We have developed a hardware consisting of BF706 as the main controller. I am facing power issues with this. It is drawing more current. I am using only the SPORT of BG706 which is configured to operate with external clock and in TDMA mode. The external clock is 1MHz. Our application is running successfully on this h/w, but its drawing more current.
Thanks and Regards,
I suspect that the increased power you see is caused by the emulator setting clock frequencies when it connects according the values in the following file:
C:\Analog Devices\CrossCore Embedded Studio 2.1.0\System\ArchDef\ADSP-BF706-resets.xml
You can fix this by modifying the clocks settings in the file or by explicitly setting the CGU in your application. I recommend doing both to avoid confusion. If you followed the termination instructions in the data sheet Designer Quick Reference you should not have any floating inputs causing additional power consumption.
