APM 2.5.2 error - No Dataflash Inserted

Posted by criro1999 on July 20, 2014 at 6:11pm

I did notice next error (No Dataflash inserted) with my 3DR APM2.5.2 when loading an Arducopter firmware.

I did reset and erase the APM multiple times, same error. It looks to respond to all testing, but not sure if is safe to fly with this APM.

When I load an Arduplane FW, I do not see that error (see below right side). Loading again the Arducopter, the error is shown again (left side).

What could be the cause, what means and if I can fly safe?

Thanks, Chris

    Thank for info.
    
    I was able to locate the issue on my board. It looks the dataflash chip has some cold solder.
    
    When I press with thumb the dataflash chip and connect using the usb, then error dissapear, see below second connection.
    
    Any idea how to fix that?

        I was able to fix it myself.
        
        I used a different solder tip and a good magnifier and able to fix by melting soldering at each of 8 pins.
        
        Thanks again Richard for pointing me to that good information.
