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


"Artemis SVL Bootloader
Script version 1.7

Phase: Setup

Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader"

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
