peripherals, such as WLAN, Bluetooth™, GPS, displays, and camera sensors. Same as other i.MX processors, i.MX RT1050 also
has rich audio and video features, including LCD display, basic 2D graphics, camera interface, SPDIF and I2S audio interface.
The i.MX RT1050 applications processor can be used in areas such as industrial HMI, IoT, motor control and home appliances.
The architecture's flexibility enables it to be used in a wide variety of other general embedded applications too. The i.MX processor
provides all interfaces necessary to connect peripherals such as WLAN, Bluetooth™, GPS, camera sensors, and multiple displays.
For more detailed information about i.MX RT1050, see i.MX RT1050 Datasheet and Reference manual.
2.2 Boot mode configurations
The device has four boot modes (one is reserved for NXP use). The boot mode is selected based on the binary value stored in
the internal BOOT_MODE register. Switch (SW7-3 & SW7-4) is used to select the boot mode on the IMXRT1050 EVKB board.
Table 2. Boot mode pin settings
BOOT_MODE[1:0] (SW7-3 SW7-4) BOOT type
00 Boot From Fuses
01 Serial Downloader
10 Internal Boot
11 Reserved
Typically, the internal boot is selected for normal boot, which is configured by external BOOT_CFG GPIOs. Table 3 describes the
typical Boot mode and Boot device settings.

For more information about boot mode configuration, see the System Boot chapter in i.MX RT1050 Processor
Reference Manual (document IMXRT1050RM).

NOTE
2.3 Power tree
A DC 5 V external power supply is used to supply the IMXRT1050 EVKB Board at J2, and a slide switch SW1 is used to turn the
Power ON/OFF. J28 and J9 can also be used to supply the EVKB Board. Different power supply need to configure different Jumper
setting of J1. Table 4 describes the details.

Some computers’ USB cannot support 500 ma before establishing communication. In this case, it is recommended
to replace the computer or use the power adapter (J2) to power the EVKB board.
NOTE
Figure 5 shows the power tree.

Figure 6 shows the power control logic of the IMXRT1050 EVKB board.
• It will power up SNVS firstly, then PMIC_REQ_ON will be switched on to enable external DC/DC to power up other power
domains.
• ON/OFF button is used to switch ON/OFF PMIC_REQ_ON to control power modes.
• The RESET button and WDOG output are used to reset the system power.

1. For silicon A0, DCDC_IN voltage domain is 2.9 - 3.1 V.
2.4 SDRAM memory
One 256 Mb, 166 MHz SDRAM (MT48LC16M16A2B4-6AIT: G) is used on the EVK board.
2.5 SD card slot
There is a SD card slot (J20) on the IMXRT1050 EVKB Board. J20 is the Micro SD slot for USDHC1 interface. If the developer
wants to boot from the SD card, the boot device switch (SW7) settings should be: ON, OFF, ON, OFF, as shown in Table 3.
2.6 Hyper Flash
On the IMXRT1050 EVKB Board, there is one 512 Mbit Hyper Flash device. If the developer wants to boot from the Hyper Flash,
the boot device switch (SW7) settings should be: OFF. ON, ON, OFF, as shown in Table 3.
2.7 QSPI Flash
A 64Mbit QSPI Flash is used on the IMXRT1050 EVKB Board. If the developer wants to boot from the QSPI Flash, the boot device
switch(SW7) settings should be: OFF, OFF, ON, OFF, as shown in Table 3.
By default, this QSPI Flash is disabled on the EVKB. To enable the onboard QSPI Flash, the settings need to be changed.
1. Remove resistors R356 and R361 to R366.
2. Weld 0 Ω resistors: R153 to R158.
2.8 Ethernet connector
There is one Ethernet Mac controller in the MIMXRT1050 processor. The Ethernet subsystem of the IMXRT1050 EVKB board is

J12 is a 3.5 mm audio stereo headphone jack, which supports jack detect.
2.11 OpenSDA circuit (DAP-Link)
The OpenSDA circuit (CMSIS–DAP) is an open-standard serial and debug adapter. It bridges serial and debug communications
between a USB host and an embedded target processor.
CMSIS-DAP features a Mass Storage Device (MSD) bootloader, which provides a quick and easy mechanism for loading different
CMSIS-DAP Applications such as flash programmers, run-control debug interfaces, serial-to-USB converters, and more. Two or
more CMSIS-DAP applications can run simultaneously. For example, run-control debug application and serial-to-USB converter
