I'm using yocto to build linux for rpi2 and I don't want flashing full sdimg to sdcard. I just want replace kernel image into rpi2 and don't want change rootfs already in sdcard. How I can do that?

I tried delete /boot/zImage in sdcard but I still boot fine and don't have anything happen.

Thanks !

Hy! You tired out this: you write in the config.txt this: "kernel = $your kernel name". Already it helped once for me.

  • Welcome to Raspberry Pi! Please take the tour and visit the helpcenter to see how things work here. Could you please elaborate a little more what needs to be done - certainly it is not all settled just by writing one line in the config?
