Flashing Zircon on eMMC:
The board will boot out of eMMC by default. In order to boot Zircon, a custom u-boot binary is needed. The binary can be found at: go/imx8m-bootloader
First step involves flashing the board with the custom u-boot binary:
Requirements:
- Linux Host Machine
- For serial console: connect USB from your host to the Micro USB port on the board
- For fastboot: connect USB cable from your host to the USB-C port on the board
Create a file under /etc/udev/rules.d/70-nxp.rules with the following content:
SUBSYSTEM==”usb”, ATTR{idVendor}==”0525”, MODE=”0664”, GROUP=”plugdev”, TAG+=”uaccess”
From Device (iMX8 EVK):
- Reboot board and in serial console press space to halt autoboot
- From u-boot command line do the following:
- fastboot 0
From Linux Host:
- fastboot flash bootloader0 /PATH/TO/CUSTOM/UBOOT/u-boot.imx
fastboot reboot
If successful, the new U-Boot prompt should be “zircon-u-boot=>”
Once the custom U-Boot has been flashed, perform the following:
- Reboot board and press space to halt autoboot
- From u-boot command line do the following:
- fastboot 0
From the host side, go to your zircon repository and run the following command:
- ./scripts/flash-nxp
If successful, the board will reboot into Zircon.
