3 years ago We discontinued support for modules with BRCM radios in 2019, and aren't planning to continue to add support for these radios going forward unless there is very compelling business value.
We hear from software developers in the community that brcmfmac support is working in linux mainline. You may want to try it out.
imx7d+brcm - wifi and bt are not working in Zeus 5.4.y Despite setting WIFI_MODULE=brcm, the compiled device tree has QCA extension! During boot, wifi test is failed and HW is not booted; I have bypassed the test and brought the HW up, but have no wifi/bt; all the needed files are there:
