I've got a Sipeed M1s Dock board which powered by M1S module (based on BL808 chip). I tried to burn it with official Bouffalo Lab Dev Cube utiluty like that:
1) I connect the board into PC via "UART" connector
2) I press "Boot" button
3) I press "Reset" button
4) I release "Reset" button
5) I release "Boot" button
After that I guess my module in a boot mode because there is no images on LCD (the internal project should show one)
6) I choose the highest UART in Dev Cube (in my case COM7, there are COM5 and COM7)
7) I set UART speed to 2000000
8) I press "Create and Download" button on Dev Cube
9) I've got an error (log is attached below)
