 Bigger Bigger  Smaller Smaller  Reset Reset

Hello everybody!

I want to use Arduino to flash a atmega 88p at 7,3 Mhz (EXT)

As Serial is used by a slave and I2c is reserved for slave mode i will have to do the whole Upload via ISp.

I need some advice how to program the main Code via ISP in one insatnce thus i have no serial left .
Flashing up the bootloader is quite easy - but how to upload the main Code with the ISP ?(maybe ts that simple i dont get it-...)

Mainly i am concerned about the atmega88p.hex - have no file here for that !

->avr88p.bootloader.file=88p-8.hex

Code:
avr88p.name=ATmega88P / Ext. 7,3728MHz
avr88p.upload.using=arduino:arduinoisp
avr88p.upload.maximum_size=8192

avr88p.bootloader.low_fuses=0xe2
avr88p.bootloader.high_fuses=0xdd
avr88p.bootloader.extended_fuses=0x07
avr88p.bootloader.path=dummy
avr88p.bootloader.file=88p-8.hex
avr88p.bootloader.unlock_bits=0x3F
avr88p.bootloader.lock_bits=0x3F

avr88p.build.mcu=atmega88p
avr88p.build.f_cpu=7372800L
avr88p.build.core=arduino

found out how to program mwith ISP: http://www.arduino.cc/en/Hacking/Programmer

Next Question is the place of the libraries: would like to use the Serial library for enhancing/fastening  my next AVR studio experiments.

Thanks for help!
(and in case : Happy new Year !)

I know this is an old post but just in case someone else has this same issue have written a blog post on how to set up bootload and use a atmega88p
