[beagleboard] BeagleBone Black eMMC Conflict Pins

The schematic shows which pins are used for the eMMC. The schematic reflects what is on the PCB.

Next week I will check the SRM tables and look for any confusion and make all necessary corrections that I find…

Gerald,

Does this mean that P8 pins 3-6 and 20-25 cannot be used on the BeagleBone Black if we use the eMMC? I’m currently using these pins as GPIO…

Thanks,

That is what it means. The idea is that If you can hold off using those pins until the SW can reset the eMMC, meaning no signals applied to any pin, then you can use them after the eMMC is put into reset. That also means you must boot from uSD.

Gerald,

OK makes sense, thanks.
