ESP32-S3 possibly incorrect flash pins (M5Stack Cardputer) about devicescript HOT 11 CLOSED

@pelikhan Hey! Thanks for your work on this project! Obviously I'm excited to get js running on this thing, I don't think many people have (most of the code out there is in c++ via arduino) and I'm really glad this project exists. Just would love to know if my guesses above as to what's going on is correct, if so does a new release need to be made (something out of my hands), or is it possible I can override the flash pins arch config from userland?

@reggi thank you for digging info on GPIO33~37 - I think the upcoming 2.16.2 release should fix it - it now labels the pins in question as octal-flash so should let you have the config you want!

Even the Espressif ESP32-S3 board here has a pin 35 in the image so this isn't something unique to the M5Stamp, right?

I don't know what a "flash" pin is 😭, does M5Stamp need it's own Arch? Or is the ESP32-S3 configured wrong?

@mmoskal is it possible adding pins 35-37 in this commit was a mistake?

Perhaps this line from the docs clarifies something, this is wayy new to me 🙃🤯 https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/gpio.html

SPI0/1: GPIO26-32 are usually used for SPI flash and PSRAM and not recommended for other uses. When using Octal Flash or Octal PSRAM or both, GPIO33~37 are connected to SPIIO4 ~ SPIIO7 and SPIDQS. Therefore, on boards embedded with ESP32-S3R8 / ESP32-S3R8V chip, GPIO33~37 are also not recommended for other uses.

@mmoskal thanks for handling this so quickly! I wanted to report that I reflashed (with a custom board that I should put in a package) the device and got the LCD working! I'll be making a package specifically for the cardputer, if anyone has any trouble on here with anything tag me!

Feel free to contribute back into this repo if it easier for you. Thanks for circling back!

Using https://microsoft.github.io/jacdac-docs/tools/device-registration/ we can register that M5 board so that it gets a nice icon in the dashboard.

@pelikhan this wants a PAT, and I really don't wanna do that 🙃, is there another way?

Can I just manually make a PR? Like this one: https://github.com/microsoft/jacdac/pull/1349/files

Feel free to ignore it and do a PR with the board.json and picture. Thanks!
