Hello all,
I'm trying to get Openocd + a wiggler interface working with an AU1100
MIPS based SOC. It seems the chip is recognized correctly (the JTAG
interface is working) but I can't access the memory. When I try to read
or write data the debug shows 'No memory access in progress!'. Anyone
has some suggestions on where to start looking? I've included the output
from OpenOCD below:
