Boot the board
Before booting with QNX OS, you'll have to first manually flash U-Boot to microSD card.
For more information, see Flash U-boot to SD card
After the target boots, you can run U-Boot commands to load QNX IFS and DTB from microSD card,
then use go
commands to Boot QNX OS.
After QNX OS starts, if you copy QNX IFS and DTB from microSD card and flash u-boot 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.

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.u-boot=> load mmc 1:1 0x80800000 ifs-imx93-phyboard-nash.raw 12936456 bytes read in 146 ms (84.5 MiB/s) u-boot=> load mmc 1:1 0x80600000 imx93-phyboard-nash.dtb 50254 bytes read in 5 ms (9.6 MiB/s) u-boot=> go 80800000 80600000 ## Starting application at 0x80800000 ... board_smp_num_cpu: 2 cores board_smp_num_cpu: 2 cores board_smp_num_cpu: 2 cores Welcome to QNX 8.0.0 on PHYTEC-phyBOARD-Nash-i.MX93 !

After you've booted your board using the microSD card, you can choose to prepare the eMMC to boot using the U-Boot and QNX IFS image. For more information, see
Boot from an eMMC memory device
