I am trying to flash the NAND with the WinCE operating system on the LogicPD OMAP-L138 EVM in order to do a standalone boot. As I could not find any instructions to accomplish this I followed the instructions for booting from SD card, substituting NAND flash where appropriate. Using the sfh_OMAP-L138 serial flasher host I flashed EBOOTNANDFLASH.nb0 into the nand flash and that all worked fine. I then copied the NK.nb0 file from the release folder to the NAND flash folder using the explorer app. The boot NK from NAND fails and it reverts to booting from EMAC as shown below. What am I doing wrong that is causing the error "ERROR: BLFlashDownload: Image Signature not found 0x0 != 0x43454345"?
