**Since 2 weeks i keep getting the issue that the arduino ide does not want to upload the sketch to the arduino mega 2560. **
The sketch was working absolutely fine but after an update it is not doing the job anymore.
**I have reinstalled the ide, reinstalled the libraries used the older version of the libraries. **
**Tried resseting the mega witth rxo txo and that works sometimes but still doesnt work frequently. ** Overall it is not working as it used to.
But when i open my laptop every morning and connect the arduino, the sketch is working fine without having to upload. But if i try again to upload the sketch than again it doesnt want to upload and it gives the message: Not connected select a board and a port to connect automatically while under the serial monitor it clearly sais that the arduino is connected, than after 2 minutes when it is trying to upload i get an error:
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
Failed uploading: uploading error: exit status 1
**I dont know what the issue is and i have tried a lot of methods to resolve the issue, so if someone can help me out i would really appreciate it. **
