It seems some issues in openocd-0.4.0 with MIPS 4KEc core, I did some
experiments below:
For info the MIPS has been mainly tested on a m4k (aka PIC32).
This also means that testing has been on a little endian system, so bugs
could be present.
Issue 1:
In telnet console, I set the breakpoint at 0x80000000, when I dump
memory in uboot, the SDBBP(software debug breakpoint) in memory is
0x3F000070 not 0x7000003F, so it's endian issue.
I modify src/target/mips32.h
line 138: #define MIPS32_SDBBP 0x7000003F ------> #define MIPS32_SDBBP
0x3F000070
then it's ok in uboot memory dump.
target_write_u32 should write to the target in the correct endian.
Cheers
