chip:ESP32-C3, IDF:4.4 , examples: blink,espnow,ble_mesh_wifi_coexist
I can debug example code 'blink' project by usb-jtag, but debug error for 'espnow','ble_mesh_wifi_coexist'..etc
i reedit it:
-----------------------------------------
void app_main(void)
{
// Initialize NVS
ESP_LOGI(TAG,"app_main entry.");
esp_err_t ret = nvs_flash_init();
if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
ESP_ERROR_CHECK( nvs_flash_erase() );
ret = nvs_flash_init();
}
ESP_ERROR_CHECK( ret );
while (1) {
vTaskDelay(1000 / portTICK_PERIOD_MS);
ESP_LOGI(TAG,"app_main Delay.");
}// for not run under line code
example_wifi_init();
example_espnow_init();
}
-------------------------------------
if not run example_wifi_init(),i can compile,download and debug, but cancel 'while()...' code, i can compile and download,but not debug for hardware. console tips:

I found : if contains 'esp_wifi_start()' code, compile...download ,run .... usb-jtag is not working, and download , only when switch bootloader mode, to continue download.
Why? wifi and usb-jtag cann't working together?
why usb-jtag disconnect when wifi start?
Re: why usb-jtag disconnect when wifi start?
going on...
if found wifi start appication download to board and run, usb device will change to "unknow device" in computer system,normal usb-jtag working is "USB JTAG debug unit
" in computer system. it looks usb-jtag function is disabled by application! Now,how i debug the board? Where config to use usb-jtag?

Re: why usb-jtag disconnect when wifi start?
Can you try making USB-serial-JTAG into the primary console output? (Menuconfig -> Component config → ESP System Settings -> Channel for console output)
Re: why usb-jtag disconnect when wifi start?
ESP_Sprite :thank you,very much!
set Channel for console output = USB Serial/JTAG controller,done!
set Channel for console output = USB Serial/JTAG controller,done!
