Maix-Bit V2.0 programming problem

[bruceh]

I have Maix-Bit V2.0 and cannot program it from Arduino using Maxduino(K210) Version 0.3.9 on Mac Mojave 10.14.5, arduino 1.8.8
I can program a Maix-Bit V1.09 successfully.
Version 2.0 error:
...

Please help. I just purchased 50 of these boards. Neither port /dev/cu.usbserial-00001014A or /dev/cu.usbserial-00001014B work.

Hi there~,

Please check if the usb cable is 4 wires for data transfer. thanks.

Yes. The same cable and software programed a Maix-Bit V1.09 successfully.
Perhaps the k-flash programmer software didn't get updated correctly in Maxduino(K210) Version 0.3.9 to support the Maix-Bit V2.0?

That works, thank you!

Do you have an estimated delivery time for Maxduino(K210) Version to support the Maix-Bit V2.0?
