DaVinci DM6446-0012 boot problem



Hello All.

I have one problem.. 

I accidentally made a mistake and can`t return to device original state.

I run: sfh_DM644x.exe -nandflash UBL_DM6446_nand.bin uImage-dm6446

Now, the device displays the following message in the cycle:

----------------------------------------------

DM644x initialization passed!

TI UBL Version: 1.50

Booting Catalog Boot Loader

BootMode = NAND

Starting NAND Copy...

Valid magicnum, 0xA1ACED66, found in block 0x00000006.

DONE

Jumping to entry point at 0x81080000.

---------------------------------------------------

How erase flash ?  sfh_DM644x.exe -nanderase not work (Waiting for the DM644x...)

 

  • The problem goes away soldering two resistors R186 \ R190 for switch device in mode to get ubl loader. I mount switcher to on \ off device in BOOT mode.
