| NXP i.MX 9 Series |
| ================== |
| |
| Building on the market-proven i.MX 6 and i.MX 8 series, i.MX 9 series applications |
| processors bring together higher performance applications cores, an independent |
| MCU-like real-time domain, Energy Flex architecture, state-of-the-art security |
| with EdgeLock® secure enclave and dedicated multi-sensory data processing engines |
| (graphics, image, display, audio and voice). The i.MX 9 series, part of the EdgeVerse™ |
| edge computing platform, integrates hardware neural processing units across many |
| members of the series for acceleration of machine learning applications at the edge |
| `i.MX9 Applications Processors`_. |

| Boot Sequence |
| ------------- |
| |
| BootROM --> SPL --> BL31 --> BL33(u-boot) --> Linux kernel |
| |
| How to build |
| ------------ |
| |
| Build Procedure |
| ~~~~~~~~~~~~~~~ |
| |
| - Prepare AARCH64 toolchain. |
| |
| - Get the ELE FW image from NXP linux SDK package |
| |
| - Build SPL and u-boot firstly, and get binary images: u-boot-spl.bin, |
| u-boot.bin and dtb |
| |
| - Build TF-A |
| |
| Build bl31: |
| |
| .. code:: shell |
| |
| CROSS_COMPILE=aarch64-linux-gnu- make PLAT=<Target_SoC> bl31 |
| |
| Target_SoC should be "imx93" for i.MX93 SoC. |
| |
| Deploy TF-A Images |
| ~~~~~~~~~~~~~~~~~~ |
| |
| TF-A binary(bl31.bin), u-boot-spl.bin u-boot.bin, ELE FW image are combined |
| together to generate a binary file called flash.bin, the imx-mkimage tool is |
| used to generate flash.bin, and flash.bin needs to be flashed into SD card |
| with certain offset for BOOT ROM. |
