[SOLVED] error burning .HEX file into atmega328P

i had started out working with microcontrollers recently and its the first time i am trying to burn this.. i just got the programmer 2 days back and with lot of help from another post (https://www.edaboard.com/showthread.php?t=278141) i have made some progress from knowing nothing to something..

but now i am facing another problem...


C:\NEX AVR STK500V2\AVRDUDE\avrdude.exe -C C:\NEX AVR STK500V2\AVRDUDE\avrdude.conf -p m328p -P NEX-USB-ISP -c stk500v2 -U flash:w:C:\Users\Alfie\Downloads\Compressed\at-prog_1287\BLINK.HEX:a

avrdude.exe: stk500v2_command(): command failed
avrdude.exe: stk500v2_command(): command failed
avrdude.exe: stk500v2_program_enable(): cannot get connection status
avrdude.exe: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.


avrdude.exe done. Thank you.




can anyone please help me out cos i have been trying to figure out what is going on...

avrdude.exe done. Thank you.

thanx for all your time and for helping me in every way that you all could...

i did figure out what the problem was...

i just checked the board if there is power being supplied by the programmer... surprisingly there was only getting hardly a 1V reading in the multimeter...
and i was pretty sure that the programmer would supply power to the board cos i had read it in the manual...

and so i went back and started reading the whole manual and then noticed that there is a jumper which can be used to set if power has to be supplied to the board or not... and with that... yes...

Burning successful...

Thank you guys for all your help.....

You all have been of real good help...

thanks sooooo much...
