How to make proper use of ESP32S3 PSRAM / SPIRAM? (Can't build wifi or camera samples for xiao-esp32s3-sense)

[towen]

Hi,

My goal is to build the samples/drivers/video/tcpserversink and samples/drivers/video/capture_to_lvgl for the xiao/esp32/procpu/sense platform, however I am out of memory, and I don't think the 8MB SPI PSRAM is being used properly.

I have added a DTS overlay samples/drivers/video/tcpserversink/boards/xiao_esp32s3_procpu_sense.overlay:

&wifi {
        status = "okay";
};
/* 8MB psram */
&psram0 {
        reg = <0x3c000000 DT_SIZE_M(8)>;
        status = "okay";
};

And I have made a samples/drivers/video/tcpserversink/boards/xiao_esp32s3_procpu_sense.conf with the following:

CONFIG_ESP_SPIRAM=y   
CONFIG_SPIRAM_TYPE_ESPPSRAM64=y
CONFIG_SPIRAM_MODE_QUAD=y
CONFIG_SPIRAM_RODATA=y
CONFIG_WIFI=y
CONFIG_WIFI_ESP32=y
CONFIG_ESP32_WIFI_NET_ALLOC_SPIRAM=y
CONFIG_ESP_SPIRAM_SIZE=8388608
CONFIG_HEAP_MEM_POOL_SIZE=40000

The SPI-RAM chip according to the schematic is a GD25Q64 (8MB) which I believe should be in Quad mode (although the exact type/mode shouldn't matter just to build)

The build fails at the linker stage, with various "DRAM segment data does not fit" messages.

As per my Kconfig, I have tried a few options to move data from DRAM to PSRAM already, and even reduced the Heap Mem Pool to 40000, producing a warning

Am I doing anything wrong here, is there anything else that I need to do to fully utilise the ESP-SPIRAM in Zephyr?

If not, I will make this into an issue - but what is the technical limitation in Zephyr that needs fixing to solve this?

Even the basic samples/net/wifi/shell does not seem to build for this board (for the same out-of-RAM reasons)
Nor does samples/drivers/video/capture

And even samples/hello_world uses 11% IRAM, 12% DRAM, and apparently 14% (1MB) ext_DRAM if I try to enable the SPI-RAM:

There is already an issue for that: #85440
