Pins-used-by-pi-desktop

In order to achieve reliable power control and RTC the following pins on Pi is used by Pi-desktop. Except the two pins of I2C, please do not use the other pins listed in the table,otherwise there may be a problem. And the I2C pin just can be used as I2C but can not be General IO.

GPIO Fuction on Pi-desktop Detials
GPIO6 Pin2 The state of Pi,was read by the MCU
GPIO13 Pin1 The pulse signal from MCU to Pi
GPIO17 RTC_INTn interrupt signal of RTC
GPIO2 RTC_SDA/MCU_SDA SDA for both RTC and MCU
GPIO3 RTC_SCL/MCU_SCL SCL for both RTC and MCU
GPIO26 INT_MCU A gpio connected to MCU(reserved)
GPIO19 NRST_MCU Rest of MCU
