Banana Pi BPI-F3
================
Building
~~~~~~~~
1. Install the SpacemiT riscv cross compile toolchain_, or skip it if riscv toolchain is installed.
.. _toolchain: https://archive.spacemit.com/toolchain/
2. Setup cross compilation environment variable:
.. code-block:: console
export CROSS_COMPILE=<riscv64 toolchain prefix, e.g /opt/spacemit/bin/riscv64-unknown-linux-gnu->
3. Before building U-Boot, OpenSBI should be built first. OpenSBI can be
built for SpacemiT K1 SoC as below:
.. code-block:: console
git clone https://github.com/cyyself/opensbi -b k1-opensbi
cd opensbi
make PLATFORM=generic
4. Then build U-Boot as following:
.. code-block:: console
cd <U-Boot-dir>
make bananapi-f3_defconfig
make OPENSBI=<OpenSBI-dir>/build/platform/generic/firmware/fw_dynamic.bin
This will generate u-boot.itb
Burning
~~~~~~~
Actually, we can replace the uboot partition of Bianbu Linux which is the bsp_ to validate this patch,
use `balena etcher` to burn the bianbu-minimal.img to the sd card,
and replace the /dev/sdx4 where places the uboot_ with the `u-boot.itb` generated from this patch.
Or use fastboot:
Collect FSBL.bin, u-boot.itb, partition_2M.json, bootinfo_spinor.bin
u-boot-env-default.bin, fw_dynamic.itb from vendor SDK
.. code-block:: console
fastboot stage FSBL.bin
fastboot continue
fastboot stage u-boot.itb-vendor # the itb from vendor uboot
fastboot continue
fastboot flash mtd partition_2M.json
fastboot flash bootinfo bootinfo_spinor.bin
fastboot flash fsbl FSBL.bin
fastboot flash env u-boot-env-default.bin
fastboot flash opensbi fw_dynamic.itb
fastboot flash uboot u-boot.itb-mainline # the itb from mainline uboot
