Running Linux from NFS

noahberhanu · ‎04-22-2022

I have managed to build and run U-boot, kernel and rootfs using SD card. I am now attempting to run Linux from NFS using the same bundles I used for SD card. I am using the same SD to use the same U-Boot image but configured U-boot setting to get rootfs from NFS but the process aborts with kernel panic.

Any help regarding where I may have messed up is greatly appreciated. I see the error messages but no clue how to resolve them.
