Lower Baud Rate about maixduino

[chegewara]

That strange, because its working for me with 1.5Mb without any issues.
You can change this file to add 115200 and test it on your setup:

@chegewara

Thanks a bunch. I will definitely give it a try after a cursory review (not that I understand exactly what is going on beneath the covers ;)) but simply to improve my learning. I will let you know as soon as practical on the results. Right now, my tactical focus is to ensure that I have a basic understanding of the available library of MicroPython modules (because my skimpy Python knowledge is interfering). Again, appreciate your continuing support.

FWIW, I suspect that @loboris' suggestion to use the -B goE option and the lower baud rate must have been the combo to unlock my issue. As you mention, I did try 115200 bps, 0.75, 1 & 1.5 Mbps earlier and was not successful. Now that 1152000 will let me flash I do not want to press my luck with a faster speed right now. As you can understand, MCU hardware is not my expertise.

Of course, I have to manually RST the board after a flash although the schematic and specs indicate (per @loboris) that it should have been automatic.

Kind regards.

P.S. I've been waiting for help since the end of May. I am very fortunate that @loboris and you pushed me in the right direction. Many thanks again.
