Uploading Program to my Axon

[Hanoush]

My Axon was working fine but suddenly I was uploading a program using bootloader and it says "verify failed"
and I tried to restart axon,computer,checked my connections and also tried uploading another hex file but nothing worked.any idea ?

Admin,need your help ! this is my 2nd Axon

[Admin]

You need to tell us more information, such as battery checked, setup, etc.

Try uploading one of the demo programs (which other hex file did you try?).

[Hanoush]

I am using a DC Power supply 7.2V,I tried to upload another hex file that I know it works but failed also in verifying it. Today I will try Axon on another computer to make sure that this error is from Axon.

I tried it on another computer but didn't work also. but thanks god my old Axon got fixed 

[Admin]

So whatever happened to your old Axon?

(I try to track all Axon issues)

By any chance was it the same thing?

[Hanoush]

No,it isn't. the computer wasn't able to recogonize my old axon and with the new the I cann't upload the program.
