This is probably a simple matter, but whenever I try to run a command to a so-far-unused USBASP device, I get this error:

 

>avrdude -c stk500v1 -p m8 -P com1

avrdude: stk500_getsync<>: not in sync: resp=0x00

 

Different command lines always come up with the same error. 

 

O/S is Win7, nothing else extraordinary going on.

 

Many thanks for any useful tips!

This gets incredibly frustrating.  Apparently "avrdude: stk500_getsync<>: not in sync: resp=0x00" is all the response I will get from avrdude with ANY device, EVER.

 

I am trying at this point to get either of two USBASPs and an Arduino Uno and all combinations thereof to at least show a sig.

 

Going from the Uno to either USBASP #1 or #2, I use the command:

 

avrdude -c stk500v1 -p m8 -P com5 -b 19200 -v

 

and get the above error.  This used to work! frown

 

Going from USBASP#1 to USBASP #2 I use the command:

 

avrdude -c stk500v1 -p m8 -P com1 -v

 

I get the same error.

 

Going from usbasp #2 to usbasp #1 I get the same error.

 

Seriously, what's going on here?   O/S is Windows 7.   Nothing obviously strange anywhere.

 

Many thanks for any answers!

Does the target (Arduino Uno) have power on it?

Can you post a picture of your setup?

Go on. USBASP is a USB device. You do not give it baudrate or COM arguments.
Post a link to the actual USBASP that you have bought. A proper $3 Chinese dongle should work fine.
Quote the actual commandline. You will get proper advice.

OK, no COM arguments.  The baudrate was in the line for the Uno > usbasp.

Here's the new  usbasp #2, probably the most common one on the internet:

 

Here is usbasp #1 which you may recall our reflashing in an earlier chapter:

 

 

 

Here's the Uno/usbasp:

 

 

Which is wired to the usbasp like:

 

Arduino Pin Number

10 RESET

11 MOSI

12 MISO

13 SCK

GND GND

 

And 5V out for the VCC

Quote the actual command line.

 

For usbasp #2 into usbasp #1 (or vice-versa):

 

avrdude -c stk500v1 -p m8

 

OR

 

avrdude -c stk500v1 -p m8 -v

 

...both get the same concluding error:

 

avrdude: stk500_getsync<>: not in sync: resp=0x00

 

The Arduino Uno going into either usbasp #1 or #2 using the command line:

 

avrdude -c stk500v1 -p m8 -P com5 -b 19200 -v

 

...both get the same old, tiresome error

 

avrdude: stk500_getsync<>: not in sync: resp=0x00

 

The odd thing is that this worked previously.

Well, here's hoping.  Thanks!
