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 and PlatformIO. I wrote a small program to test the debugger:
Code: Select all
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);
}Code: Select all

The board is powered over USB.
I got the following output when PlatformIO starts OpenOCD:

Please note: I have already asked in the PlatformIO forum, but they can´t help me.
