Description

Ensure that the new flash chip is stable with the existing firmware strategy. It has some hybrid 64k/4k sector option or a 256k sector option. From Panos' reports it seems to behave well when I treat it as a 256KB sector device and oddly when treated as a 64KB sector device.

Gathering ids on other boards in case I need to switch on that: Flash_chip_by_board

Flashing a new PDM is very clear that the board is erasing in 64KB blocks. That does not explain the core corruption on saving settings though.

I'll set the block size to 64KB when spotting this ID and see how it does!

I've received my board a few months ago and am unable to reproduce. Working fine as far as I can tell with the 64KB flash size.

I'm guessing I'd provided Panos with a strange test core which we ended up flashing. No idea what it was doing!
