build UBL and U-BOOT and boot from NAND flash on the LEOPARD368

Olivier Singla

I have rebuilt both the UBL and U-BOOT, and I am able to boot the Leopard368 board using them, bootfrom from a SD card I built using uflash.

Now I want to boot from NAND Flash, and these 2 boot loaders will not start if they do not have the UBL signature, that's at least my understanding.

What tool should I use to create the UBL signature for eavh of these files, is that mkimage with the -T ublimage option ?
In that case, I am missing the config file that the -n option want...

Any help on this will be greatly appreciated!
