Dear friends,
I am new to this board and had to reprogram Linux image and rootfs. I made it by the procedure described into the GESBS-9G20 user manual, but U-boot does not start Linux. Please, advise. For easier check I apply below the environment variables of the board:

U-Boot> printenv
ethaddr=3a:1f:34:08:54:54
bootdelay=1
baudrate=115200
bootargs=mem=64M console=ttyS0,115200 root=/dev/mtdblock2 rw rootfstype=jffs2 mt
dparts=atmel_nand:1M(bootloader),3M(kernel),-(rootfs)
bootcmd=
ethact=macb0
bootfile=uImage
filesize=1A7A38
fileaddr=22000000
gatewayip=192.168.0.141
netmask=255.255.255.0
ipaddr=192.168.0.235
serverip=192.168.0.37
stdin=serial
stdout=serial
stderr=serial

Environment size: 391/131067 bytes

Thanks in advance.

Dear Super Hero,

Find the U-boot log attached.
There is only this log file in the work folder.
I am not sure is it helpful, but I send you attached copy of the Hyper Terminal window.

Thanks for support.

You U-boot environment variable bootcmd is not set.  The U-boot will not automatically load OS without the bootcmd variable being set.  Please set it to,
nand read.jffs2 0x21000000 0x100000 0x200000; bootm 0x21000000
