Can anyone tell me the steps for RPI 3B+ loading custom kernel from u-boot prompt through tftp.
Means i want to compile first
1) custom u-boot
2) custom linux kernel and dtb
Then finally want to load u-boot.bin via config.txt , then while Power On want to load kernel and dtb from u-boot prompt via tftp command. kernel.img and dtb files will be present in my host computer and has configured tftp server.
