Reboots on Serial read: Use Fuse L:0xf7 #15

Open zevero opened 9 years ago

zevero commented 9 years ago

I lost a day, because I experienced frequent resets on serial reads. This did not occur on the pins of Serial1 only on Serial and EVEN on an empty sketch without Serial.begin just with a short blink on a led in setup() to indicate the reboot.

Well the solution was for me to use Low fuse 0xf7 instead of 0xff.

Please add a footnote somewhere, since I think that many will run into this issue! I myself tested it with 3 different setups and Atmega1284p .... and I am still not sure, why this occured...
