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.
For information, see the steps in Use recovery mode to load the Toradex Easy Installer
and Use TEZI to install image
to install a Toradex Embedded Linux image in which U-Boot is included.
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 go
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.
- 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.

and the eMMC partitions, then copy the QNX IFS from the microSD card to on-board eMMC:
After you reset your board, you can load the QNX IFS from the on-board eMMC rather than the microSD card. You can use the following U-Boot commands to load and boot the QNX IFS from the eMMC:# mount -t dos /dev/sd0t12 /sd # mount -t dos /dev/emmc0t12 /emmc # cp /sd/ifs-imx8mp-verdin.bin /emmc/ # umount /sd # umount /emmc # shutdownVerdin iMX8MP # fatload mmc 1:1 0x40800000 ifs-imx8mp-verdin.bin Verdin iMX8MP # fatload mmc 2:1 ${fdt_addr_r} imx8mp-verdin-wifi-dahlia.dtb ...
