BitBake recipes to build Linux for various Trenz Electronic boards. NOTE: this is not an official repository.
The following boards are currently supported and are the machine names that should be used in the local.conf file:
- te0820-03-03eg
This package will update patch U-Boot to support the boards and also provide a device tree containing the hardware components found on the board.
This layer depends on:
| URI | Layers | Branch |
|---|---|---|
| git://git.openembedded.org/bitbake | thud | |
| git://git.openembedded.org/openembedded-core | meta | thud |
| git://git.yoctoproject.org/meta | meta | thud |
| https://github.com/Xilinx/meta-xilinx.git | meta-xilinx | rel-v2019.1 |
| https://github.com/Xilinx/meta-xilinx-tools.git | meta-xilinx-tools | rel-v2019.1 |
The machine configuration files add the following line:
IMAGE_INSTALL_append = " haveged"
This will ensure that the SSH server will startup in a timely manner by providing high entropy for random number generation quicker. Care should be taken to ensure this is acceptable for the security posture of the desired system.
To add additional boards, perform the following steps:
- Create the machine configuration file in /conf/machine
- Build a minimal design in Vivado and export the HDF file.
- Add the device tree to the /recipes-bsp/device-tree recipe.
- Add the exported HDF file to the /recipes-bsp/hdf recipe.
- Extract the platform init files from the HDF file and add them to the /recipes-bsp/platform-init recipe.
- Add the u-boot configuration file to the /recipes-bsp/u-boot recipe.
