Re: [coreboot] microcode blob or ascii

[Jose Trujillo]

Sorry,
I cannot help you with this.... maybe I still don't understand.

The only thing I can tell you that I use for this same SOC processor all the header files ".h" included in the kit and they work without problems.
It would be good if you can enable the serial debug console and dump the log if you have problems.

Good luck,
Jose.
