I haven't built anything for tinyarcade/pocketarcade for a while. I installed the latest arduino IDE (2.1.0). I installed the latest TinyScreen library (1.1.0). I exported the compiled binaries. I copied the .bin to the sd card. It doesn't run. Any idea what could be wrong? Or how to debug the issue?

I've recently seen a few issues come up with custom boards packages used for programming third-party boards, specifically between our SAMD21 boards like the TinyZero and Tiny Arcade.

I recommend that the Legacy IDE be used, the legacy download is available toward the end of the page: https://www.arduino.cc/en/software

Let me know if that solves the issue!

Cheers,

Legacy IDE did work. Thanks. I do hope you fix it to work with the new IDE at some point.
