| U-Boot for the Toradex Apalis iMX8QM V1.0B Module |
| |
| Quick Start |
| =========== |
| |
| - Build the ARM trusted firmware binary |
| - Get scfw_tcm.bin and ahab-container.img |
| - Build U-Boot |
| - Load U-Boot binary using uuu |
| - Flash U-Boot binary into the eMMC |
| - Boot |
| |
| Get and Build the ARM Trusted Firmware |
| ====================================== |
| |
| $ git clone -b imx_4.14.78_1.0.0_ga https://source.codeaurora.org/external/imx/imx-atf |
| $ cd imx-atf/ |
| $ make PLAT=imx8qm bl31 |
| |
| Get scfw_tcm.bin and ahab-container.img |
| ======================================= |
| |
| $ wget https://github.com/toradex/meta-fsl-bsp-release/blob/toradex-sumo-4.14.78-1.0.0_ga-bringup/imx/meta-bsp/recipes-bsp/imx-sc-firmware/files/mx8qm-apalis-scfw-tcm.bin?raw=true |
| $ mv mx8qm-apalis-scfw-tcm.bin\?raw\=true mx8qm-apalis-scfw-tcm.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 |
| |
| Copy the following binaries to the U-Boot folder: |
| |
| $ cp imx-atf/build/imx8qm/release/bl31.bin . |
| $ cp u-boot/u-boot.bin . |
| |
| Copy the following firmware to the U-Boot folder: |
| |
| $ cp firmware-imx-8.0/firmware/seco/ahab-container.img . |
| |
| Build U-Boot |
| ============ |
| |
| $ make apalis-imx8qm_defconfig |
| $ make u-boot-dtb.imx |
| |
| Load the U-Boot Binary Using UUU |
| ================================ |
| |
| Get the latest version of the universal update utility (uuu) aka mfgtools 3.0: |
| |
| https://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fgithub.com%2FNXPmicro%2Fmfgtools%2Freleases |
| |
| Put the module into USB recovery aka serial downloader mode, connect USB device |
| to your host and execute uuu: |
| |
| sudo ./uuu u-boot/u-boot-dtb.imx |
| |
| Flash the U-Boot Binary into the eMMC |
| ===================================== |
| |
| Burn the u-boot-dtb.imx binary to the primary eMMC hardware boot area partition: |
| |
| load mmc 1:1 $loadaddr u-boot-dtb.imx |
| setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200 |
| mmc dev 0 1 |
| mmc write ${loadaddr} 0x0 ${blkcnt} |
| |
| Boot |
