I am getting this:
>fboot17.exe -b57600 -c3 -p50_robot_sharpIR.hex -v50_robot_sharpIR.hex
COM 3 at 57600 Baud: Connected
Bootloader V1.7
Target: 1E9307 ATmega8
Buffer: 960 Byte
Size available: 7680 Byte
File 50_robot_sharpIR.hex open failed !
Program-Error
I have followed the instructions on the website here, went through em twice.
I have the hex file in the proper folder.

I changed the hex filename to ranger.hex and it worked. I bet its 8 characters or less for the filename.

I've found that I can only program the robot once using fboot.exe. The second time around it won't even connect.
Its like it over writes the boot loader section of flash.
I have looked at the ATmega8 Datasheet and on page 212 it talks about BootLocks. I have programmed BootLock11 which is suppose to block SPM from being able to write to the bootloader flash.
That still didnt work. I think its still over writing the bootloader flash.

ok Disregard that last post. I had the USB breakout board powered up wrong.

funny thing, I recently had the exact same problems as you, and solved them in the same way :P
(Ill update the bootloader tutorial when I have time to address these issues)
