Need avrdude help- MinimOSD (MEGA328P) Bootloader

[lasakro]

I know this topic is beaten to death but it's also killing me. I'm new to avrdude and Arduino in general. I'll run through the steps and please tell ne what I'm doing wrong. I'm not sure I have a successfully loaded boot loader at the end:

1) Upgraded my USBasp firmware so that I don't receive the sic error or whatever it was.
3) Run:avrdude -c usbasp -p m328p -U lfuse:w:0xFF:m
(Good)
4) Run:avrdude -c usbasp -p m328p -U hfuse:w:0xDA:m
(Good)
5) Run:avrdude -c usbasp -p m328p -U efuse:w:0x05:m
Now this returns:

Code: Select all

Would you like this fuse to be changed back? [y/n] 

I select no.

6) Run:avrdude -c usbasp -p m328p -U flash:w:ATmegaBOOT_168_atmega328.hex

Output:

avrdude done.  Thank you.

So do I have a functioning bootloader? I try to upload install the latest MinumOSD software and I can't get past uploading the firmware. Can't update EEPROM or configuration file. Can't upload character set. To get the firmware to upload I had to manually press the reset button even though my FTDI adapter DTR signal was connected. They have a thread on RCG but it's really dedicated tot he firmware, not issues for bootloader:

Could you please say, what device you are trying to load that bootlaoder.

And let me ask, why are you not using the Arduino IDE to load that bootloader? Hex file comes with the Arduino IDE. See pic.

And I don't mess much with the command line of avrdude . I use AVR8_Burn-O-Mat, when I have to use the usbasp. Makes things easier ...

It's in the title

MinimOSD did not ring the bell

But there is a ISP connector and why not flash the bootloader with usbasp and Arduino IDE?
Don't have to fuzz with the command line of avrdude ....
