[OpenOCD-user] Why 0xb8050000 address in ar71xx.cfg when 0x1805000 is correct

[Salvador A. f. <sar...@ya...>]

The core only works with virtual addresses. Please check the state of 
the error level bit (ERL bit in Status register) and reread in the docs 
the implications of this bit in the memory mapping regarding useg/Kuseg.
The Status register is saved and restored by openocd when enters/exits debug mode.
"reg status" or "mips32 cp0 12 0" can be used to read/modify this bit 
(bit 2). Modifications with "reg status" only takes effect when leaving debug mode.
Hopefully this is enough to do some tests and answer yourself some questions.
I'll send later a more detailed explanation regarding openocd implications.
Thanks,
Salvador.
