Dear board mates,
actually i am interfacing my mcu (atmega32l) with my asic and in the same circuit i am using the spi bus lines for my isp (in system programming) ...
Now the situation is that when i try to program my mcu ( in an external target board using stk500) with asic present on the same chip it doesnt enter in the programming mode however if the asic is not present then i am able to program my mcu
can you please tell me the solution of how to program with asic on the board as without asic my whole circuit would be nothing but silicon dirt
Note : my lock bit settings are that of default one that's no locking on memory , boot ,and application and my fuse settings are default with internal 1 MHZ oscillator clock ( as the stk500 board can provide up to 3.6 MHZ internal oscillations)
waiting for your responses as i am struck!
Regards
Ashish
