I see the IDE 1.0 has a new option in the File menu, upload with programmer.
I tried that option using my USBtiny programmer selected and it does seem to work. But I have a few questions.
- Does this option require that the target chip have the bootloader installed or not.
- If not, and the chip does have a bootloader on it, is the bootloader erased once this new upload option is performed with a sketch?
The fuse byte values don't seem to be different looking at hex dumps from when there is a bootloader installed compared to hex dump done after I uploaded a sketch using a programmer option. However a hex dump done using AVRDUDE after uploading the minimum sketch only prints out the first 200 bytes of flash, not the whole flash memory space when I do a hex dump with a chip known to have the bootloader installed?
