I resolved the issue with flashing by manually putting the devices into bootloader mode.
In particular, for ATOMS3 the trick was to "press and hold the reset button (about 2 seconds) until the internal green LED lights up" as written in the manual :)
Thank you for your replies and kind help!

Hi,
I hope you can help me with the following issue:
Controller tested: ATOMS3 and ESP32-S3-BOX-3
Mac OS: Ventura 13.6
Host computer: MacBook Air, M2 silicon (two computers tested)
After the controller is connected, M5Burner repeatedly shows the message: "Found New Device"
It is impossible to flash the controller with a demo program. The following message is shown after the flashing failed:
--chip auto --port /dev/tty.usbmodem11412101 --baud 1500000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x000 /Applications/M5Burner.app/Contents/Resources/packages/firmware/ffd26b8ba73aefa2a964e2f56d39f1e6.bin
