Hi Keerthy

We did follow it.

Could you please clarify how to boot kernel and file system in u-boot?

Thanks.

Regards ,

Jack

Jack,

You need to run setup.sh script in your j7200 SDK.

cd $PSDK_DIR
./setup.sh

This will prompt you multiple questions choose nfs and tftp. This will
setup the tftp and nfs servers & set up the file system accordingly in nfs path that
is shown in the script.

Can you please confirm if you have run that?

Pick the bootargs from here: e2e.ti.com/.../3431453

Hi Keerthy.

thanks for your kind reply.

That procedure has been done successfully.

We need to know the command instructions in u-boot prompt to boot up kernel and NFS Root filesystem.

Currently U-boot is flashed into eMMC. then Kernel and NFS Filesystem need to be loaded from Network by tftp.

It's required to boot up kernel and NFS Filesystem in u-boot prompt only. It seem only CPSW2G works in u-boot. LEDs are blinking when cable connected. 

Please let us know the detail steps to config network and load kernel and file system from network. We could not find the information what specified for TDA4 and DRA82x from SDK document.

I will check the bootargs from the link what you give above. 

Many Thanks.

Regards,

Jack
