Hi
 

I have been working on one off my projects. I created first on a testboard with some hardware my setup. I made my program in sx/B and after some succesful test I made my own circuit bord. I downloaded the same program as I used on my testboard  and everything is working fine. At that point I have still the sxkey connected and generating the clock (50MHz). When I now disconnect the sxkey and insert the resonator (50MHz) the program is running for about 20sec and then stops running. I also see that when I 'm running on the sxkey the whole curcuit is consuming +/- 100 mA. That is normal by my calculation. On the resonator I see that during the first 20 sec it is the same 100 mA. But then it is dropping to 40 mA.It seems like the sx48 is going to sleep but I did not program/want it. It is not going to sleep on the sxkey. If I give hime a reset It is back running for 20 sec.

I don't understand wy it is working with the sxkey and not with the resonator.

 

Some info

 

I use an sx48. 

Program in sx/B

resonator 50MHz.

 

Has someone a clue to what can cause this problem??

 

Thanks in advace
