Ideally, it would be best to have a JTAG debugger and step through the execution. A quick-and-dirty approach, is to sprinkle printf() statements after your serial console has been initialized. Off-topic, but for sake of understanding u-boot in general, I'm using the gdb debugger and tracing over the sandbox build (it configures u-boot as a normal linux application). Alternatively, if you can figure out how to use qemu with ARM, that might give you a better idea for your board, instead of following what x86 does. Sadly, I couldn't get qemu-arm working with uboot even after months of trying. :( -Abraham V. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
