Hello,

As per the subject, I have a little Wemos S2 Mini (https://www.wemos.cc/en/latest/s2/s2_mini.html) that I'm using to make a small DYI board.

When trying to write the firmware to it using the generic ESP32-S2 option 1, I get the following error trace:

Please enter the number of your choice: 1
You have chosen to flash Marauder on a WiFi devboard or ESP32-S2

I can write other images and Arduino sketches to this board using the same COM12 (putting the device into bootloader mode) just fine.

Would you know what could be causing that "PermissionError" above?

Thanks.

Did you try running it as admin? I've not seen that happen. I'm not sure if that specific chip even works with Marauder

Yeah, it's quite strange that it wouldn't flash, but would erase it. I'd only expect it not to flash if it were no longer in bootloader mode, but it shouldn't be possible to even leave bootloader mode after being erased
