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

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