Good day.
I'm experimenting with openocd-2643 and imx31.
I'm trying to read/write to the onboard SRAM-buffer.
Discovered a strange behavior of openocd:
1. I write and read back the word:
> mww 0xb8000600 0x12345678
> mdw 0xb8000600 1
0xb8000600: 12345678
(it's OK)
2. I read a group of bytes:
> mdb 0xb80005f0 100
0xb80005f0: 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78
78 78 78 78 78 78 78 78 78 78
0xb8000610: 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78
78 78 78 78 78 78 78 78 78 78
0xb8000630: 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78
78 78 78 78 78 78 78 78 78 78
0xb8000650: 78 78 78 78
(This is wrong)
3. I write the word again:
> mww 0xb8000600 0x12345678
Data transfer failed. (1513377908)
Runtime error, file "command.c", line 473:
Question: Is there a way to avoid failure?
PS: memwrite burst disabled
Thank you.
