Arduino as ISp

Hi

Had a search for but couldn’t find it !! I’m using the example “ Arduino as ISP” and have it working fine. However if I try a program a second atmega328 then nothing happens ( no uploading , no errors). If I reload the ISP sketch , it again works

( using Arduino UNO, programming Atmega 328p-pu chips )

Anyone help ?

Thx

Is autoreset disabled? If so, try resetting the arduino with arduino as ISP on it with the reset button after you finish programming the first part.

Thx , I’ll look into that - could well be as the heart beat led is still running suggesting the code is still ok
