Hi,
during my dealing with the bricked kirkwood board I wrote an app which automates the process of booting from UART. It's rather stable now, except right now it doesn't work any more. It's highly configurable, since the external calls to Xmodem and terminal go to shell scripts.
Wolfgang, do you want to provide this app somewhere on your site?
looks like this now:
$ ./marvellserialboot --mode bb --device /dev/ttyUSB0 --baud 115200 Waiting for /dev/ttyUSB0: OK Open /dev/ttyUSB0: OK Set Parameters to 115200, 8, N, 1, SoftwareFlow: FALSE, HardwareFlow: FALSE: OK Clear Recieve Buffer: OK Sending Command Code BB11223344556677: .0x15 OK. Device is requesting Xmodem transfer now. Close /dev/ttyUSB0: OK Starting Xmodem Upload: sx -vv -b u-boot-1.1.4-netgear-533ddr3db-uart.bin </dev/ttyUSB0
/dev/ttyUSB0
Sende u-boot-1.1.4-netgear-533ddr3db-uart.bin, 12288 Blöcke:Starten Sie nun Ihr XMODEM-Empfangsprogramm. Bytes gesendet:1572992 BPS:9666
Übertragung abgeschlossen Xmodem Upload successful. Starting Terminal program: gtkterm Terminal program successful.
regards,
