Esp32 S3/P4 compatible 512Mb flash

Postby digitalLumberjack » Wed May 14, 2025 10:04 pm

Hello I would like to know it there is a compatible 512Mb flash for esp32 s3 and or p4.
By compatible I mean for it to be the only flash with data and instructions.

Right now I only found 256Mb flash that can run app.
I managed to use a 512Mb flash, for example GD25B512MEYIGR, but only for data and not for instructions.

Thanks

I am not sure but I don't think so. I believe the flash to cache mapping can handle up to 256 Mb. Which prevents us fom having a larger size for code.
