CAUTION
Type-C Port2 is the only power supply port, and it must be always supplied for system running.
i.MX 8M Mini 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 the Universal Serial Bus Power Delivery Specification Revision 2.0. There are two ways to avoid repower:
The power switch must always be at the ON side before adapting the PD
charger.
Change the software to disable the PD function, and make it Type-C supply
only.

Processor

The i.MX 8M Mini processors represent NXP Semiconductor’s latest achievement in the integrated multimedia-focused products offering high performance processing with a high degree of functional integration, targeted towards the growing market of connected devices. The i.MX 8M Mini processor features NXP’s advanced implementation of the Quad Arm Cortex®-A53+ Arm Cortex®-M4 core, which operates at speeds up to 1.8 GHz. Each processor provides a 32-bit DDR3L/DDR4/LPDDR4 memory interface and other interfaces for connecting peripherals, such as MIPI LCD, MIPI Camera, WLAN, Bluetooth™, Ethernet, Digital Mic, GPS, and multi-sensors.
For more detailed information about the processor, see the datasheet and reference manual on
www.nxp.com/i.MX8MMINI.

Boot Mode and Boot Device configurations

The i.MX 8M Mini Applications Processor 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 Mini can download a program image from a USB connection when configured in serial downloader mode. The method used to determine where the processor finds its boot information is from two dedicated BOOT MODE pins.
Table 2 shows the values used in the two methods.

It is important for the developer to remember that these two pins are tied to the BOOT modules. If the developer wants to boot the program Image from the Internal Boot mode, which means the processor will execute the boot code from the internal boot ROM, the position of the switch 1 and 2 must be set to OFF (0), ON (1), it is the same principle to choose the Serial Downloader mode or Boot from Fuse mode to load boot code into the processor.
If Internal Boot mode is selected, the developer can set the switches SW1101 and SW1102 to choose the boot device and related boot configurations as shown in Table 3 and Figure 4. Figure 5 shows the detailed connection of SW1101 and SW1102.
BOOT Device SW1101 SW1102
NOTE
SW1101 bit 3 and bit 4 are used for compatible design with i.MX 8M Nano, which must be set to 1 and 0 for i.MX 8M Mini.
SW1102 bit 10 is used for Infinit-Loop (Debug use only), which must be set to 0.
