Now I'm really confused.  I got it working by calling esp_log_level_set at runtime. I also figured out I could get it working by changing the value of config_log_default in the sdkconfig.h file which also works and doing a clean build. However, I was wanting to know how to do this at compile time. So I wrote a little stub using the logging library to try and see what the issue was. And I can't get this to print out anything. Strange. Peeking at the definition of esp_logv, I eventually see that the code checks a define called CORE_DEBUG_LEVEL and since this is set to 0 nothing gets printed. I can't find a way to set this.

How do you set CORE_DEBUG_LEVEL that gets generated in Visual Micro? All very strange. This should be so simple to use.



static const char* TAG = "MyModule";

void setup()
{
     Serial.begin(115200);
     Serial.println("setup");
  /* add setup code here */

     esp_log_level_set("*", ESP_LOG_VERBOSE);
     ESP_LOGV(TAG, "Verbose \n");
     ESP_LOGW(TAG, "Warning \n");
     ESP_LOGI(TAG, "Info \n");
     ESP_LOGE(TAG, "Error \n");
     ESP_LOGD(TAG, "Debug \n");
}

void loop()
{

}

Yes, I saw that and tried it also but not working. I added core_debug_level=5 as a define and it generates it but it also generates the original core_debug_level=0 a few lines later that negates it!. So its picking the value up from somewhere.

attached I the build log and the generated file during compilation. If you open the generated file that gets compiled you will see the two defines for core_debug_level. One is 5 and one is still 0.

I re added it to the previous message.. but here it is again..thanks!

Awesome!!! Thanks for that tip! I didn't realize you could override the board.txt properties that way.

Many thanks!
