[avr-gcc-list] AVRDude command line options

[Robert Ussery]

Hi, all.

I've just started using the AVRDude program, and there are a few things I
don't yet understand. I ran AVRDude using the sample program (after having
compiled/linked/etc. it, and having obtained the .hex file) using the
following command:

avrdude -p at90s8515 -c STK500 -e -m flash -i c:\demo.hex

This worked, except that I received the message: "WARNING: the -f, -i, -I,
-o, and -m options are deprecated. Please use the -U option instead."

After investigating the -U option, I tried again with:

Avrdude -p at90s8515 -c STK500 -U flash:w:c:\demo.hex
And
Avrdude -p at90s8515 -c STK500 -U flash:w:"c:\demo.hex"

neither of which worked. I received the message:
"Invalid file format '\' in update specifier"

Clearly, what avrdude is doing is interpreting the ":" in c:\ as the
separator between the file name and file type sections of the -U command. Is
there anything I can do to remedy this (other than putting AVRdude in the
same directory as the .hex file)?
Thanks!

In the meantime, I guess I'll just continue using the -i and other
"deprecated" commands.
