Verdin iMX8M Plus Module

Quick Start

  • Build the ARM trusted firmware binary

  • Get the DDR firmware

  • Build U-Boot

  • Flash to eMMC

  • Boot

Get and Build the ARM Trusted Firmware (Trusted Firmware A)

$ echo "Downloading and building TF-A..."
$ git clone
$ cd trusted-firmware-a

Then build ATF (TF-A):

$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make PLAT=imx8mp IMX_BOOT_UART_BASE=0x30880000 bl31
$ cp build/imx8mp/release/bl31.bin ../

Get the DDR Firmware

$ cd ..
$ wget
$ chmod +x firmware-imx-8.10.1.bin
$ ./firmware-imx-8.10.1.bin
$ cp firmware-imx-8.10.1/firmware/ddr/synopsys/lpddr4*_202006.bin ./

Build U-Boot

$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make verdin-imx8mp_defconfig
$ make

Flash to eMMC

> tftpboot ${loadaddr} flash.bin
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
> mmc dev 2 1 && mmc write ${loadaddr} 0x0 ${blkcnt}

As a convenience, instead of the last two commands one may also use the update U-Boot wrapper:

> run update_uboot


ATF, U-Boot proper and u-boot.dtb images are packed into FIT image, which is loaded and parsed by SPL.

Boot sequence is:

  • SPL —> ATF (TF-A) —> U-Boot proper
