use other module OK。
but why?

What power supply (LDO) is on your board? What 3.3V decoupling do you use? I suspect your power supply is inadequate, causing the board to brown out and reset.

my board used dcdc XL1509 150KHZ ,max 2A
1: I used USB TTL 3.3V + ESP32-C6-WROOM-1 module test faild;
2: I used my board 3.3V + ESP32-C6-WROOM-1 module faild
3: I used my board 3.3V link to ESP32-C6-DevKitC(no 5V) test ok

In other words, the 3.3V itself seems solid, but you may be lacking decoupling or something that causes the ESP32 to brown out. Can you post full schematics of the ESP32 and power supply situation, including any decoupling caps? Also the PCB design if you're able.

yes ,ESP32 No decoupling capacitor was added，I think ESP32-C6-WROOM-1 there is.
my be must add it;

Agreed; it's a long way from U5 to the ESP32 module. Probably one or two ceramic 10uFs between the 3.3V and GND located close to the ESP32 will fix the issue.
