![]() Current setup instructions for i.MX8QM MEK board include somewhat conflicting instructions, so here's an attempt to fix it. After trying both sets of firmwares, I can conclude that both of them fail to work: - no boot at all with imx-sc-firmware-0.7 / firmware-imx-7.6 - partial success with imx-sc-firmware-1.1 / firmware-imx-8.0: U-Boot 2021.04-rc3-00135-ge0669a43c8 (Mar 08 2021 - 16:49:08 +0200) CPU: NXP i.MX8QM RevB A53 at 1200 MHz Model: Freescale i.MX8QM MEK Board: iMX8QM MEK mu_hal_receivemsg timeout Build: SCFW 65afe5f6, SECO-FW 65afe5f6, ATF a-20190 mu_hal_receivemsg timeout sc_misc_get_boot_dev: res:16 Boot: SD0 DRAM: mu_hal_sendmsg timeout sc_rm_is_memreg_owned: mr:0 res:21 ...

U-Boot for the NXP i.MX8QM EVK board Quick Start =========== - Build the ARM Trusted firmware binary - Get scfw_tcm.bin and ahab-container.img - Build U-Boot - Flash the binary into the SD card - Boot Get and Build the ARM Trusted firmware ====================================== $ git clone https://source.codeaurora.org/external/imx/imx-atf $ cd imx-atf/ $ git checkout origin/imx_4.14.78_1.0.0_ga -b imx_4.14.78_1.0.0_ga $ make PLAT=imx8qm bl31 And copy the resulting bl31.bin to u-boot directory: $ cp build/imx8qm/release/bl31.bin path/to/u-boot/ Get scfw_tcm.bin and ahab-container.img ======================================= $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.1.bin $ chmod +x imx-sc-firmware-1.1.bin $ ./imx-sc-firmware-1.1.bin $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin $ chmod +x firmware-imx-8.0.bin $ ./firmware-imx-8.0.bin And copy the following firmwares to U-Boot folder: * `imx-sc-firmware-1.1/mx8qm-mek-scfw-tcm.bin` * `firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img` Build U-Boot ============ $ make imx8qm_mek_defconfig $ make flash.bin Flash the binary into the SD card ================================= Burn the flash.bin binary to SD card offset 32KB: $ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 Boot ==== Set Boot switch SW2: 001100.
