Hello
I recently received KC868-A8S board which I ordered from Aliexpress. I tested almost all sample codes for that board and it worked well but after uploading different sketches like 5 times that board stopped and cannot upload sketch from arduino IDE anymore, even it's sample kincony codes and it is complaining about "A fatal error occurred: MD5 of this file does not match data in flash!". Am having a presentation that am supposed to do with that board tommorow but am afraid that am running out of time and it does not work.
Regards
