Increasing the board's memory

Post by pmacosta »

I are interested in increasing the memory in the CPX (and the PyBadge too). For the CPX, I found a pin-to-pin compatible chip with larger size (https://www.digikey.com/en/products/det ... 10/7100880). The footprint seems a bit larger than the memory chip in the CPX, but with a little elbow grease it just may fit.

My questions is, assuming the soldering/desoldering goes well, does anything in the firmware needs to be changed to have access to the larger memory, or would it "just work"?

Thank you!

Pablo

It depends on what firmware you want to use. For CircuitPython you'd make a minor change to the CPX build to have it use the large memory. I did that way back when with a Feather M0 Express: https://circuitpython.org/board/feather_m0_supersized/ http://daveastels.com/feather-m0-expres ... izing.html. Compare https://github.com/adafruit/circuitpyth ... supersized to the original https://github.com/adafruit/circuitpyth ... m0_express.
