| GPIO mappings for Tegra2 Seaboard. |
| |
| From U-Boot you can read and write these GPIOs using the following commands. |
| |
| gpio input <port in decimal> <bit> |
| gpio output <port in decimal> <bit> <0|1> |
| |
| The rows with ??? at the end have not been tested yet. |
| The rows with !!! at the end have been tested but fail to behave as expected. |
