Option to reduce baud rate for burning firmware #7

Open mfhepp opened 6 years ago

mfhepp commented 6 years ago

Thanks for this great tool! When trying to burn the firmware to an Adafruit Feather board, I was running into continuous problems. It turned out that some USB chips require a slower baud rate, like 115200 baud, see also here: https://github.com/cnlohr/espusb/issues/8

It would thus be good to be able to set the baud rate in the configuration, so that you can use e.g.

$ esptool.py --port /dev/cu.SLAB_USBtoUART --baud **115200** write_flash --flash_size=detect 0 ~/.upiot/firmwares/esp8266/esp8266-20180511-v1.9.4.bin 2>&1

Before report an issue, please make sure it hasn't been reported before.

Operating system

OSX 10.11.6

Board used

Adafruit Feather

Description of problem

Burning firmware fails due to too high baud rate.

A quick solution would be locate the json file located in uPiotMicroPythonTool/boards an edit the --baud parameter manually. You should edit the file corresponding to your board/firmware

Thanks, I found that in parallel and tried, but it did not really help. Currently, ampy on the command-line works fine, but the same functionality inside Sublime Text does not.

That is a pity, because in theory this plug-in is exactly what I need - a Sublime-based integrated workflow for MicroPython development that works via the USB UART.

Has anybody this running with Adafruit Feather boards (ESP8266)?

This plugin uses a modified version of ampy, but it shouldn't be a problem.

You are having problem to burn the firmware or to run the ampy commands?
