Request to add the board M5Stack CORE2 to tinyuf2/ports/espressif/boards

[PaulskPt]

The M5Stack_CORE2 has a dual core Espressif ESP32-D0WDQ6-V3 processor. It has: 240MHz dual core, 600 DMIPS, 520KB SRAM, Wi-Fi, Bluetooth, 16MB Flash and 8MB PSRAM.

The M5Stack_CORE2 is not listed in circuitpython.org/downloads,
however the following M5Stack boards are:

Result of search: https://circuitpython.org/downloads?q=m5stack :

m5stack_stamp_c3 by Unknown
m5stack_core_fire by Unknown
m5stack_core_basic by Unknown
m5stack_atom_lite by Unknown

The 'm5stack_core_basic is a predecessor of the m5stack_core2

These boards are not listed in https://github.com/adafruit/tinyuf2/ports/espressif/boards

I would like to create a firmware.bin / firmware.uf2 for the M5Stack CORE2.

Thank you.

esp32 (and also C3) does not have native usb controller like s2 or s3 and therefore it is not possible to support these chips.

OK, thank you hathach!

Afterburner:
@hathach. Can you explain me please. I am not very wel 'at home' with the expression: 'native usb controller'.
What I see is that the product page of the M5Stack CORE2 tells this. See the image:

Then, the device is mentioned in the MS Windows 11 Pro Device manager as soon as I connect the device to the desktop PC using an USB-A to USB-C cable. See image:

The ESP32 and ESP32-C3 do not have native USB on the ESP chips themselves. They use an external serial-to-USB converter chip. That chip only supports serial, not mass storage. So it is not possible to provide the fake BOOT drive that tinyuf2 provides.

Thank you for your explanation Dan. I google'd for that 'native USB' just before my question for more explanation. I did not find what I was looking for. Btw. yesterday I tried to update an NTP sync'ed clock script I wrote earlier this year for the M5Stack CORE2. In the Arduino IDE I received a similar error as you cured for the ESP32-S3-BOX.
