QNX SDP 7.1 BSP release for Nitrogen8M Plus SMARC QNX SDP 7.1 BSP release for Nitrogen8M Plus SMARC We are proud to present our latest QNX SDP 7.1 BSP for our Nitrogen8M Plus SMARC board. For the impatient You can download the BSP below: BSP_boundary-imx8mp-nitrogen-smarc-sdp710-jbn7-v1.0.zip If you wish to test a pre-built binary before checking the BSP source code, here it is: BSP_boundary-imx8mp-nitrogen-smarc-sdp710-jbn7-v1.0.img.gz 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_boundary-imx8mp-nitrogen-smarc-sdp710-jbn7-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 QNX7.1. 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 called dwc0 # ifconfig dwc0 dwc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 capabilities=1f<IP4CSUM,TCP4CSUM,UDP4CSUM,TCP6CSUM,UDP6CSUM> enabled=0 address: 00:19:b8:0e:d1:c5 media: Ethernet autoselect (1000baseT full-duplex,flowcontrol) status: active inet 192.168.1.187 netmask 0xffffff00 broadcast 192.168.1.255 inet6 fe80::219:b8ff:fe0e:d1c5%dwc0 prefixlen 64 scopeid 0x11 # ping google.com PING google.com (142.250.178.142): 56 data bytes 64 bytes from 142.250.178.142: icmp_seq=0 ttl=116 time=4 ms 64 bytes from 142.250.178.142: icmp_seq=1 ttl=116 time=5 ms 64 bytes from 142.250.178.142: icmp_seq=2 ttl=116 time=4 ms 64 bytes from 142.250.178.142: icmp_seq=3 ttl=116 time=4 ms ----google.com PING Statistics---- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 4/4/5 ms variance = 3 ms^2 ETH1 interface is called fec0 # SOCK=/alt ifconfig fec0 fec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 address: 00:19:b8:0e:d1:c4 media: Ethernet autoselect (1000baseT full-duplex,flowcontrol) status: active inet 192.168.1.188 netmask 0xffffff00 broadcast 192.168.1.255 inet6 fe80::219:b8ff:fe0e:d1c4%fec0 prefixlen 64 scopeid 0x11 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/emmc5 /dev/sd0 /dev/emmc0t131 /dev/emmc3 /dev/emmc6 /dev/sd0t11 /dev/emmc1 /dev/emmc4 /dev/emmc7 # mount -t dos -o exe=all /dev/sd0t11 /mnt/ # ls -l /mnt/ total 41673 -rwxrwxrwx 1 root root 199 Mar 11 2024 boot.scr -rwxrwxrwx 1 root root 21335588 Mar 11 2024 qnx-ifs 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/ song.wav Audio support This BSP includes support for our WM8962 codec which can be used as follows: # wave /mnt/song.wav You can control the volume thanks to the mix_ctl tool: # mix_ctl group "Headphone",0 mute=on 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 # ls /dev/i2c* /dev/i2c1 /dev/i2c2 /dev/i2c3 /dev/i2c4 /dev/i2c6 # ls /dev/spi* /dev/spi1 /dev/spi2 All the above nodes can be accessed from your application using QNX API: UART API I2C API SPI 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 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 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 NOTICE: BL31: Built : 11:27:11, May 24 2022 Welcome to QNX Neutrino IPL for Boundary Devices Nitrogen8MP SMARC ATF commit: 47baad8 Command: Press 'D' for serial download, using the 'sendnto' utility Press 'M' for SDMMC download, IFS filename MUST be 'QNX-IFS'.
