Compilation fails when using esp_apptrace_init() - JTAG

[n47h4n]

Hello everyone.
I'm trying to build a small program for testing JTAG 2-ways communication.
I have the error:

Code: Select all

/Users/nb/.platformio/packages/toolchain-xtensa-esp32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: /Users/nb/.platformio/packages/framework-arduinoespressif32/tools/sdk/esp32/lib/libapp_trace.a(app_trace.c.obj):(.literal.esp_apptrace_init+0x10): undefined reference to `esp_apptrace_jtag_hw_get'

[...]
collect2: error: ld returned 1 exit status
*** [.pio/build/esp-wrover-kit/firmware.elf] Error 1

This error disappears if I remove the line containing a call to esp_apptrace_init()
I'm working under platformIO in CLI mode.

I'm lost...

Here's the small code:

Code: Select all

#include <Arduino.h>
#include "esp_app_trace.h"

esp_err_t res;

void setup() {
  Serial.begin(115200);
  /* Init communication JTAG */
  res = esp_apptrace_init();     <====== line that cause the error
  if (res != ESP_OK) {
      log_e("Failed to init JTAG communication");
  }
}

void loop() {
  /* Send to PC */
  char buf_to_pc[] = "Hello World!";
  res = esp_apptrace_write(ESP_APPTRACE_DEST_JTAG, buf_to_pc, strlen(buf_to_pc), ESP_APPTRACE_TMO_INFINITE);
  if (res != ESP_OK) {
      log_e("Failed to write data to host!");
  }
  res = esp_apptrace_flush(ESP_APPTRACE_DEST_JTAG, ESP_APPTRACE_TMO_INFINITE);
  if (res != ESP_OK) {
      log_e("Failed to flush data to host!");
  }

  /* Receive from PC */
  char buf[32];
  char down_buf[32];
  size_t sz = sizeof(buf);
  
  /* config down buffer */
  esp_apptrace_down_buffer_config((uint8_t*) down_buf, sizeof(down_buf));
  /* check for incoming data and read them if any */
  res = esp_apptrace_read(ESP_APPTRACE_DEST_JTAG, buf, &sz, 0/*do not wait*/);
  if (res != ESP_OK) {
      log_e("Failed to read data from host!");
  }
  if (sz > 0) {
      /* we have data, process them */
  }
}

And here's the platformio.ini file:

Code: Select all

[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino
upload_speed = 921600
monitor_speed = 115200
build_type = debug
debug_tool = esp-prog
build_flags = -DBOARD_HAS_PSRAM
              -mfix-esp32-psram-cache-issue
              -DCORE_DEBUG_LEVEL=4

Is this an espressif issue or a platformIO one?

Any help would be greatly appreciated.
Thanks in advance.
Nathan.

The arduino libraries are not compiled with jtag apptracing active. You will either need to build your own arduino libraries with lib-builder, or build from scratch in platform.io using `framework = espidf, arduino` and a customized sdkconfig

Thanks for your reply @lbernstone

I don't understand what you mean by "a customized sdkconfig".
Is there a doc somewhere?

[lbernstone]

Maybe some documentation somewhere on platformio website.
