RGB Pins occupied by PSRAM

[mmoukayed]

Describe the bug
My board uses pins 16, 4, 17 for builtin rgb led, but everytime i try to make a custom board for it, it keeps telling me that the pins are used by psram.

To Reproduce
Create a new board.json with this code in it:

"led": {
        "rgb": [
            {"pin": "LED0"},
            {"pin": "LED1"},
            {"pin": "LED2"}
        ]
    },

and run npm run build
Expected behavior
The system should build succesfully and I can flash the firmware to my board.
Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
The board is an ESP32-2432S028R.
This is the output of npm run build:

> testno2@0.0.0 build
> npm run build:devicescript


> testno2@0.0.0 build:devicescript
> devicescript build src/main.ts

Michał Moskal (@mmoskal) any idea?

Right, 16 and 17 are used by PSRAM if PSRAM is installed. I assume your board doesn't have it. I guess we should have an option in the .board.json to disable PSRAM checking, however the board is unlikely to work very well anyways due to lack of a native USB interface.

From https://microsoft.github.io/devicescript/devices#implementation-status

The ESP32-C3 boards are best supported. The regular ESP32 (without -C3 or -S2) currently have issues with the USB connection (as it's handled by external chip). The ESP32-S2 has limited memory which makes it difficult to use TLS. The ESP32-S3 is very recent and largely untested.

The RP2040 should generally work, but TLS is not supported on Pico-W.
