I'm trying to get a QCN9074-based AX Wifi transceiver working with a Pi 5. I've connected it via a Mini PCIe hat. I'm using an adapter board on that hat and externally powering the transceiver.
With Raspbian, the ath11k drivers are not built with the kernel. I have compiled the latest kernel and enabled the driver. I do see the device via lspci and see that the ath11k driver tries to load.
lspci -k:However, the driver is not loading properly. I see the following error:
dmesg | grep ath11:I have tried using dtparam=pciex1, dtparam=pciex1_gen=3, and dyoverlay=pciex1-compat-pi5,no-mip to no avail.
I'm hoping someone can point me in the right direction on what to do or take a look at next. Is this solved by some device tree overly? Are there some kernel configs I'm missing? Could it be the mini pcie hat? The fact it is detected via lspci has me hoping this can be resolved.
