Is your feature request related to a problem?

Hi, core FastLED dev here.

I wanted to ask a question:

Why is -mfix-esp32-psram-cache-strategy=memw not specified in the arduino build manifest for the esp32s3, along with board_build.partitions = huge_app.csv?

espressif/idf-extra-components#473 (comment)

This would unlock our I2S library to control LEDs to work with the ArduinoIDE, without hacks.

Is there any plan to provide these build settings as default in the future?

Describe the solution you'd like

I'd like the necessary build flags provided to the ArduinoIDE compiler as defaults.

Describe alternatives you've considered

You can hack ArduinoIDE to get these build settings in.

Because this is only needed for old esp32 revisions with PSRAM.
No other MCU needs this.

Thanks for the fast response.

The second question I have is it looks like a partition.csv is needed for PSRAM to work. Is that true? Or am I mistaken. Sorry if this is a dumb question.

[Jason2866]

There is no relationship between PSRAM use and partition.csv. The clear answer is use whatever partition.csv fits best to the use case of the sketch.

Thanks the response!
