TDA2: Cannot save uBoot env

Kevin Tsai

Other Parts Discussed in Thread: TDA2, SYSBIOS

Hi all,

I want to boot TDA2 EVM with NFS.

I follow the document, VisionSDK_LinuxUserGuide.pdf, and do followinf steps:

setenv bootargs 'console=ttyO0,115200n8 vram=16M root=/dev/nfs rw nfsroot=172.24.170.60:/datalocal/user/abc/vision_sdk/linux/targetfs rootwait ip=dhcp mem=1024M'

setenv fdt_high 0x84000000

setenv bootcmd 'load mmc 0 0x825f0000 dra7-evm-infoadas.dtb;load mmc 0 0x80300000 zImage;bootz 0x80300000 - 0x825f0000'

save

But it shows error message:

Saving Environment to MMC...
MMC init failed

zImage, dra7-evm-infoadas.dtb, MLO and u-boot.img are already copied to SD card.

Is there anything I missed?

My environment is TDA2, Linux + sysbios, Vision SDK v2.10.

Thanks.

hi,

I guess you have to set your NFS server address correctly

below one is for TI NFS server

nfsroot=172.24.170.60:/datalocal/user/abc/vision_sdk/linux/targetfs

pick the file uenv_nfs.txt, modify with your NFS server address, rename to uenv.txt and copy to SD card.

Hi Shiju,

Thanks for your reply.

I did change NFS address and path when I typed the command in console.
But I forgot to change it when I typed this post.
I am sorry for that.

The error message mentions "MMC init failed".
So I think something like pinmux should be modified.
But the document does not describe about this.

By the way, your sugestion is modifying uenv.txt directly instead of typing command at uboot, right?
I will try it. Thanks.
