I am using an HTCC-AB02A for a project, but after uploading a program, nothing works anymore, I can upload programs, but no matter what I upload, the only thing that happens is that the Serial monitor sends me “Copyright @2019-2020 Helt” on repeat, it stops if I press the reset button or connect the reset pin to GND, but otherwise it only does that. Any idea how to fix this?
Make sure your port speed is set corectly
I have the same issue, port speed is set to 115200, tried various example sketches, all with same result
Is this a dead board?
