Install QNX IFS
To manually install QNX OS, you need to copy the QNX IFS image from the microSD card to the internal storage on the board (e.g.: eMMC).
Typically, the board comes pre-installed with U-Boot. If it doesn't, you'll have to first manually install U-Boot. Steps can be found at the following link: Yocto Recovery SD card (https://variwiki.com/index.php?title=Yocto_Recovery_SD_card&release=mx8mp-yocto-mickledore-6.1.36_2.1.0-v1.3) , which will flash the entire eMMC with U-Boot as a raw partition and ROOTFS in another partition. Copy the required files like DTB, required binaries to the external microSD card.
After the target boots, you can run U-Boot commands to load QNX IFS from microSD card,
load FDT file from on-board eMMC, then use boot
commands to Boot QNX OS.
After QNX OS starts, if you copy QNX IFS from microSD card to on-board eMMC, then after another reset, you can boot the QNX IFS from the on-board eMMC.
Note:
Utilities like fdisk and mkdosfs etc. need to be fetched from your QNX SDP installation.
- Insert the microSD card to your board and power up the board.
U-Boot should boot as seen from the output on your serial console.

Note:
If the user wants to have automatic boot through the internal emmc i.e. mmcdev 0, then perform the steps of formatting
the partition and copying the binaries to internal emmc as shown below. Remember to change the SW7 switch configuration
to eMMC position i.e. INT to boot from the DART-MX8M internal storage.
- After the board boots succesfully from the external MMC(microSD card), you need to format the emmc file system.
Use mkdosfs command to format the file system and mount both the mmcdev 0 and 1 using DOS filesystem. For example:
Starting shell ... $ mkdosfs /dev/emmc0t131 Format complete: FAT32 (4096-byte clusters), 15229884 kB available. $ mount -t dos /dev/sd0t11 /sd $ mount -t dos /dev/emmc0t131 /emmc - After that copy the required binaries from microSD card to emmc (internal). Use sync
to update filesystems to match cached data. Restart the board after removing the SD card from the board. Now the board will boot
automatically since mmcdev is first taken as 0 and mmdev=0 is emmc where images are copied. For example:
Once QNX OS is running, you can test it by executing any shell commands, or any commands residing within the OS image, such as uname, pidin, mount, etc.$ cp -R /sd/* /emmc/ $ sync $ shutdown U-Boot SPL 2023.04-lf_v2023.04_var02+gca1dfc1574a (Sep 12 2024 - 13:30:09 +0000) U-Boot SPL 2023.04-lf_v2023.04_var02+gca1dfc1574a (Sep 12 2024 - 13:30:09 +0000) SEC0: RNG instantiated Normal Boot Trying to boot from BOOTROM Boot Stage: Primary boot image offset 0x8000, pagesize 0x200, ivt offset 0x0 U-Boot 2023.04-lf_v2023.04_var02+gca1dfc1574a (Sep 12 2024 - 13:30:09 +0000) CPU: i.MX8MP[8] rev1.1 1800 MHz (running at 1200 MHz) CPU: Commercial temperature grade (0C to 95C) at 43C Reset cause: POR Model: Variscite DART-MX8M-PLUS 1.x on DT8MCustomBoard 2.0 and above DRAM: 4 GiB optee optee: OP-TEE api uid mismatch PTN5150: Vendor ID [0x3], Version ID [0x1], Addr [I2C1 0x3d] Core: 213 devices, 28 uclasses, devicetree: separate MMC: FSL_SDHC: 1, FSL_SDHC: 2 Loading Environment from MMC... *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial SEC0: RNG instantiated switch to partitions #0, OK mmc2(part 0) is current device Part number: VSM-DT8MP-302 Assembly: AS310210259 Production date: 2024 Feb 11 Serial Number: f8:dc:7a:d4:75:3a SOM revision: 1.3 flash target is MMC:2 Net: Get shared mii bus on ethernet@30be0000 ADIN1300 PHY detected at addr 1 eth1: ethernet@30be0000, eth0: ethernet@30bf0000 [PRIME] Fastboot: Normal Normal Boot Hit any key to stop autoboot: 0 Running BSP bootcmd ... switch to partitions #0, OK mmc2(part 0) is current device 1693 bytes read in 2 ms (826.2 KiB/s) Running bootscript from mmc ... ## Executing script at 40480000 dwceqos_macaddr=f8 dc 7a d4 75 3a 14273812 bytes read in 45 ms (302.5 MiB/s) 63736 bytes read in 2 ms (30.4 MiB/s) Working FDT set to c0000000 ## Starting application at 0x40800000 ...
