PROCESSOR-SDK-AM335X: NFS boot settings

Hi Sanghyun,

Ideally, the U-Boot environment needed for NFS boot gets populated via a serial connection during setting up the SDK, that's why the setup script asks for the board to be connected, etc. Did your install process go through without any issues? You could try to repeat the setup process, keeping an eye for any warnings/error messages that might pop up. You could try to just re-run the <sdk_install_dir>/bin/setup-uboot-env.sh script, or you if you prefer you can just look at it to see what environment it sets up, and model yours after that.

Also you could always setup NFS boot from scratch without the help of the SDK's setup scripts. For example, can you please check this post below, it has the steps needed to demonstrate NFS-based boot on AM335x: 

It is not exactly what you trying to do do (in the post the Kernel & DTB is loaded via tftp, just like the SDK does it, and not via nfs commands), but you should be able to adopt the steps easily. I'll also see I can provide steps that are closer to what you want and update this post.

Regards, Andreas

Sanghyun,

here is a U-Boot command sequence that should allow you to boot any AM335x-based board over network using the Linux SDK v06.00.00.07 as a baseline for U-Boot, target filesystem, etc. Unlike what the SDK sets up, the below command sequence will also load the Kernel and the DTB file from the 'targetNFS' folder via NFS rather than TFTP. I actually prefer doing it this way (using NFS) for development purposes as it helps keeping the Kernel/DTB and filesystem all together in the same folder, all being accessed using the same transport, which makes it easier developing on multiple systems at the same time.

env set serverip 10.0.1.38 && env set bootfile zImage && env set rootpath '/opt/ti-processor-sdk-linux-am335x-evm-06.00.00.07/targetNFS' && env set netloadfdt 'nfs ${fdtaddr} ${rootpath}/boot/${fdtfile}' && env set netloadimage 'nfs ${loadaddr} ${rootpath}/boot/${bootfile}' && env set nfsopts 'nolock,v3,tcp,rsize=4096,wsize=4096' && run findfdt; run netboot

With this, the full boot log looks as follows:
