Hi,all,
I met a problem on DM6446 custom board.
I use CCS and nand writer to burn ubl and uboot to nandflash, the step and message is as follows:
Init NAND Flash Ok!
4096 Blocks...
131072 Pages...
64 Mbytes...
Do you want to erase all block about Nand Flash?

Enter ubl file name...

ubl file size 14336
Writing ubl to Flash ....waiting for checking the erase information!
Write: ubl_header[6] and ubl image now!
Congratulations on Writing ubl into Flash successfully....

Enter uboot file name...
u-boot.bin
uboot file size 152680
Write: ubootheader[6] and uboot image !

Dont't need to write uImage!
when I burn the kernel and file system using tftp and uart, some times It will appear the message as follows:
TI UBL Version: 1.12, Flash type: NAND
Booting PSP Boot Loader
PSPBootMode = NAND
