Tilt the
Board
• After the TWR-VF65GS10 module
powers up, the U boot bootloader will
load the out-of-box demo from the
SD card. The ARM Cortex-A5 core
runs the Linux
®
operating system and
uses the Open SDA USB-to-serial
bridge. The ARM Cortex-M4 core
runs the Freescale MQX™ operating
system and uses the TWR-SER or
TWR-SER2 serial module for serial
communication. Both operating
systems operate independently of each
other on their respective cores, but can
communicate via software APIs and
shared memory.
• Tilt the module to see different LEDs
light up—the accelerometer data is
being read by MQX on the M4 core
5
and transferred to Linux on the A5
core. You will also see Linux output on
the OpenSDA serial connection set up
in Step 3.

Start
Debugging
• To start debugging with DS-5,
the OpenSDA firmware needs to
be updated with the CMSIS-DAP
application. For more detail, please
refer to the “Jump Start Your
Design” documentation located at
