Ticket Name: TDA2: Cannot save uBoot env

Query Text:
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, Kevin, VSDK expert is notified for your questions. Regards, Mariya

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. regards, Shiju

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. Kevin Tsai
