We are developing on DM368 using the Appro IPNC SDK 4.x, hardware is based on the Leopardboard but using an MT29F1G08AB NAND chip.
After a fair bit of initial confusion getting the board up & running, we had UBL, U-Boot and the kernel & filesys burnt to the NAND with the correct system clocks for the DM368, and could then use TFTP through U-Boot to load updated kernel & filesys during development.
We now have prototype hardware, so it's completely blank, and we have an odd problem.
We are using a bootable SD card to burn UBL, U-Boot etc. to the board, which is what we used originally on the Leopardboard. However, although U-Boot reports no problems with erasing the NAND and writing the images, the board will not boot. It doesn't even load u-boot. However, if we reinsert the SD card, it boots the UBL & U-Boot from the SD card, then picks up the kernel image in NAND and will boot that, although it does throw a lot of ECC errors and has a kernel panic.
Our bootable SD card is executing the following commands:

We've had this NAND problem before but the thread with the answer is no longer around... I believe the issue is around which parts of the image are in which filesystem format, and where the U-Boot nand write / nand write.ubl commands are used. As far as I can see, only the root filesystem is a UBIFS image - In the IPNC SDK we build "make sysall" then "make ubifs" which ubinizes the target filesystem. The kernel is in a file called "uImage" but there's no "ubinize" call on it.
Can anyone tell me where I've gone wrong with this?
