Subject: [Openocd-development] ARM 1176
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.
