| ## 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. |
