I have a systems using a Freewave Radio in Point-to-Point mode for a console connection. I am working system debug and would like to be able to interrupt u-boot with a keystroke, so I can bypass booting into my application. However at the application level flow control was added to eliminate an issue I was having transferring files. With Flow control on I can no longer break into the u-boot sequence and change the start-up options, boot to application vs boot to os.
My current u-boot does not support hwflow, it apperar to be a stubbed out function in the serial_imx.c file. Has any one added the code to enable handshaking with a u-boot bootarg?
