Im trying to use a 1284P chip with Arduino and iv found a couple guides online but Im needing help setting up with adding files to show up under the boards drop down to select it. Im using a mac and using Arduino 1.6.12.
I’v used that link for trying to install the boot loader onto the 1284p but it comes up with an error. I’v attached the files I’m working off of and a screen shot of the tools menu showing the info for the chip. Heres the error code
Arduino: 1.6.12 (Mac OS X), Board: “ATmega1284, Standard, 1284P, 2.7v, Disabled (default), 16 MHz external” avrdude: Version 6.3, compiled on Sep 12 2016 at 17:22:25
Are you sure that the crystal is connected properly and working? Check all connections to/from crystal. The wires should be short. Make sure the caps are making good contact and that their other side is connected to ground.
0x000000 sig frequently indicates that fuses are set for external crystal, but said crystal is not present or not working.
Also check ISP wiring
When you bootload, it will set the fuses, exit and reenter programming mode (latching the fuses) and then write the bootloader. If the clock source you chose (crystal) wasn't present, the first - and only the first - time you bootload it, you'd see it successfully writing the fuses, and then failing with 0x000000 sig (this is a 100% guarantee as to the nature of the problem, if you catch it at the time!). After that, it fails immediately, since now the fuses are set to use the non-working clock source
