after reading this from the manual
"Reminder: If you need to burn the firmware, please press and hold the reset button (about 2 seconds) until the internal green LED lights up, then you can release it, at this time the device has entered download mode and waited for burning."

sometimes i dont do this and it still flashes sometimes not why is it recommended to do this and what can go wrong if i dont hold the button down?

another problem if in the arduino ide i select atoms3 when i connect the board it appears as a esp32c3 and sometimes even other random chips what's going on here?

another odd thing is i have no abilty to control the led in any form with
"
M5.dis.drawpix(0x0000ff);
M5.dis.show();
"
which from looking at the example "https://github.com/m5stack/M5AtomS3/blob/main/examples/Basics/Led/Led.ino" it should work fine.

has anybody else got these problems and could help?
thanks
