yes, it is possible. You should provide more information about your system and what you already tried. In my board, i have a rather crude approach for the actual boot command: "run xilinxload&&bootm 0x80000;update;reset" If either of xilinxload [which configures an FPGA] or bootm fails, the update command is executed to allow updating the firmware and after update a reset is performed. This works for me on a coldfire, so in theory it should be possible to replace "update" by another "bootm...". Using bootcount on systems supporting it is a much better solution, unfortunately it is not yet implemented for coldfire. > (maybe it is even possible to compile this into bootloader, in case uboot > environment gets corrupted/misconfigured) IIRC there is a read-only option for the environment.
