I tried 57600 and 115200: at 57600, using ckermit, Redboot displays its
banner and understand incoming commands, however gdb fails to upload
binaries to the board. At 115200, the board is unable to communicate
with either ckermit or gdb.
I don't understand why gdb is able to talk at 57600 to Angel (target
rdi) but not to Redboot (target remote)...
