I am trying to port linux - 2.6.29 on this board. The U-BOOT is already ported on the board and is working. The OS uImage is stored in code flash at address 0xe0000000 and OS is booted by U-BOOT While OS do boot but after some prints weired errors start showing up. Rootfile system is NFS based . I have checked the register values with Hardware person using Trace32 emulator and they are as expected. ---------------------------------------------------------------------------------------- FLASH: 32.5 MB L2: 256 KB enabled In: serial Out: serial Err: serial Net: TSEC1, TSEC2 Hit any key to stop autoboot: 0 WARNING: adjusting available memory to 30000000 ## Booting kernel from Legacy Image at e0000000 ...
