| Anyone with experience on the Star64? I've had some rough

| the pinebook pro suddenly unable to boot from sd card. Better
| documentation would have helped. I didn't have hours to comb
| through forums and discords/matrices.
|
| Still have a major warm place in my heart for Pine64 though,
| and overall have felt like they're a good value.

| I think they are mostly looking to replace STM32s though.
