I tried to upload Code from one Uno configured as Arduino as ISP to a second Uno. As long I use SS Pin10(standard) everything is working just fine.
But when I try to change the SS Pin to Pin5 e.g.:
#define RESET SS
to #define RESET 5
I get the error message: avrdude: stk500_recv(): programmer is not responding
I already tried to change the SS Pin in the pins_adruino.h without success. Does anyone has an Idea? The goal is to use in the end one Uno als ISP Uploader to upload code to 4 more Unos with differnet SS Pins for selection of the right Uno.
