You can set the CYGNUM_HAL_VIRTUAL_VECTOR_CHANNELS_DEFAULT_BAUD configuration option and rebuild redboot. However I don't think the E7T is that speedy so it may not be able to cope with much more. Try it and see!


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.

It's a known issue that RedBoot has more overhead per character than it really should, compared to other monitors. Sounds like 38400 is the maximum for the moment.
