The actual issue though is the specific board design is missing the connections from pins 38 and 40 of the RPi GPIO to the STM32. The board is also missing manual boot jumpers, so there is no way to get the STM32 into bootloader mode to update it by the UART, hence the need for the programmer since the board designer did incorporate the ST-Link port and connections.
If someones previous actions are any indication of their future actions, then I predict the deletion and removal of access will happen at any moment. 7-11-2020.
