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?

Hello,

Apologies if this has been answered before.

If I have 2 BMCU units on an A1 and flash them as unit A and unit B, as per the instructions, will unit A work on its own if unit B is unavailable or would it need reflashing as a single unit?

Essentially, you have to flash particular firmware for multiple units to work together but does that then stop them working standalone, if needed?

Thanks
