Marlin_FB4S

Marlin 2.0 for Flying Bear 4S/5

Ronald c2b3e88787 Changed 1284p fuse setting for Arduino_1.x.x - Remove the two version of 16mHz. Crystal and resonator use the same fuse setting. Also, Arduino IDE only showed the first one 16Mhz as a board option. - Added 20Mhz board option. Symptoms for incorrect fuse setting: - X axis move in one direction - limit switches fail to trigger - unable to reprogram the device via bootloader - stops working when the reset switch is pressed. - device fails to bootup when power by a slow raise power supply. Solution: - Disabled the jtag - set the correct clock selection bit - set the correct bootloader memory size - enable brown-out setting - enable clock power up delay	11 years ago
