3 cips 3 diffrent problems atmega644pa-pu
well have 3 microcontrollers 3 different problems
atmega644pa-pu
i use arduino isp, work other cips; schematics uploaded below
mi question witch 1 ded ??
1 .
i can burn boatloader - ok (tried more )
i have led on d0 in bootloader must blink , - ok
no errors
================ problem
when upload sketch makes pins blink ... alll dead
any sketch upload not work
2.
burn bootloader
avrdude: verifying ...
avrdude: verification error, first mismatch @ byte 0x0000
0xff != 0xfd
avrdude: verification error; content mismatch
upload sketch
avrdude: verifying ...
avrdude: verification error, first mismatch @ byte 0x004a
0xb9 != 0x79
avrdude: verification error; content mismatch
avrdude: send: q [51] [20]
3.
burn bootloader
avrdude: device signature = 0x000000
avrdude: yikes! invalid device signature.
double check connections , try again, or use -f override
this check.
upload sketch
avrdude: device signature = 0x000000
avrdude: yikes! invalid device signature.
double check connections , try again, or use -f override
this check.
the connections fine because have other cip , work fine
is not on breadboard ... fixed no lose wires
can unbrik 1 of them ?

guys should use next
i used avrdudess
and avrdude
same thing arduino ide ..... same problems
i can read fuses , write them atrmicrocontroller 1 2
but @ 3 0x00 low high , extended
