[Openocd-development] ARM 1176

[Austin, A. <Ale...@sp...>]

I know ARM11 support is incomplete, but I was hoping to be able to read/write flash.

What does the IR capture error indicate?
What does SCREG OUT 0x00 mean?
Is the openocd scan still reading the IDCODE wrong? I do know that it is an ARM1176.
