ATTiny45 flashing problems
#1
Hello,

i tried to flash my ATTiny45 like it is shown in the pilight manual and i am using a raspberry pi 3. (could this be a problem because of the clock rate of the pi 3)

But i get only this error:

I checked the wiring more then 10 times - should be ok.
I also changed the chip - same problem.

Does anyone have a idea to fix this...

Hi,

i have solved the problem for me.
Looks like the rpi 3 was the problem... Changed the LPF to my raspberry 2, dit the same wiring, same flash procedure and it worked.
Back to the rpi 3 without problems...

May anyone check the flash procedure on a rpi3 to checkout if there is a general problem with the rapid

Thanks
