| U-Boot for the NXP i.MX8QM ROM 7720a1 board |
| =========================================== |
| |
| Quick Start |
| ----------- |
| |
| - Build the ARM Trusted firmware binary |
| - Get scfw_tcm.bin and ahab-container.img |
| - Get imx-mkimage |
| - Build U-Boot |
| - Build imx-mkimage |
| - Flash the binary into the SD card |
| - Boot |
| |
| Get and Build the ARM Trusted firmware |
| -------------------------------------- |
| |
| .. code-block:: bash |
| |
| $ 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 |
| |
| Get scfw_tcm.bin and ahab-container.img |
| --------------------------------------- |
| |
| .. code-block:: bash |
| |
| $ 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 |
| |
| Or use this to avoid running random scripts from the internet, |
| but note that you must agree to the license the script displays: |
| |
| .. code-block:: bash |
| |
| $ dd if=imx-sc-firmware-1.1.bin of=imx-sc-firmware-1.1.tar.bz2 bs=37185 skip=1 |
| $ tar -xf imx-sc-firmware-1.1.tar.bz2 |
| $ cp imx-sc-firmware-1.1/mx8qm-val-scfw-tcm.bin $(builddir) |
| |
| $ dd if=firmware-imx-8.0.bin of=firmware-imx-8.0.tar.bz2 bs=37180 skip=1 |
| $ tar -xf firmware-imx-8.0.tar.bz2 |
| $ cp firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img $(builddir) |
| |
| Build U-Boot |
| ------------ |
| |
| .. code-block:: bash |
| |
| $ export ATF_LOAD_ADDR=0x80000000 |
| $ export BL33_LOAD_ADDR=0x80020000 |
| $ make imx8qm_rom7720_a1_4G_defconfig |
| $ make u-boot.bin |
| $ make flash.bin |
| |
| Flash the binary into the SD card |
| --------------------------------- |
| |
| Burn the flash.bin binary to SD card offset 32KB: |
| |
| .. code-block:: bash |
| |
| $ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync |
| |
| Boot |
| ---- |
| |
| Set Boot switch SW2: 1100. |
