TOOLCHAIN PREREQUISITE
You must download the external Toolchain. NVIDIA does not distribute this toolchain.

BUILD
Set the appropriate paths for the below variables:
export SPE_FREERTOS_BSP=<path to root directory where rt-aux-cpu-demo-fsp, fsp and freertos source directories reside>
export CROSS_COMPILE=<path to installed cross compiler>/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-
cd ${SPE_FREERTOS_BSP}/rt-aux-cpu-demo-fsp
To build firmware for a specific platform
make bin_t23x
@note Build speed is significantly faster by using the `-j <jobs>` option with `make`.
For example, `make -j16 bin_t23x`.
## To build doxygen documents
Make sure you have doxygen installed on your computer. For Ubuntu systems:
sudo apt-get install doxygen
To generate the documents:
make docs
The output can be found at `out/docs`.
## To build everything
make
make all
The above commands build all the targets i.e. spe firmware binaries for all the
SOCs and Doxygen documents.
## Build artifacts
The built SPE firmware binary can be found at `out/<soc>/spe.bin`.
The doxygen build generates `out/docs/index.html` file. Open it
using a browser to navigate the documentation.
## To clean the build artifacts
Clean everything (documentation and firmware):
make clean
To clean t23x only firmware objects and build artifacts:
make clean_t23x
To clean only doxygen generated files:
make clean_docs
# FLASH
1. Back up the original `spe_t234.bin` located in the
following directory:
Linux_for_Tegra/bootloader/
2. Copy the generated `out/<soc>/spe.bin` to the following locating, depending on your target.
- For the T234 SoC, copy it to:
Linux_for_Tegra/bootloader/spe_t234.bin
The `Linux_for_Tegra` directory is part of the extracted L4T build that
you used to flash the Jetson device.
3. Use the command below to just flash only the spe-fw partition:
sudo ./flash.sh -k A_spe-fw <T234 SoC based Jetson platforms> internal ```
