Greetings from planet earth to @all

We hope to add PSRAM to cope with occasional and rather large parallel buffering.

Q: Where do we enable the external PSRAM and pin mapping in ESP-IDF? My understanding is this is currently supported for the PICO-D4 however I can't seem to find where the options are in menuconfig. Do I need to set PICO-D4 as target somewhere for this to show as configurable parameters?

Thanks in advance for any pointers, I'd appreciate.

Found where you set the cs pin so I'll just answer my question for the record/others (see screen grab for ref). Great toolchain btw, @espteam. Now that we have the environment working, located the essential doc and have the hardware mapped out, we'll proceed with ordering a pair of Pico V4.1 ref modules and few D4 SiPs + ESP-PSRAM64H. Let's see if we can RFC one of our product line with your solutions, should go smooth from here. Thanks.
