[OpenOCD-user] Ingenic T31

[Andrew W. <ts...@gm...>]

Wrongly posted in devel list originally...

This is a MIPS32 based embedded Linux device with UART pins multiplexed as
JTAG.
There is very little information provided by Ingenic on the use of these
pins as JTAG.
I would like to know if it is possible to get openocd working on this chip
if we can break out these pins.
Your docs say compatible with mips_4k.
Here is some info on our core.
Do you think it is possible to get openocd working here or is it a lost
cause?
