DM6467 serial flasher hangs during nand operation

Hi All,

 

i am using custom DM6467 board and trying to erase NAND.

There is no progress after the "UBL sent..." message.

 

And same for the flashing operation as well.

sfh_DM646x.exe is expecting second DONE message.

 

Can anyone tell me what should i do ?

 

Console messages captured are as follows:
