Is it possible to send a message to a serial device from the u-boot prompt? Like I would do in a linux terminal with echo "Hello" > /dev/tty2

Thanks

u-boot serial-port

Yes, its possible to send data/write data in Serial port via Uboot. Loading Linux images over UART is possible in that case its possible to do write data to the serial device.

set line /dev/ttyUSB0
set speed 115200
send "hello"

You can just try to use echo or send from the U-boot terminal.

Right now I don't have access to U-boot from my device. This is what I did several times to just handshake serial device from U-boot.
