Well, it is done, but still boot from flash. I forget to do step 6. I subsitute with this, chroot /mnt/initfs cal-tool --set-root-device ask:mmc2 and does not seem to work. There is error statement though. OK, I will try step 6 and see how it goes. I do not want to install any progs on flash, that is why I want to clone to MMC as my first project. I inserted a 4G SD on the ext slot, it was recognize immediately, thank god. Edit: mission accomplished, booted from MMC2 bun
