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?
HTCC-AB02A stopped working, only sends a copyright notice through serial
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?
