Hi,
Can you please help answer the questions below regarding the AM335x pin muxing:
I am confused regarding pin assignments with the AM335X. I want to use Non-multiplexed mode with the address and data lines on the AM3352. But certain pins, such as address A3 for example are available on two different pins.
The following shots (attached) are from the AM335X TI Pin Muxing Tool.
Notice below GPMC A1 MUX 0 and GPMC A16 MUX0. These are the same pin, but the device muxes A0 and A16 on the same pin.

Now, notice GPMC_A0_MUX1.

I can’t find any documentation showing what MUX0 and MUX1 mean. Maybe they are just labels. Since I am using Non-multiplexed mode I am wondering which sets of pins I should use for the address bus. Maybe it doesn’t matter, but I want to choose the set that will work or make more sense. I am intending on using a 16 bit SRAM like device and a 16 bit NAND FLASH on the same bus.
Thanks,
Andrea
