Environment Settings for NFS Filesystem in DM814x EVM

Mohammad Kiaei

Hi,

I am trying to boot the DM814x EVM via NAND flash. In order to set the environment for NFS file system, I launched the following commands at the 2nd stage of U-boot :

> setenv autoload no
> setenv nfsserver <NFS server-ip>
> setenv bootargs 'console=ttyO2,115200n8 root=/dev/nfs nfsroot=<NFS server-ip>:/root/targetfs,nolock rw mem=128M ip=dhcp'
> setenv serverip 10.0.1.57
> saveenv

The workspace freezes after "saveenv" and shows the following message:

"Saving Environment to NAND...
Erasing Nand..."

Please, let me know where this problem comes from. Thanks a lot.

Best Regards,

Mohammad

Is NAND enabled on the EVM? Is it detected by U-Boot during the boot process?

Hi Vaibhav,

Thanks for your note. I realized that it works if I set the NAND/SPI switch to 01 instead of 10.

In the next step, I am trying to flash Linux Kernel into the NAND, using the following command:

> tftp 0x81000000 uImage

But, I receive the following message:

"link up on port 0, speed 1000, full duplex
*** ERROR: `ipaddr' not set"

Also, I couldn't find the required command for flashing U-Boot from U-Boot to the NAND. Your comments are highly appreciated.

Thanks,

Mohammad

That would indicate that the board hasn't been assigned an IP address yet. You need to either assign a static IP or get one via a DHCP server.

P.S. Please create different threads for different issues.
