unable to send/update u-boot over serial console

Hello,

I am unable to send/update U-boot via serial console. The file does not transfer to the board and seems to time-out on the ACK packet.
Besides xmodem I have also tried transferring by using the normal and robust file transfer of kermit itself but that does not work either.

I use the following kermit config

Quote

set line /dev/ttyUSB0
set speed 115200
set carrier-watch off
set flow-control none
set prefixing all
set parity none
set stop-bits 1
set modem none
set file type bin
set file name lit
set streaming off
set protocol xmodem
connect

This gives the following output:

yes, after further investigation this was indeed the problem.

The command to use in kermit is TRANSMIT, not SEND.
