Subject: dm355:ecc query
Hi,
I am reading "sprufb3.pdf".
I found following point on page 157.
"Copy the User boot-loader from NAND flash to IRAM with hardware
ECC error detection enabled. If a
4-bit ECC read error is detected, the UBL will correct the error
via the ECC correction algorithm. If the
read fails due to any other error, the descriptor search process
begins anew in the next block after that
in which the UBL descriptor was found for up to the first 24
blocks. If no valid UBL descriptor is found
after searching 24 blocks, the RBL will try to boot via MMC/SD."
Can anyone explain me what does this mean?
Regards,
Jitendra
