At least the GD32F1 and other STM32F103 clones have genuine ARM
numbers in the Romtable PIDR. Furthermore, they have newer core
revisions.  In Blackmagic I accepted code for the GD32E230 in the
stm32f1 code paths. I did not test due to missing test target, but it
indicates that the romtable number are not the ST romtable numbers.

If Michael could test against BMP/hosted and confirm  GD32E230
detected and working, I 'd be gratefull. With an Stlink/Jlink/CMSIS
Dap/Ftdi adpater connected the right way, this would be "blackmagic
-t" for a first test, after compiling in src "make PROBE_HOST=hosted"

Cheers
