What happened?

I was trying to install the FluidNC onto a esp32-s3 using the install scripts present in the release, however that gave me the error presented above. After that, I also try to compile the PlatformIO version both the [env:wifi_s3] and [env:noradio_s3]. In the build, it gave the following error:

In file included from /home/pm/.platformio/packages/framework-arduinoespressif32/tools/sdk/esp32s3/include/hal/include/hal/uart_hal.h:30,
                from FluidNC/src/Uart.cpp:12:

    uart_clkdiv_reg_t div_reg = hw->clkdiv;

Is there anything that I'm doing wrong? Is the support for the s3 still not completed?

We do not support S3 yet.

[MiguelASTavares]

Do you have a timeline for when it could be supported?

[MitchBradley]

Anything we support ends up being expensive for us because the number of people who ask questions far exceeds the number of people who contribute to the project. Supporting S3 would double our release engineering and testing time, and would mean that we have to have more hardware for testing. We are already overwhelmed with support questions, for example from people who blew up their ESP32 and asked a lot of questions, only to realize that they plugged it in backwards.

I have also tried to install the FluidNC on an ESP32-C3. The installer runs, but once it's in the console state it crashes with the error:

ESP-ROM:esp32c3-api1-20210207

I also tried to install on a ESP32-S2, but the process stops with the secure boot msg. Do you have an alternative way to install in a ESP32-S2 with the secure boot active?

@MiguelASTavares have a look at the wip s3 branch
