ESP-IDF. support for DMA to/from external RAM

Postby Mariusz » Tue Mar 21, 2023 8:32 am

Hello! 
I am using ESP32-S3.
I have a question regarding support for external RAM. In your document (https://docs.espressif.com/projects/esp ... l-ram.html) you have stated that "Note, although ESP32-S3 has hardware support for DMA to/from external RAM, this is not yet supported in ESP-IDF."
It is really crucial for me to know when will you support DMA to/from external RAM in ESP-IDF. It is a crucial part of the project.
Kind regards,
Mariusz

I'm decently sure this is an old remark that no one ever removed, compare e.g. what's stated here. I'll make an issue to remove this sentence from the docs if it's indeed not applicable anymore.
