I also noticed that without using additional system calls, this can partially work, but only when using TX. As soon as I connect the RX, the Wi-Fi driver cannot be initialized. I am using external UART-USB adapter to test this scenario. Here is a logs: I (24) boot: ESP-IDF 4.4.2 2nd stage bootloader...

Hi, the datasheet say: USB - GPIO18 and GPIO19 are USB pins. The pull-up value of a USB pin is controlled by the pin’s pull-up value together with USB pull-up value. If any of the two pull-up values is 1, the pin’s pull-up resistor will be enabled. The pull-up resistors of USB pins are controlled by...

Hello guru, I need to use ESP32-S2 pins GPIO19 (USB_DM) and GPIO20 (USB_DP) as UART, but when I try it, the module is reboot continuously. I think is due to USB internal pin pull-up. The ESP32-C3 datasheet it directly say that pull-up resistors of USB pins are controlled by USB_SERIAL_JTAG_DP_PULLUP...
