This repo provides packages for bringup of IPQ family chips. It produces a bootable kernel with built-in initramfs. The main use-case is integration of QCA's out-of-round kernel modules for networking. These are QCA-SSDK, QCA-NSS-DP; however some chips may require extra modules.
First, obtain an upstream buildroot tree. From the buildroot tree, configure using the BR2_EXTERNAL. Assuming that both buildroot and this repo are cloned in the same base directory, the following will suffice:
make BR2_EXTERNAL=../buildroot-external-ipq807x ipq807x_defconfig
The default configuration can now be customized with:
make nconfig
Start a build with:
make
A common use case is to make incremental changes to a package's source. To facilitate this, buildroot provides a way to manually specify the source directory for a package. This is done by editing a file named local.mk. Assuming linux is cloned in ../linux, and similarly for qca-ssdk, local.mk would have the following contents:
LINUX_OVERRIDE_SRCDIR = ../linux
QCA_SSDK_OVERRIDE_SRCDIR = ../qca-ssdk
At this point, the package may need to be rebuilt. Each package uses the
<pkg>-rebuild target. For example:
make linux-rebuild
make qca-ssdk-rebuild all
Note that the all target is optional. It tells buildroot to also re-assemble
an image after the package is rebuilt.
Call the <pkg>-rebuild target after a change is made to the sources. buildroot
uses rsync to update modified files.
Sometimes, buildroot's system may fail to correctly rebuild a package. This
usually manifests as source changes not reflecting in the behavior of said
package. In this case the <pkg>-dirclean target may help:
make qca-ssd-dirclean
make qca-ssdk-rebuild
