Is the process of burning a bootloader (JChristensen's mighty-1284 to be precise), on an Atmega1284 microcontroller same for both DIP (Atmega1284p) and tqfp (Atmega1284-au)?
While searching online I found very little information about the tqfp version of the chip.
Also, I would like to use internal or external 8 Mhz oscillator (crystal) as my board should run at 3.7V from lithium ion battery charged with MCP73831 lipo charging chip. Should I just change the fuse settings in the Arduino IDE boards.txt file (and should I use the fuse bits from Atmega1284 datasheet) or there is something else that also should be done?
Here are my schematics:
