Topic: arduino uno error (Read 498 times) previous topic - next topic


i accidently uploaded the sketch on arduino as isp while the board selected was arduino mega 2560,
and now the ide is giving the error
avrdude stk500_getsync(): not in sync resp=0x30
and sometimes it says the signature of the microcontroller is incorrect
so i connected another m328 preloaded with arduino ide but the same error persists.
also somebody tell me how to overcome he problem of wrong signature on other microcontrollers
cause i read that it is very common to happen with the microcontrollers
but the avrdude keeps on rejecting them giving the "yikes" or the "signature" message
even if we know that the mc we are using is pefectly fine!
also i have connected all the wires correctly and checked them well
power was correct
in short everything else was fine!!!!!

kindly give the solution quickly since the date of my project submission approaches
thanks in advance!!!!


What do the RX and TX lights do when you try to upload a sketch?
