Hello! I've got some blank atmega 328p-au's without a bootloader. Is it possible to upload a bootloader via a FTDI programmer?
but I don't know of anyone who actually tried it.
Much better is to use a proper ISP programmer. If you have an Arduino board, use it as an "Arduino as ISP" programmer:
If you're going to do this regularly, spend a few dollars to get a dedicated ISP programmer. My preference is the 6 pin USBasp from the Chinese sellers on eBay.
Thanks! I’ll try that!
You’re welcome. Good luck!
