Using pre-built firmware with Maixduino #12

Closed baqwas closed 5 years ago

Hello, I'm having teething problems deploying the pre-built firmware to the Maixduino board. The following command from the unarchived firmware working directory reports that K210 cannot be detected! ./kflash.py -p /dev/ttyUSB0 -b 2000000 -t MaixPy.bin

I have attached a document listing the steps performed to arrive at the last command. I would appreciate some guidance on troubleshooting the issue. In the interim, I am trying to build the firmware for a subsequent test as a workaround activity.

Problem per suggestion by @loboris on another thread to use a lower baud rate owing to known issue with USB/serial interface. Used 115200 and it worked fine but had to RST the board before continuing use in REPL mode.
