It breaks when handing over from at91bootstrap to u-boot. It is possible that your u-boot really break here, but cause we do not see any output from u-boot (the version line) it is likely that you have mis configured at91bootstrap here. However it may be some mis misconfiguration in u-boot too. The relevant parameters are CONFIG_SKIP_LOWLEVEL_INIT, CONFIG_USART_BASE/CONFIG_USART_ID. Please check that these are setup correctly. Regarding the at91bootstrap please check the following questions: * Can you verify, that you have written your u-boot binary (the *.bin file) at offset 0x20000 into your NAND? * Can you also verify that your u-boot image is not bigger than 192 kBytes? * Have you checked that the ECC mechanism used when writing the u-boot into NAND do match the oob layout the mechanism used to read the u-boot out of NAND? * Can you please check that you have more than 64MiB SDRAM connected and correctly initialized by at91bootstrap?
