If no update is available, perhaps we can consider ignoring the checksum on TGP systems if one of the following conditions is met:
1. SW compatibility bit is not set (current Jacek's approach)
2. The checksum word at offset 0x3F retains its factory default value of 0xFFFF.
I am already on the latest firmware. I have also tried downgrading to earlier versions and they have the same problem.
Ok, so in this case I think that we should go with option 2.
Jacek - can you please add this check to your patch?
