problems with burning bootloader

Other Hardware 3rd Party Boards
1

I've been burning bootloaders on the chips that I got a few days ago. I had a few failed attempts that were remedied by either re-seating the chip or replugging the jumpers but one particular chip just keeps failing on me. I'm using Nick Gammon's burnbootloader sketch. below is what I keep getting (using my UNO as the programmer for a atmega328p-pn). Did I simply get a bad chip?

You have the "divide clock by 8" fuse set. Try clearing that first. Use the "hex uploader" sketch on this page:

You can run it without an SD card to change fuses. The wiring is different, sorry. Check the diagram on the page.

Arduino     ->  Target Atmega328
-------------------------------------

D4 (SCK)     Pin 19 
D5 (SS)      Pin 1 (reset) 
D6 (MISO)    Pin 18 
D7 (MOSI)    Pin 17 

+5V          5V 
Gnd          GND

Change the low fuse from 0x62 to 0xE2. Once you have done that you should be able to program the bootloader.

Thanks for the help, when I upload that sketch and get to the part about "choose fuse" I type in LOW but nothing happens so I type it in again and this is all I get:

UPDATE: I had to change the following line in the sketch from this:
UPDATE2: I had to modify a few other similar lines to get the sketch to work. It appears that it wanted a certain number of characters before the program would process it so I had to change the character array sizes to match the sizes of my responses.

// get which fuse
  char response [6];

to this:

// get which fuse
  char response [4];

After making the fuse value change I tried the to upload the bootloader and was successful. Thanks!

I'm glad that worked. The sketch works as written however you probably did not have the serial monitor set to send a newline. So when you pressed it just send LOW (without a line terminator). Next time, set up the monitor to send newlines when you hit Send and the original sketch will work. After all, LOW, and HIGH have different letter counts, and it would be tedious to have to recompile every time just for that.

Ah, thanks. I just checked, and I didn't have it set to send a newline.
