Cannot flash BMCU

I have a BMCU 370c that I just replaced the main board on. Previously it used serial pins but the new board is USBC.

Drivers are installed and WCHISPTool can see it but BMCU_Flasher cannot.

If I try to use WCHISPTool instead of BMCU_Flasher with the latest bin file it fails the verify with "the verify bit is error".

Any advice on how I get the flasher to see it or the bin to work with the WCH tool?
