Maix-Bit V2.0 programming problem

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.

#3

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?

Hi there~



I am checking with the designer and will keep you posted here. thanks.

Hi there~



You can select maixduino board to download for Maix bit v2.0 as temporary solution. we will add MAIX Bit V2.0 support this week. thanks.

That works, thank you!

#7

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

#8

Hi there~



Please update maixduino to rev 0.3.10. It can solve the issue. thanks.

This seems to have come back in 0.3.11. I too can not get past the

In ArduinoIDE (using Arduino SDK) or PlatformIO with Kendryte standalone, or FreeRTOS.
