  Sorry, I lead you down the garden path there.
  I did of course write the firmware with -w previously. (without any errors)
  This was just to demonstrate that the validating part never works.
  The firmware boots and shows no signs of missing any of it's memory.

  I nearly forgot to mention. This might be relevant

  I never thought much of it because writing went without error and Espruino seems to boot fine afterwards.

  Looked like we cracked it. But no such luck. Not yet.
  Will have to look at it later again. Must get some work done first. :)

  Thanks for your help so far. Very much appreciated.

  RS and CS seem swapped
  CS=C9
  RS=C8

  I have limited time right now to concentrate deeply on it myself (slacking at work)
  But from what I can find in the Chinese PDF the display data lines are still on port B and C

  Will do a 1:1 check later comparing to the HYSTM32_28.py pins

  I understand.
  I really liked the self contained nature of the system with display.
  But I can wait for the proper board.

  I will have a dig around and report back when or if I get it to work.
  The board looks different indeed. I was hoping it's only a board design change.
  The display board has a full size SD card slot. So it has two in total. Not sure how far any other changes go.

  Sorry for spamming. I'm just going to dump a few hints here.

  I had a look at the display board. The only chip I can find on that is the XPT2046 touchscreen controller.
  The LCD controller must be buried somewhere on the actual LCD module. Probably somewhere on the Flat-Flex which is all gunked up with glue.
  No other markings that appear useful.
