Can I upload a bootloader via a FTDI to a 328p-au?

Hello! I've got some blank atmega 328p-au's without a bootloader. Is it possible to upload a bootloader via a FTDI programmer?

Theoretically, yes:

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!
