Ath9k: probe of 0000:01:00.0 failed with error -12

Installing and Using OpenWrt

Hello. I am trying to install a Qualcomm Atheros AR958x 802.11abgn Wireless Network Adapter on OpenWRT on a Raspberry Pi CM4 8GB. However, I'm getting the error "ath9k: probe of 0000:01:00.0 failed with error -12". What should I do? I request your help.

What kind of device is this exactly?
Did you buy it as a notebook spare or salvage it from there or did it come out of an old router/ AP?

Only the standalone cards (meant for PCs, notebooks) are equipped with the necessary EPROM for the wifi calibration data (ART). Cards destined for routers/ APs come 'usually' without this crucial EPROM, in favour of putting the data into a partition on the main system flash instead (which you won't have access to outside of its original environment).

EDIT: and with PC/ notebook cards, you are likely to hit ATH9K_SUPPORT_PCOEM (at least on non-x86).

This occurs when installing Dudlelab's NM-DB-3M communication module.

Any good solutions?

Raspberry CM4 is 64bit and requires AR958x 32bit storage. Configuring DMA solved the problem. Please note.
