[Openocd-development] MIPS and Big Endian

Hi all, I just tried to load a small test ELF like this : 80008000 _ftext: 80008000: 3c088001lui t0,0x8001 80008004: 8d089014lw t0,-28652(t0) 80008008: 24090005li t1,5 8000800c: 3c018001lui at,0x8001 80008010:

Hi all, this seems to be OpenOCD endianess probelem for MIPS big endian targets. This is what I concluded with further instigation. I started target in little endian mode and let it configure SDRAM. In this case SDRAM is well configured, all values well written and load to SDRAM works correctly.

Even further investigation of the problem lead to these posts : http://www.mail-archive.com/openocd-development@lists.berlios.de/msg05586.html Can anybody tell me if the patch David proposed is well applied ? Although there are some traces of Davids changes in the mips_ejtag.c file, I can not see

Hi all, embedding David's solutions for mips_m4k_write_memory() and mips_m4k_read_memory() from commit b271efe12132e93cb17adb037323f6cf251305b2 seems to be solving the problem for the small files. However, trying to load a bigger image function mips_m4k_bulk_write_memory() is called an fails in

Hello list, about two weeks ago I spent a few days at Embedded World exhibition in Nuremberg where we had a tiny booth for Hochschule Augsburg (this is where OpenOCD started years ago with Dominic's thesis). We exhibited some student projects, despite OpenOCD was not in the main focus, we had

[Openocd-development] [PATCH] Fix a bunch of typos.

Fix a bunch of typos. Most are in code comments, so nothing should break. UNKOWN_COMMAND and CMD_UNKOWN are not used elsewhere, so correcting the spelling should also not break anything. --- src/flash/nand/mx2.c |2 +- src/flash/nand/mx3.c |2 +- src/flash/nor/at91sam3.c
