Even if I set CONFIG_SPIRAM_IGNORE_NOTFOUND=y in Config, if I try to get the SPIRAM size on a model that does not have SPIRAM, it aborts. (IDFGH-6326) #7988
I am trying to create a program that will use SPIRAM if it is available and work without SPIRAM.
When I tried this two years ago, I was able to create it without any problems.
Perhaps we can call "esp_spiram_is_initialized" in the user program and then branch,
but If SPIRAM is not installed, it is desirable to be able to get the size 0.
esp_spiram_init() … psram_enable() is ESP_OK, set "spiram_inited=true".
esp_spiram_get_chip_size() … if (!spiram_inited) ==false, return spiram size.
without SPIRAM : abort.
esp_spiram_init() … psram_enable() is error, NOT set "spiram_inited=true".
esp_spiram_get_chip_size() … if (!spiram_inited) ==true, ESP_LOG "SPI RAM not initialized" and abort.

Problem Description
I am trying to create a program that will use SPIRAM if it is available and work without SPIRAM. When I tried this two years ago, I was able to create it without any problems.
Probably after the following update, it will now "abort" if SPIRAM is not installed. https://github.com/espressif/esp-idf/commit/bff6b5b70e042dbf5014a7463036fa8e9fc44490
Here
abort()is written, which used to bereturn ESP_SPIRAM_SIZE_INVALID;. https://github.com/espressif/esp-idf/blob/fdfa260b9197a0ef57e5d1d741cbd2e767d86128/components/esp_hw_support/port/esp32/spiram.c#L141-L146Expected Behavior
Perhaps we can call "esp_spiram_is_initialized" in the user program and then branch, but If SPIRAM is not installed, it is desirable to be able to get the size 0.
Actual Behavior
https://github.com/espressif/esp-idf/blob/fdfa260b9197a0ef57e5d1d741cbd2e767d86128/components/esp_hw_support/port/esp32/spiram.c#L160-L171
with SPIRAM : No problem.
esp_spiram_init() … psram_enable() is ESP_OK, set "spiram_inited=true". esp_spiram_get_chip_size() … if (!spiram_inited) ==false, return spiram size.
without SPIRAM : abort.
esp_spiram_init() … psram_enable() is error, NOT set "spiram_inited=true". esp_spiram_get_chip_size() … if (!spiram_inited) ==true, ESP_LOG "SPI RAM not initialized" and abort.
