Interesting phrasing Yes sorry, what I meant to ask was if accessing NVS/FAT from task where stack is in external RAM is something that is expected to work or not, given that it do work on 4.4.4 and not on 5.1.2. I have a project with several task with stack in external RAM, all of which are readin...

I made an example where I can reproduce the issue: #include "esp_log.h" #include "nvs.h" #include "nvs_flash.h" #include <freertos/FreeRTOS.h> #include <freertos/task.h> #include <string> #define TAG "MAIN" #define NVS_STORAGE "storage" #define NVS_READ_WRITE_TASK_STACK 8192 nvs_handle_t _nvs_handle...

Hi! I'm using ESP32-S2 with an external 2MB PSRAM. In my program I have various tasks, all of which where I allocate the task stack in external RAM (using CONFIG_SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY and xTaskCreateStatic() with EXT_RAM_BSS_ATTR StackType_t _main_event_stack[MAIN_EVENT_TASK_STACK]). In...

Hi! I'm using the esp-adf built in ogg decoder, but I'm unable to make it output anything other than 16 bits ints. My DAC support 24 bits, and I would like to utilize this. There is nothing in the ogg decoder configuration to configure this, as far as I'm aware. This is what I get from the decoder: ...

Yes this is possible. I'm using ESP-ADF on a ESP32-S2 to stream music from an remote HTTPS server, decrypt it, OGG decode it and then feeding it to the DAC, at the same time as there is a web-server running, another websocket connection open as well as continuous separate HTTPS calls happening (for ...

I found the issue, with help from this one: https://github.com/espressif/esp-idf/issues/300 There where actually three problems: 1) the one that they suggest in the link, that is, push data to I2s only once, after the loop. 2) I had changed the sample rate from 36000 to 32000, but I hadn't changed t...

Hi! I have an external DAC, namely a CS4344, that needs a MCLK that is 256x LRCK. Documentation states "there is no required phase relationship, but MCLK, LRCK and SCLK must be synchronous". There are some threads here touching the subject: https://esp32.com/viewtopic.php?t=1585 https://esp32.com/vi...

Hi,
Did you find an answer to your question? I'm also interested in how to output the master clock.
