Boot the board

After you transfer the image to an SD card, you can use it to boot your board.

After you boot your board, you can configure the eMMC or xSPI NOR flash memory to boot QNX OS. Whether you boot your board using the SD card, eMMC, or xSPI NOR flash memory, you should see something like the following in your console connection to the board after you press the SW3 button. If you're booting from the SD card, press the M key on your keyboard. Here's an example of what you should see in the console connection:

QNX OS should now be running on your target. You can test it by executing any shell command, or any command residing within the OS image (ls, pidin, etc.). You can also type uname and it should return QNX.

After you've booted your board using the SD card, you can choose to prepare the eMMC or xSPI NOR flash memory to boot using the QNX IPL and QNX IFS image. For more information, see Boot from an eMMC memory device and Boot using xSPI NOR flash.
