The GPIO numbers in the table below are relevant to how the Linux references these numbers. The CPU documentation refers to bank and IO while Linux flattens this out to one number space.
Pins #224 and above are from the perspective of the FPGA rather than the CPU. For example, toggling the IO #224 is ttymxc2_rxd which does not toggle the cpu's uart pin, but the FPGA IO directed at that pin in the CPU. Many of these UART pins are not set as GPIO by default, and the FPGA includes its own crossbar. The UART pins will be mapped to cpu or fpga uarts.

- ↑ The pad name does not often correspond with the functionality of the IO we use, but can be used to reference the pad in the CPU manual.
- ↑ This does not contain all of the functions possible for a pin, but the common functions as they are used on our off the shelf basebords. Consult the i.MX6 CPU Reference manual for a complete list.
- ↑ This pin is routed through the FPGA Crossbar
