Hi All,
I am trying to bring up one of our custom Davinci board through UART.
First I have issued the following command
1. sfh_DM644x.exe -nanderase
This command was executed successful.
Then I ran the following command
2. sfh_DM644x.exe -nanflash ubl_davinci_nand.bin
u-boot-1.2.0-davinci.bin
I get response that NAND Blocks 1 through 5 are all BAD. Is there a way
to clean this up or do I need to replace NAND?
The Terminal window output is as follows.
