Hi Alex,
I tested the latest Git kernel on my FSL P5040 board today and it
doesn't boot. Our FSL P5020 boards boot without any problems.
I connected my FSL P5040 board with a serial cable to my PC for
getting error messages. Unfortunately there aren't any error messages
after the loading of the uImage.
This means, that the dma-mapping patch doesn't solve the boot issue.
Please check the latest DRM updates.
Can you bisect the problem ?
Christophe
I would like ... but I don't have time for it. Sorry.
