- ===========================================
- 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.
