Kermit Not Responding). I debugged this on the getc level and verified that my board's U-Boot can accept the first few data from my PC's kermit and then the loadb function hangs, i.e. does not accept any data. I think this is because my UART's FIFO is not handled well, and probably needs software flow control.
Are you sure the problem is on the receiving side (i.e., did your PC Kermit continue sending after your board stopped receiving)?
It could also be a synchronization problem (i.e., the UART in your PC is clocked slightly faster than the UART on your board); you can relax that by setting the PC (but not your board) to two stop-bits.
Anyway, if you really need flow-control, then I'd strongly recommend hardware (RTS/CTS) over software (XON/XOFF) for reliability reasons (an XOFF (or worse, an XON) might get lost on the line).
