Dear Zeyad A,

Hello,

Please help me to configure u-boot in my NC600 board.

What's this board? Is it supported mainline? What CPU does it have, what version of uboot etc?

My board is the thin-client NC600 board with POLLUX loaded(same as the device in this link: https://code.jeffkent.net/trac/nc600/wiki/Hardware/Devices/NC600#no1). It has 64 MB of ram and 64 MB of storage space. I had followed the writings in this link: https://code.jeffkent.net/trac/nc600

I don't see this being supported by mainline u-boot, right? So what version does your board run? It might be that the u-boot you run is broken too.

...

I have reached near to u-boot, but the kernel is not booting. After the kernel image upload

via

...

serial boot mode it is giving no response.

Kernel or uboot? Maybe your xyzmodem uploader doesn't work with uboot? Minicom worked for me.

I have done all these in ubuntu 11.04 as per the link. In the terminal in ubuntu, i can start the u-boot by ./boot-uboot command and my FTDI serial communicator is working fine. All the things are sending to the board and it is entering to u-boot. The commands are working fine in u-boot.

Ok, so you have u-boot running and it's the kernel that doesn't boot? What is the last think you see?

...

If the kernel image upload become complete it is not giving any command line in the u-boot as shown

in

...

the guide.

I see ... what terminal emulator do you use to communicate with uboot? btw. uploading via tftp over the ethernet is usually much faster.

I am using ubuntu terminal and it's working good. I tried both tftp upload and direct flash memory upload by plugging the flash in my board's usb port. But in tftp upload the kernel image upload was successful. The led indicator in the board is blinking at the time of kernel upload. But after upload, there is not getting any response in the terminal. I can't do any commands in the terminal.

...

The memory is not getting flashed.

Why of course, the loady command downloads data to RAM, you have to flash it via "nand write" or such command afterwards.

Yes the data is uploading to RAM. After that i can't do any commands. This the only problem i have...

Ok, so you're uploading it to RAM, are you sure you don't overwrite u-boot? Check where u-boot is located (run bdinfo) and avoid that location.

It is again booting the same old windows CE in the nand boot mode.

Thanking you, Regards
