;

I think Dominic must handle this. But I could create a new version

if Dominic has a patch. This is no problem.

Regards,

Michael

Hi Michael,

It appears that if I do the commands through telnet they work, but using the Eclipse/GDB I get the errors mentioned earlier.

Telnet:

telnet> halt

telnet>flash erase 0 0 26

telnet>flash write 0 myfile.bin 0

Eclipse Debug

target remote localhost:3333

monitor halt

monitor flash erase 0 0 26

monitor flash write 0 myfile.bin 0

Best Regards,

Craig

Hello,

the “Warning:” about EmbeddedICE version 7 is intentional - I couldn’t find any documentation for this new version, and therefor don’t know about possible sideeffects.

I’m not sure about the reason for the errors you see when trying to programm from within Eclipse. I’ll see if I can reproduce this problem.

Regards,

Dominic
