 This will leave the "OS" partition (3MB (nand sectors 0-18), containing BooSt and the kernel) alone and erase the rest of the flash (except from the 4MB user partition - use fe8 instead of ee8 to nuke that too). The partition command defines the "OS" partition block e8 (ie being 3Mb - 18blocks for BooSt, the rest for the Kernel and Initrd). This will leave the "OS" partition (3MB (nand sectors 0-18), containing BooSt and the kernel) alone and erase the rest of the flash (except from the 4MB user partition - use fe8 instead of ee8 to nuke that too).

 Once the card and boost have been prepared, simply insert the cf card. If you observe on the serial console you should see the nand being programmed. Once programmed the boot should continue and the system should now be bootable from nand. Once the card and boost have been prepared, simply insert the cf card.
