and just to add, v0.2.3 firmware is on the edge of not needing the link to induce thew bootloader of stm32.
Can't remember if needed or not on this version? if not then link has to be made.
what is happening on screen at the moment..is it white??
It sounds like the dfudemo is playing ball, but there is no handshake to the bootloader from the vna.
