自制ESP32-C3板 烧入例程Hello-World卡在软复位上

[Bosspoipoi]

自制ESP32-C3板，下载调试均采用USB接口，无串口转USB的芯片。
menuconfig中已经修改了控制台的默认输出为USB/J-TAG 模式。

ESP-IDF版本：master
芯片硬件版本:V3

下载后打印如下：

之后就没打印了，这是正常的吗？以前用ESP32 会不断重启打印的。
请问应该考虑哪方面的原因?

补充说明:
芯片版本：内置FLASH版本，芯片是V3的

我量了下UART0 也就是IO21，在执行esp_restart后有明显的波形，说明IO21也就是UART0是有输出的。
但是我已经在menconfig中将打印输出设置为了USB_JTAG接口，而不是UART0
