Terminating... Thanks for using picocom

I found this github repository https://github.com/rabeeh/u-boot with Dove version of U-Boot. In its README file is section about UART: https://github.com/rabeeh/u-boot/blob/master/README.MARVELL#L131-L138 It points to the file with "w" commands which needs to be executed in bootrom prior doing calling "x" command (which enters into x-modem): https://github.com/rabeeh/u-boot/blob/master/tools/doimage_dove/uart_init.tx...
Could you try to execute all those "w" commands in that other and then use kwboot if it helps?
