For some computers’ USB, it cannot support 500ma before establishing
communication. In this case, it is recommended to replace the computer or
use the power adapter(J2) to power the EVK Board.
The power tree is shown in the following figure.
Figure 4. Power Tree
The power control logic of the MIMXRT1050 EVK board is shown in the following figure:
For A0 silicon:
•It will power up SNVS and DCDC_IN together 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.
•RESET button and WDOG output are used to reset the system power.
For A1 silicon:
•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.
•RESET button and WDOG output are used to reset the system power.

Figure 5. Power Control Diagram
NOTE
Power Control Diagram described in MIMXRT1050 EVK Board is true for A0 silicon For A1
silicon, DCDC_IN is expected to be powered with other domains together.
In the other word, for A0 silicon the DCDC_IN is powered with LDO (Path 1). And for A1 silicon, it
is expected to be powered with DC/DC (Path 2).
For A0 silicon, please following above power logic as if not power the SNVS together with
DCDC_IN, the on chip DCDC module will not power up correctly.
The power rails on the board are shown in Table 5.

Stereo Codec, WM8960.The MIMXRT1050 EVK Board include one headphone interface (J12), one
onboard MIC (P1), two speaker interfaces (J16, J17), and the SPDIF interface (J14 & J18, DNP). J12 is
a 3.5mm 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 runs in parallel
to provide a virtual COM communication interface while allowing code debugging via CMSIS-DAP
with just single USB connection.
For the MIMXRT1050 EVK Board, J28 is the connector between the USB host and the target processor.
Jumper to serial downloader mode to use stable DAP-Link debugger function. If developer wants to
make OpenSDA going to the bootloader mode, J27 should jumper to 1-2, and press SW4 when power
on. Meanwhile, the OpenSDA supports drag/drop feature for U-Disk. First, use the seral downloader
mode and drag/drop the image file to U-Disk. Then select Hyper Flash as boot device and reset the
Board, the image will run.
2.12.JTAG Connector
J21 is a standard 20-pin/2.54mm Box Header Connector for JTAG. The pin definitions are shown in the
following figure. Support SWD by default.
