Hi,
I try to use the JTAG debugger on my ESP-WROVER-KIT-VE in an Arduino and the esp-idf environment with Visual Studio Code. I wrote a small program to test the debugger:
static void applicationTask(void* p_Parameter)
{
setup();
while(true)
{
TIMERG0.wdt_wprotect = TIMG_WDT_WKEY_VALUE;
TIMERG0.wdt_feed = 1;
TIMERG0.wdt_wprotect = 0;
micros();
loop();
}
}
static void StartApplication(void)
{
initArduino();
applicationHandle = xTaskCreateStaticPinnedToCore(applicationTask, "applicationTask", CONFIG_ARDUINO_LOOP_STACK_SIZE, NULL, 1, applicationStack, &applicationBuffer, CONFIG_ARDUINO_RUNNING_CORE);
if(applicationHandle == NULL)
{
}
}
extern "C" void app_main(void)
{
StartApplication();
}
#include <Arduino.h>
void setup(void)
{
Serial.begin(115200);
}
void loop(void)
{
Serial.print("Hello\n\r");
delay(1000);
}
And my configuration file:
[platformio]
src_dir = src
[env]
board = esp-wrover-kit
platform = espressif32@1.12.4
framework = arduino, espidf
board_upload.flash_size = 4MB
board_upload.maximum_size = 4194304
board_build.partitions = other/partitions.csv
upload_speed = 921600
upload_port = COM6
monitor_speed = 115200
monitor_port = COM6
monitor_filters = esp32_exception_decoder
debug_tool = ftdi
debug_init_break = tbreak app_main
platform_packages =
framework-arduinoespressif32 @ https://github.com/marcovannoord/arduino-esp32.git#idf-release/v4.0
toolchain-xtensa32@3.80200.200512
[common]
build_flags =
# ESP32 specific
-D ARDUINO_ESP32_DEV
-D BOARD_HAS_PSRAM

lib_deps_builtin =
lib_deps_external =
[env:debug]
build_type = debug
build_flags =
${common.build_flags}
-D DEBUG
lib_deps =
${common.lib_deps_builtin}
${common.lib_deps_external}
The code is working on the development board, but the debugger doesn´t start. I´m clicking on PIO Debug inside of the debug menu and I got the following output:

Sometimes the debugger starts and throws this error:

What is wrong here?
