Maix-Bit V2.0 programming problem

Post by bruceh » Wed Jul 10, 2019 7:24 am

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:
...
Sketch uses 322706 bytes (3%) of program storage space. Maximum is 8388608 bytes.
[INFO] ANSI colors not used
[INFO] COM Port Selected Manually: /dev/cu.usbserial-00001014B

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

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?

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