    and the block that sits on it (connected by some purple mat to the actual heatsink):

    I expected it to be like the 6560 in size! It's labelled S109AFTG - I've been sold a totally different board

    OK looking into datasheet, the TSD and ISD modes on this chip require more than just disable/enable to recover, so it's probably one of those, and since it's happening towards the end of a job it's maybe pointing more towards TSD error. Will reset heatsinking and try again.

    OK, opened all the boxes, reduced clearance to heatsink and replaced foam pads with silicon grease. Heat sinks now getter hotter and no fail yet...
