I did more of a dance with AI and eventually got it working.
This was the real repo: https://github.com/radxa-pkg/aic8800
Got the AI to write a summary of the dance.
Phase 1: Resolving the Tooling and Environment Dependencies
We started with a clean, lightweight system image missing common Linux development tools. We methodically installed the software compilation and packaging toolchain required to handle vendor drivers:
Kernel Headers: Replaced the generic linux-headers-$(uname -r) command with the specific architecture branch package (linux-headers-current-arm64) to give the driver access to the Linux kernel API blueprints.
Line Ending Conversions: Installed dos2unix to fix internal cross-platform formatting issues within the raw source files.
Packaging Toolchain: Installed devscripts, debhelper, and fakeroot to fulfill the minimum environment demands of the dpkg-buildpackage engine.
DKMS Engine Helpers: Installed dh-dkms to handle the missing modern virtual package mapping (dh-sequence-dkms).
Phase 2: Resolving Kernel Version API Incompatibilities
Because the hardware driver code was originally written for older Linux builds, trying to compile it directly against a modern 6.18 kernel threw standard compilation crashes. We bypassed the rigid Debian patch architecture and fixed the source code directly:
Signature Alignment: Modified the function argument signature for .get_tx_power in rwnx_main.c to support the newer 5-parameter layout required by the upstream kernel (struct wiphy *wiphy, struct wireless_dev *wdev, int bss_idx, unsigned int link_id, int *mbm).
Variable Alignment: Updated the interior variable name pointer within that function definition from dbm to mbm to match modern wireless power unit metrics used in current Linux network subsystems.
Phase 3: Bypassing Packaging & Direct Kernel Compilation
Rather than battling failing packaging lint tests or restrictive file verification scripts, we pivoted to an elegant, direct implementation:
Dropped straight into the target interface folder (src/USB/driver_fw/drivers/aic8800/).
Ran a direct raw build command targeting the standalone USB interface module flag: make CONFIG_AIC8800_USB=m.
Manually pushed the generated binaries directly into the system kernel storage directory tree using sudo make install and synchronized the dependency layout using depmod -a.
Phase 4: Correcting Firmware Pathing & Module Sequence
The driver successfully built and registered with the kernel, but the physical USB bus threw initialization timeouts (bus is not up=0). We fixed the underlying hardware communication pipeline:
Firmware Relocation: Traced the location of the compiled firmware folder hidden within the repository's package blueprints, and copied the raw firmware files directly into the absolute hardware search path at /lib/firmware/aic8800D80/.
Sequential Probing: Cleared out the broken module states and forced the hardware interface modules to load in their structural order—giving the hardware bus loader helper (aic_load_fw) a 2-second sleep window to awaken the USB links before initializing the operational wireless adapter engine (aic8800_fdrv).
