Question: PSRAM, is there a way of setting this up as a separate heap? #1815

Hi Guys,

I have a Pimoroni Pico Plus 2 here, and I have the PSRAM mapped and working

I have had a look through the sdk docs and I am not sure how to set this memory up as some form of secondary heap, is there anything built into the sdk for doing this?

Many thanks

Andy

We at SparkFun have a working solution here, in case that helps: https://github.com/sparkfun/sparkfun-pico?tab=readme-ov-file#replacing-the-integrated-memory-allocator-routines

Thanks for the info.

I ended up knocking a c++ wrapper up: https://github.com/AndrewCapon/PicoPlusPsram
