Is an ESP32 capable of running rockbox?

Trzyzet:
The most powerful ESP32 has about a 0.5MB of RAM. I think it's not enough.

This device is built around an ESP32-WROVER module with two ESP32 cores @230MHz, and 8MB of QSPI-attached external PSRAM.    Use of PSRAM will yield a perforamance hit but the overall system shoud still be plenty fast enough for the full rockbox feature set.

(I'm 95% certain only 4MB of PSRAM is directly mappable at a time, but it _should_ be possible to play games with the MMU to work around that)

Is there any price estimate ?

Yep, the ESP32 reference manual is pretty explicit that the entire virtual address space is 4 MB -- the MMU section makes this a bit more obvious. I think it'd be like PAE on x86, if you could segment things into processes of 4 MB max memory you'd be okay. But trying to use all 8 MB from a single process would be impossible without major hacks.

The ESP32-S3 has 32 MB of virtual address space, however, which would be plenty.
