- 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.
- Reference Documentation
- ~~~~~~~~~~~~~~~~~~~~~~~
- Details on how to prepare, generate & deploy the boot image be found in following documents:
