My STAM PLS stopped working after updating from version 2.4.4 to version 2.4.5. I used M5Burner to revert the firmware back to 2.4.4. But the STAM LPC program didn't work. OSError 261
Fully agree that, a 8 or 16 M psram will significantly enhance the experience of Cardputer ADV, but shortage of GPIO could be a major problem.
Maybe we could a version of ADV with S31 in the future.
