Hi members!
I want to inform you about the following fact that in Arduino IDE it is now possible to choose the amount of PSRAM for the board Adafruit Metro RP2350 with PSRAM (ADA6268).
The story:
Yesterday I received an ordered Adafruit Metro RP2350 with PSRAM (ADA6267) from Pimoroni.
Today I tried to use a PSRAMtest sketch in the Arduino IDE v.2.3.5.
It did not run. Investigation revealed that the “boards.txt” file failed “menu.psram” definitions, like I saw that they exist for the Adafruit Feather RP2350 HSTX board.
This afternoon I created an issue (#2960) on arduino-pico. The maintainer, EarlePhilHower, was very helpful and resolved the problem swiftly by adding the necessary code into two files. He immediately created a PR which by now has been merged to the main repo.
I copied the two files changed. I put these files in their respective places (this is not the way to do it!). Then, after restarting the Arduino IDE in the menu > Tools there appeared the item “PSRAM Size” which in fact is a list of four items. I chose the option “8Mbyte PSRAM”. Then I ran the File > Examples > rp2350 > PSRAMtest again. It built and it executed flawlessly!
I expect that it will take a day before the official updated release will be available inside the Arduino IDE.
Greetings,
Paulsk
