NOTE
Type-C Port2 is the only power supply port, and it must be always supplied for system running.
i.MX 8M Nano EVK is not a typical use case of the PD device. It is supplied by the PD charger only, but with a
power switch. When the switch keeps OFF for more than 5.5 seconds after adapting the PD charger, the charger
(Source) will repower EVK (Sink) after the system initiates the PD software. See Section 6.5.7 in Universal Serial
Bus Specification Revision 2.0. There are two ways to avoid the repower:
• The power switch must always be in the ON position before attaching the PD charger.
• Change the software to disable the PD function, and make it Type-C supply only.
2.1 Processor
The i.MX 8M Nano applications processors represent NXP Semiconductor’s latest achievement in highly integrated multimediafocused products offering high performance processing. These applications processors can enable the growing market of smart,
secure, connected devices. The i.MX 8M Nano applications processors feature NXP’s advanced implementation of the Quad ARM
Cortex®-A53+ ARM Cortex®-M7 cores, which operate at speeds up to 1.5 GHz and 750 MHz respectively. Each i.MX 8M Nano
device provides a 16-bit DDR3L/DDR4/LPDDR4 memory interface and other interfaces for connecting peripherals, such as MIPI
LCD, MIPI Camera, WLAN, Bluetooth™, Ethernet, Digital Mic, and multi-sensors.
For more detailed information about the processor, see the datasheet and reference manual on i.MX 8M NANO.
2.2 Boot mode and boot device configurations
The i.MX 8M Nano implements a compressed boot mode decode with four BOOT_MODE pins. It can boot from the boot
configuration selected on SW1101 or from the boot configuration stored on the internal eFUSE. In addition, the i.MX 8M Nano
can download a program image from a USB connection when configured in the serial downloader mode. The method used to
determine where the processor finds its boot information is from four dedicated BOOT MODE pins.
