QNX SDP 8.0 BSP release for Nitrogen8M Plus SMARC
QNX SDP 8.0 BSP release for Nitrogen8M Plus SMARC
We are proud to present our latest QNX SDP 8.0 BSP for our Nitrogen8M Plus SMARC board.
For the impatient
You can download the BSP below:
If you wish to test a pre-built binary before checking the BSP source code, here it is:
This latter can be programmed in different ways:
- One can follow our programming eMMC guide
- One can use Balena Etcher to program its SD card or USB drive
- Linux users can also program it to SD Card or USB Stick using zcat and dd:
~$ zcat BSP_ezurio-nitrogen8mp-smarc_br-hw-rel_be-800-v1.0.img.gz | sudo dd of=/dev/sdX bs=1M
We also recommend reading our QNX Getting Started Guide article to learn about building/debugging QNX apps. Although this article has been written for QNX6.6, the info still applies for QNX8.0.
Nitrogen8M Plus SMARC BSP features
This section will detail all the currently supported features of the BSP.
Display support
The BSP supports both LVDS and HDMI output which can be tested using the OpenGL-ES gears
demo application.
Here is an example for HDMI:
# gles2-gears -display=3
300 frames in 5.004 seconds = 59.952 FPS
During that test, your display should look like below:
If you want to use the LVDS output, you need either our BD070LIC3 or BD101LIC3 LVDS display:
# gles2-gears -display=2
297 frames in 5.002 seconds = 59.376 FPS
Network support
Both gigabit Ethernet ports (ETH0
& ETH1
) are supported:
ETH0
interface is calleddwceqos0
# ifconfig dwceqos0

SD / eMMC support
Both SD card (on carrier board) and eMMC (on module) are supported:
# ls /dev/sd* /dev/emmc*
/dev/emmc0 /dev/emmc2 /dev/emmc6
/dev/emmc0t12 /dev/emmc3 /dev/emmc7
/dev/emmc0t179 /dev/emmc4 /dev/sd0
/dev/emmc1 /dev/emmc5 /dev/sd0t131
# mount -t dos -o exe=all /dev/emmc0t12 /emmc-fat/
# ls -l /emmc-fat/
total 13368
-rwxrwxrwx 1 root root 275 2024-10-15 16:34 boot.scr
-rwxrwxrwx 1 root root 49411 2024-10-17 14:38 imx-dtb
-rwxrwxrwx 1 root root 13639372 2024-10-17 15:07 qnx-ifs
The QNX6 partition is mounted automatically at bootup:
# mount
/dev/emmc0t179 on / type qnx6
ifs on / type ifs
/dev/shmem on /dev/shmem type shmem
USB Host support
All the USB Host ports of the Nitrogen8M Plus SMARC device are supported.
# ls /dev/umass0*
/dev/umass0 /dev/umass0t131
# mount -t dos -o exe=all /dev/umass0t131 /mnt
# ls /mnt/

GPIO / UART / I2C / SPI support
The BSP does support all the standard embedded IPs such as UART / I2C / SPI / GPIO of the i.MX 8M Plus.
Here is a list of the exposed IPs:
# ls /dev/ser*
/dev/ser1 /dev/ser2 /dev/ser3
# ls /dev/i2c*
/dev/i2c2 /dev/i2c3 /dev/i2c4 /dev/i2c6
# ls /dev/io-spi/
spi1 spi2
All the above nodes can be accessed from your application using QNX API:
The GPIO node however should be used via the gpio-test
binary:
# use gpio-test
gpio-test - Utility for the GPIO Resource Manager
Usage:
gpio-test -b bank -p pin [options]
Note:
- This utility does *not* configure the IOMUXC.
The IOMUXC pin muxing may need to be configured separately.
Options:
-b bank Set the GPIO bank number
-p pin Set the GPIO pin number being accessed
-i Configure the specified GPIO pin as an input
-o state Configure the specified GPIO pin as output and set its state
-w state Set the output state of the specified GPIO pin
-N path Specify the location of the GPIO resource manger to attach to
The default path is /dev/gpio
CAN support
The BSP includes the CAN driver for the i.MX 8MP that can be used with canctl
:
# canctl -u1,rx0 -i
Message queue size: 100
Wait queue size: 16
Mode: IO
Bitrate: 250000 Baud
Bitrate prescaler: 20
Sync jump width: 1
Time segment 1: 8
Time segment 2: 2
TX mailboxes: 32
RX mailboxes: 32
Loopback: NONE
Autobus: OFF
Silent mode: OFF
# canctl -u1,rx0 -M
GET_MID = 0x100C0000
# canctl -u1,rx0 -M
GET_MID = 0x100C0000
# canctl -u1,rx0 -r
READ_CANMSG_EXT 1:
mid = 0x100C0000
timestamp = 0xC25A
dat len = 4
dat = de ad be ef
....
# echo test > /dev/can1/tx32
IPL bootloader
Our BSP currently works if U-Boot is your main bootloader. U-Boot offers many features like boot from network, USB, display splash screen etc… However, U-Boot is GPL licensed, which can be inconvenient for some customers.
That is why we offer IPL support, for modules with 2GB or 4GB of LPDDR4, which allows to boot from either SD or eMMC.
You can flash it using fastboot
:
fastboot flash bootloader images/ipl-nitrogen8mp-smarc.imx
Then the boot log should look like the following:
Boot device: eMMC chip
NOTICE: BL31: v2.6(release):lf-5.15.32-2.0.0-rc1-0-g47baad824-dirty

QNX Momentics IDE integration
This BSP can be imported by the QNX Momentics IDE:
Then the BSP can be modified and built as needed:
Finally, the IDE brings many tools that can be used to profile the system while it is running:
DDR variants
This BSP can be built for Nitrogen8MP SMARC platforms with either 2GB or 4GB of LPDDR4.
By default, the build considers 2GB of LPDDR4, in order to change to 4GB you need to set an environment variable to build the BSP:
$ source /opt/qnx800/qnxsdp-env.sh
$ DDR_SIZE=4096 make
Or if you use the IDE, you can add a build variable in the project properties as shown below:
