Memory allocation problem WroverB ADF

Postby profDev » Fri Apr 17, 2020 5:37 am


I'm writing an application in ESP-ADF.
My board is TTGO Wrover B connected via ESP Prog.

All works well till yesterday, and i am not able to getting it working again.

In Initialisation there seems to be a memory Problem. audio_pipeline_init runs in the "memory exhaust" error:

Code: Select all

player->pipeline = audio_pipeline_init(&pipeline_cfg);
	if (player->pipeline == NULL)
		ESP_LOGE(TAG, "Error creating audio Pipeline");
		return NULL ;
Debugger says that it should allocate the Memory with this code in audio_mem.c, nmemb=1 and size = 32

Code: Select all

 data = heap_caps_malloc(nmemb * size, MALLOC_CAP_SPIRAM | MALLOC_CAP_8BIT);
I do not know, if it has something to do with:
Programming without Jtag over serial with make Flash has also error, also with ALL devices DISCONNECTED

Code: Select all

App "play_and_save" version: 1
Flashing binaries to serial port /dev/ttyUSB0 (app at offset 0x10000)... v2.8

A fatal error occurred: Timed out waiting for packet header
make size shows:

      Flash code:  630501 bytes

Pleas help me finding a solution for this Problem.
