How does one upload a sketch to a Pro Mini (without the bootloader) using another arduino?
I have a UNO, and when hooked up to a pro mini like this, (I know, it`s not a mini in the diagram) I can burn a bootloader without a problem.
I can upload a sketch with a UNO (328 removed) when it is hooked up to the pro mini like this (last picture at bottoom of page).
The problem is I want to upload a sketch without the bootloader to utilize all the RAM. I uploaded the ISP sketch to the UNO, in the preferences.txt I set
uploading.using=Arduino as ISP, disabled auto reset with a capacitor, and made sure to select the pro mini board from the list. No luck. When I try and upload the Blink, I get this error message:
