In Linux or android systems, if we want to configure the gpio pin of the feisikar imx6 processor, for example, the gpio_19 pin, we should look like this:
#define MX6Q_PAD_GPIO_19__GPIO_4_5\(_MX6Q_PAD_GPIO_19__GPIO_4_5 | MUX_PAD_CTRL(NO_PAD_CTRL))
_ Mx6q_pad_gpio_1920.gpio_4_5 is defined:

Baidu later found that the U disk in the arm of Linux needs to be manually mounted. Here's how:1, the USB stick will be inserted after the information displayed in t
