WIFI driver initialization failed due to lack of RAM

[Laurent]

Hello,

As the following traces show, I don't have enough internal RAM available in the ESP32-S3 when initializing WIFI.
OK, that's possible, my project need a lot of internal RAM. But why when I make PSRAM memory available, I still don't have enough memory available for WIFI?
(KCONFIG with: SPIRAM true, Octal Mode PSRAM enabled, SPIRAM_TYPE Auto-detect, SPIRAM_TRY_ALLOCATE_WIFI_LWIP enabled).
There's 8 MB free in the PSRAM!

Has anyone ever run a project with WIFI using all or part of the PSRAM? I'm on ESP-IDF version 5.3.1.

Thanks in advance.

WiFi always needs some buffers (e.g. dma descriptors) to be in internal memory. Maybe you somehow managed to fill up your internal memory by so much that it cannot allocate that?

Yes, this works fine.
WiFi connection works even without a USB camera.

Thank you nopnop2002, your project confirms that it can work.

I think ESP_Sprite is right, WIFI needs a minimum amount of internal RAM, whatever the allocation strategy chosen.

I therefore need to monitor the consumption of internal RAM during the initialization of the various modules when my software is launched. I'm not very familiar with the Espressif Framework. Are there any primitives that can be used to monitor the different sections of internal RAM?

I've already tried the esp_get_free_heap_size() function, but that's not enough, it doesn't monitor the sections reserved for running the drivers.
