EPC-R7200 UIO 中的 uIO_GPIO11、uIO_GPIO12如下
這兩根由uIO_ID_SW控制，pull high則使用uIO_GPIO11_I2C/uIO_GPIO12_I2C, pull則使用GPIO_SCL/GPIO_SDA
]
在TX2中
P0_0~P1_7對應的GPIO為 240~255 (新版本硬體)
ubuntu@localhost:~$ sudo cat /sys/kernel/debug/gpio gpiochip2: GPIOs 240-255, parent: i2c/7-0021, tca6416, can sleep:
PS : 舊版本硬體的GPIO11/GPIO12之GPIO為476/278
