Hi,
I am trying to do serial boot on pandaboard.According to Pandaboard
specifiction(Page 22) I have changed the sys boot order to 101101(MMC1-
>UART).
I am doing following steps.
1>compiled x-loader for omap4430-panda_config( source code taken from
here :git://gitorious.org/x-loader/x-loader.git xloader)
2>compiled u-boot for omap4430-panda_config(source code taken from
here git://git.denx.de/u-boot.git u-boot-main)
3>Then i used following tool to do serial boot (git clone
http://github.com/nmenon/omap-u-boot-utils.git)
I transfered x-loader with following command
./pserial -p /dev/ttyUSB0 -f x-load.bin
above command give me following output
Waiting For Device ASIC ID: Press Ctrl+C to stop
ASIC ID Detected.
Sending 2ndFile:
Downloading file: 100.000% completed(12700/12700 bytes)
File download completed.

4> Then when i try to transfer u-boot to the x-loader with the
command
./ukermit -p /dev/ttyUSB0 -f u-boot.bin
it just stops and nothing comes.

what are the configuration change needed to Generate an x-loader with
serial support ??
PLease suggest
