I am almost certain that the RAM memory is not initialized correctly. I wrote a simple RAM test function which writes some pattern data into 0x0 - 0x400 address range and then reads it. The difference occurs already at the first cell. There is 0x00, but should be 0xFF. Conclusion is that RAM initialization for adl/msm800sev target is not valid. -- Piotr Piwko http://www.embedded-engineering.pl/ -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
