Is it necessary to flash-kernel? Once /boot on HD is populated with the new kernel, doesn’t it finally boot from that and it doesn’t matter what version is flashed?

Congrats!

Do you think that dpkg –i … on the ss4000e would upgrade the installed stock kernel to a customized one compiled by buildroot or make-kpkg?

Sadly, for me, dpkg -i doesn't seem to update the /boot/vmlinuz and /boot/initrd.img symlink; I'm not sure it runs flash-kernel either.

After running dpkg -i for the image and headers I go to /boot to make sure the symlinks are ok, make sure the vmlinuz file ends with iop32x and then run flash-kernel and then checks if it would fit the 2MB MTD region and it flashes.

After reboot if works fine.

Maciej
