Please find the error screen short and suggest me why it's happen and what is solution? 

As suggested in the error did you try checking the connections as most of the time such errors are due to loose connections! 

yes connection is fine!

Could you post a pic of your USBASP or any link to the USBASP?

Almost all the USBASP can set the sck period automatically! Are you using first fischl.de firmware?

find screen short

Looks like you have to connect or put a jumper between the two headers near to the crystal that should do the job...your USBAsp require manual setting of sck period

no i checked all pin configuration all are fine.

now i have new problem. safe menu my displaying non of key are not working. now what should i do?

I meant this!

Could you be a bit clear i didn't get you!!?

mean both pin should directly connect to each other?

Yes by connecting these two you are changing the sck period(which is you're error!) and it will do the job!!

You could also try flashing your kk2.1 with arduino!

no after connect both pin full screen got blank and same error coming.

Then you need to update your USBASP firmware...better option would be updating your kk2.1 with arduino!

now kk 2.1 board non off keys are not working. only safe menu is displaying.

Here's a link for updating kk2.1 with arduino:

If you want to update your USBasp follow this:

now only safe menu is displaying and non of keys are not work?

You mean the kk 2.1 is unresponsive?
Did you disconnect the power supply and reconnect it and then try?
Try updating firmware using an arduino!

yes i try but it not responding and right now i dont have arduino board. I think this gone.

I don't think you have lost your board it may have caused a reset of the mcu.....i think you should give a try with an arduino after you get it!!

The SCK period issue is non-critical, I get it all the time. I see you are using a 10 pin cable with your USBASP so you could try again with a 10-6 pin adapter or you could check the kk 2.1 and USBASP pinouts to see that it has been plugged the right way.

I am get device signature error. Any can tell me what is device signature for KK 2.1?
