Esp32-s2-saola-1 ESP-Prog debugging issue

Hi - I’m new to ESP32 and PlatformIO. I am using the ESP-Prog and haven’t been able to get debugging to work correctly.

Here is my setup:
Forum rules for new users wouldn’t let me add pictures, but I can take pictures of my setup if they are helpful.

This is my platformio.ini file:

[env:esp32-s2-saola-1]
platform = espressif32
board = esp32-s2-saola-1
framework = espidf
debug_tool = esp-prog
upload_port = COM7
upload_protocol = esp-prog
monitor_speed = 115200
debug_speed = 500
; force debug mode during normal build & upload (makes backtrace symbols available)
build_type = debug
; enable exception decoding when seen on the serial
monitor_filters = esp32_exception_decoder
debug_init_break = tbreak setup

I’ve used the zadig tool and have one Com port that is the connection to the board’s serial - COM7 and have the remaining USB serial converter B.

I’m using the example hello world code:

#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "esp_spi_flash.h"
void app_main()
{
    printf("Hello world!\n");
    /* Print chip information */
    esp_chip_info_t chip_info;
    esp_chip_info(&chip_info);
    printf("This is ESP32 chip with %d CPU cores, WiFi%s%s, ",
            chip_info.cores,
            (chip_info.features & CHIP_FEATURE_BT) ? "/BT" : "",
            (chip_info.features & CHIP_FEATURE_BLE) ? "/BLE" : "");
    printf("silicon revision %d, ", chip_info.revision);
    printf("%dMB %s flash\n", spi_flash_get_chip_size() / (1024 * 1024),
            (chip_info.features & CHIP_FEATURE_EMB_FLASH) ? "embedded" : "external");
    for (int i = 10; i >= 0; i--) {
        printf("Restarting in %d seconds...\n", i);
        vTaskDelay(1000 / portTICK_PERIOD_MS);
    }
    printf("Restarting now.\n");
    fflush(stdout);
    //esp_restart();
}

The code builds, uploads, and has the correct output when I monitor.

I’m not sure what I’ve done wrong and any help would be appreciated. Function “setup” not defined seems odd to me. I’m not using arduino.

If you can upload via JTAG but not debug there may be a bug in the platform. Please open an issue in https://github.com/platformio/platform-espressif32/issues/.
