Booting via TFTP problem

LYN:

Please halt the boot process to stop at the U-Boot prompt and type:

 printenv

and post your environment settings.  The tftp should worl assuming you

followed all the steps in the wiki article for configuring the atftp server.

Also, check owner and permissions on the /tftpboot directory.

Hello Micheal,

Below is the printout from my terminal. I type the command "run myBoot" at the u-boot prompt to load the kernel. Does atftpd work with ubuntu 10.04?

LYN:

If you still see $'s when you type printenv, it means some of the text substitution is not happening correctly.

probably caused by using single quotes when you should not.   Safest to spell out the entire command.

Note the single quotes and the "back-slash single-colon" which must be typed to escape the semi-colon when the

setenv command is typed. The following should work to get kernel from nand and setup root fs on nfs.

In your example bootcmd was still set for file system on nand flash.

setenv loadaddr 0x80000000

setenv serverip 192.168.1.2

setenv nfshost 192.168.1.2
setenv ipaddr 192.168.1.3

setenv bootfile uImage

setenv rootpath /home/guy/workdir/filesys
setenv nand_kernel nand read.i 0x80000000 280000 220000

setenv boot_nand_nfs 'run nand_kernel\; setenv bootargs mem=99M console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.168.1.2:/home/guy/workdir/filesys,nolock\; bootm 0x80000000'

setenv bootcmd run boot_nand_nfs

NOTE: The tftp command is "tftp" not "tftpboot".  I don't see where you are actually using a tftp command so I am

confused why it is trying to get the kernel via tftp (ethernet instead of nand flash)

Kernel can come from nand or tftp, and file system can be on nand, ramdisk or nfs.  Please specify which

configuration is required.

Hello Michael,

I stopped the u-boot from loading the kernel and typed the following to try to load kernel using TFTP.

run myBoot

myBoot is defined as

myBoot=setenv bootargs $(myBootArgs);dhcp;bootm
myBootArgs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.
168.1.2:/home/guy/workdir/filesys,nolock mem=99M mpurate=600

I didnot boot the kernel from NAND flash.

Please help.

Thanks,
