TMDSIDK437X: Lot Trace Code Clarification for Flashing

Part Number: TMDSIDK437X
Other Parts Discussed in Thread: AM4379

Hi there,

I am working with TMDSIDK437X (AM437x) for flashing purposes. 

I have three evaluation boards with spec number as:

1. AM4379BZDNAI00 - 81CGQ9W

2. AM4379BZDNAI00 - 81CGQ9W

3. - AM4379BZDNAI00 - 7CAQ6DW

For the first 2 boards, they have the same spec number on the chip, and I was able to flash and boot up both of them successfully.

However, for the third board with Lot Trace Code of 7CAQ6DW, when I flash the bootloader to the offset of 0x0. It was fail at 4%. If I try to flash the bootloader with a different offset, it can go through (just not be able to boot up).

Is there anything that I need to pay attention on the Lot Trace Code?

Please let me know if you have any suggestions or hints for this issue.

Thank you,

Minh Vo
