power on boot

stef

Hi

I have succesfully created a program for an sx28. It is running very fine but I'm struggeling with one thing.

If I cut the power and reboot the SX28 by applying power it is not starting the program. It is hanging at that moment. When I just puch the resetbutten I have connected it is starting. (used a reset butten with a pull up resistor).

Does anyone has suggestions on what to modify to be able to start the complete program without user transaktion at power one??

Ps I tested my chip on the professional develpingboad and thier was no problem. Now I made my own pcb and everything is working exept the power one.

All suggestions are welcome.

Stef,
· Make sure you enable the "Brown Out Reset" on the DEVICE line.
· If you are running the SX from 5V then add BOR42 to the device line. See if that fixes it.

Hi Bean,

Thanks. I added the Bor42 in the device line and now I tested it.

Everything is working fine now.
