If the leds are flashing really, really fast, then the checksum of the kernel-partition (in flash memory) does not match the checksum in the partition table (in flash memory). There are at least two reasons for that to happen: The kernel partition in flash is corrupt. The kernel partition is stored in more than one flash chip and the rescue code hasn’t been configured to account for the hole in the address range (CONFIG_ETRAX_FLASH1_SIZE in kernelconfig). You need to check the sizes of your partitions and chips to figure this out. If you have more than two flash chips on your board, check CONFIG_ETRAX_FLASH1_SIZE, it’s supposed to be set to the size of the first chip.
