Error calling psram library and missing esp_rom_gpio_connect_out_signal function in esp32s3-hal library

[gho1b]

I encountered an error while trying to use the psram library in my code using the psram::init_psram(peripherals.PSRAM) function. During my investigation, I discovered that the esp32s3-hal/ld/rom-function.x file in the Espressif source code documentation for the ESP32-S3 does not include the esp_rom_gpio_connect_out_signal function at address 0x40001aa0.

To solve this issue, I successfully flashed the device by adding the following line of Haskell script:
PROVIDE(esp_rom_gpio_connect_out_signal = 0x40001aa0);

My question is why doesn't the esp-hal library include this line? What will happen if I force the implementation of this line myself?

I have no idea why we missed that but we need that ROM function for sure.

If you want we would be happy to get a PR for that - otherwise I can do it early next week.

Additionally we should make sure to check it in CI to avoid regressions

Thank you for your clarification. So far my device have no problem when i impletent the code. I will make the pr asap
