I am trying to flash my DM368's NAND using TI's flashing utility (sfh_DM36x.exe) using UART. I've tried it on both Linux and Windows. Whenever I do I get the following error message:
Target: Writing UBL to NAND flash
Target: Unprotecting blocks 0x00000001 through 0x00000018.
Target: NAND is write protected!
Target: Writing failed! Starting UART boot...
Obviously the NAND isn't being unprotected. Any tips on how to flash the NAND via UART? Here's an example command I'm using in Windows:
e:\Temp\board_flash>sfh_DM36x -nandflash -p COM3 UBL_DM36x_NAND.bin u-boot-dm368-evm.bin
