Found it! The 15pF capacitor C6 connected from XTAL_P to GND did somehow not harmonize with the ESP32C3 and the crystal selected. Removed C6 and it booted stable. Coulds see this "invalid header" (1) at boot what means there is nothing flashed so far. Then flashed it (2), and everything came up corr...

Dear ESP32 forum, i have made a new design using the ESP32C3 FN4 with 4 MB Flash on chip hence i am not able to load code or bootloader into the chip as i see a constant rebooting after a very short random time like shown here (1), restart reason is sometimes printed as "rst:0x13 (GLITCH_RTC_RST)". ...

Maybe i have now an explanation, while checking power supply and find its stable with 3.31 Volts and no glitches when the problem occurs, i crosschecked all the hardware again, and found something that has to do with the handling of IO12, that i use to monitor an external switch. This IO pin i progr...

Schematic is here, its a high frequency DC/DC converter in typical application, powered either via USB or external 12V source that is also connected:
