Bootloop

Did anybody seen similar?
I have no idea how to repair.

If you cannot download firmware automatically anymore you'll need to force your M5Stack device into download mode manually. Connect a wire between GPIO0 and GND. Then power on the device. It should now be in download mode:

rst:0x1 (POWERON_RESET),boot:0x0 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_FEO_V2))
waiting for download

When you see that output you can remove the wire and proceed to download new firmware.

Note: if you do not remove the wire you can still download firmware, but upon resetting the device it will go into manual download mode again instead of running the new firmware.

Right, OK, nobody panic!
There is a bug somewhere that causes a random boot loop to appear in the ESP32 and strangely I had this with a Stamp the other weekend.
Disconnect everything and leave the controllers unconnected for a while, cold boot the computer and try and flash UIFLow firmware.
