Hi Folks,

Since the little thing was close to my heart from the beginning, I naturally don't let go of it and am still working on the little one almost every day. So ESP32-Pico-D4 goes PSRAM Power Bank soon.

I did test ESP32-Pico-D4 with 8x8 MB PSRAM Bank and do BANK switching "after boot".
There is a diy technic to do this also "at boottime" with custom bootloader -
and also an undocumented ( have to adjust something so that it is linked )
just testing it for the next time for longtime run.

Of course, keep my thread warm and will report again in due course.



best wishes

Heya Matthias199,
Sorry for the delay - updates are not always noted via email.

ESP32-S3 or ESP32-P4 or ESP32PicoD4 or ESP32 or that PSRAM bank? More Linux Board options available (ESP32, ESP32S3, ESP32P4)
JLYK ESP32-P4 is postponed, waiting for ECO1(2) "Key Manager". S3Linux modules support 64Mbit, 128Mbit, 256Mbit and currently also 512Mbit PSRAM (all OSPI), also WIP 1024Mbit.

How can I help you?

Best wishes
