Stm32Dev - rev. b (GD32F405 variant)

To further test compatibility between stm32 and gd32 processors, I ordered a batch of Stm32Dev boards with the STM32F405RGT6 MCU replaced with a GD32F405RGT6.
To be absolutely certain that the boards were identical, the same gerbers were used, with only the bom modified (even down to the spelling mistake on the silk screen).
The point of this is to investigate if the GD32F4xx is drop in compatible with the STM32F4xx.
Flashing
To do a command line flash, I usually use the st-flash command.
DFU
It is a little unclear if DFU is supported.
There is no mention of DFU in any of the manuals, but in the datasheet the following is stated:
However, in the user manual it says:
The device refuse to show up as a DFU device, so I'll assume DFU is not supported.
