ESP32 Micromod plus Machine Learning board not flashing

Tried to flash ESP32 Micromod plus Machine Learning board from Arduino IDE via USB. Not working

Using the following settings

Board: Sparkfun artemis micromod

Bootloader: Sparkfun Variable loader

SVL baud rate 115200

Using Windows 10 O.S.

From PC I have set on device manager: (ports COM&LPT) Silicon labs CP210X USB TO UART Ports setting 115200 8N1

Got the following errors while trying to upload Blink example sketch;

C:\Users\alteria\AppData\Local\Arduino15\packages\SparkFun\hardware\apollo3\1.2.1/tools/artemis/windows/artemis_svl.exe COM7 -f C:\Users\alteria\AppData\Local\Temp\arduino_build_113391/Blink.ino.bin -b 115200 -v

We have read the forums and users’ comments for hours without finding any possible soution or workaround to the problem.

Then tried to upload new bootloader using the same set up

Got the following errors:

"Connecting over serial port COM7…

Also no solution found. Tried different speeds, and combination settings to not avail.

Please help

Correct me if I’m mistaken, but it looks like you are using the Artemis board files while using the ESP32 - the ESP32 guide has a thorough walkthrough and the relevant links/libraries https://learn.sparkfun.com/tutorials/mi … rogramming

Also please ensure which version of the Arduiuno IDE being used (must be 1.8 or later)

Hope this helps!
