For several months now, Linaro has been working together with HiSilicon to provide the community with access to source code for the Poplar board. This week an initial drop of source code for the Poplar board, along with flashing tools and some documentation will be made available on GitHub.
The initial code drop will include source for ARM Trusted Firmware, U-Boot, and a 4.11 based upstream kernel along with documentation on how to build the software and tools to flash it to the Poplar board.
This release of source code, tools and documentation provides:
* The ability to boot in 64-bit mode.
* Console functionality via the micro USB port.
* Network via ethernet.
* All cores enabled.
* USB device support (disk & network adapter)
* The ability to flash the board via USB flash drive.
This drop of source code is just a start. This code allows us to boot to a console using the source code and tools provided. We have begun to upstream this source and will continue to add features and update the repositories on a more regular basis. The team's goal is to release source as functionality is completed, tested and passes an internal IP review.
There is still more more to do with the bootloaders and partitioning of the eMMC which we will work on over the next couple of months. Kernel features due for release in the next month are HDMI support, and keyboard/mouse support.
We are also planning to provide a branch in the kernel tree that will be based on the Android 4.9 common kernel. This won’t be upstream based, but will be more feature complete than our mainline branch. This will be used to support AOSP running on the Poplar board.
As we push topics and changes to the GitHub repositories, we will post a message to the forums to update people here. I will provide another update on our overall progress and plans in early June.
