I realize it hasn't released yet, so maybe some of these cannot be answered yet. I'd appreciate at least some info :D . Will the MMU be more full-featured, so normal Linux can be run on the system? Will there be support for faster PSRAM? E.g. something towards 200MHz DDR. Furthermore, ESP32-P4 integ...

Hello, I am working on a project that requires the use of PSRAM and seems to be bottlenecked by its speed. I was wondering what the theoretical maximum PSRAM speed is? I currently use an N8R2 module, QSPI @120MHz mode. I've found out that NxR8 modules have Octal SPI, as well as are DTR instead of ST...

Likely you're not flushing your cache. There's a cache between the PSRAM and the CPU. The CPU accesses the PSRAM through that cache, but EDMA directly accesses the PSRAM without going through the cache, meaning stuff can get 'stuck' in that cache: thr CPU has written it, but the cache hasn't flushe...

Hello, I am trying to get DMA working with PSRAM on ESP32-S3. From what I gather, it employs EDMA (as does ESP32-S2), which allows direct data transfer between PSRAM and peripherals, e.g. LCD. However, I've been unable to get it working properly. I used code from LVGL example in esp-idf as a base to...
