ESP32 to chromeos crostini

Hi all,

I have a chromebook with the linux beta installed. I want to code my esp32 with this device, I installed the arduino IDE with linux and the uart to usb drivers are installed standard. Only I always got the error, timed out, waiting for packet header. I keep struggeling. I have a Windows pc and here is it working with no problem, but I can't find the problem on my chromebook.

Can someone help me?

Thanks,
Sam

I have the exact same problem - but instead using PlatformIO (in VScode).

But tell me, how did you manage to install the ESP32 boards in the Arduino IDE Board Manager? When I add

https://dl.espressif.com/dl/package_esp32_index.json

to the Preferences window, and then choose ESP32 in the Board Manager to install the boards, I get a error message:

Tool xtensa-esp32-elf-gcc is not available for your operating system.

How did you overcome this step?
