polarfire-soc-buildroot-sdk Release v2022.09
The memory map of fabric peripherals has changed & so the examples will not be backwards compatible with the v2022.05 release. The proxy dma example is not supported by the Linux kernel version used in the v2022.05 release.
There's been a slight change to the prerequisite packages, with u-boot-tools and kmod explicitly added. Recent docker containers for ubuntu no longer include the depmod utility with the existing set of requirements & modules failing to load (as they won't be present in the image) is the most obvious symptom. Installing the kmod package fixes this.
With the addition of remoteproc and an openSBI version bump, the HSS has grown too large for a single binary to support all of its features. The default HSS image in the Icicle Kit Reference Design does not enable QSPI support. Please take a look at the Booting from QSPI documentation for more information.
This will be the last release of the PolarFire SoC Buildroot SDK - support for buildroot will be in the Linux4Microchip buildroot external repo in the future.
