Hi, I would like to test my -rt kernels releases on the minnowboard. Though cyclictest always reports 2 to 4 ms spikes. It looks like that the original firmware is stealing those cycles. So my plan was to try out coreboot and see if my theory is correct or not.
Now, I am struggling with getting anything working. All my attempts to bake a working binary have been completely fruitless. Not a single char on the serial port. If I would at least get something on the serial port I could find my way through the maze. I am confident that flashing the device is works correctly via my raspberry pi [2]. When I flash the original firmware, the device comes back to live again. Unfortunately, the documentation on how to configure and build coreboot a bit outdated [1]. My google-foo didn't help either. Could someone share his/her current config and also post the SHAs of coreboot? This would rule out that part. I am not sure if my binary blobs I extracted or downloaded are okay (fd, me, gbe, FSB).
