Hello,

I’m using bootloader to program my AT90CAN128 over CAN. After programming the device with FLIP, the INT0 pin must be ‘high’ while resetting the processor so that the application can be started. I searched the datasheet but could not find any relevant information about this aspect. Can anybody help?

Thank you
Senmeis

The bootloader section was empty at factory.
So aspects of your bootloader can not be covered by the AVR datasheet.

You must look on the documentation of the bootloader, which you have programmed into the fresh AVR.
