[Jetson Nano / Kernel 4.9.337]: ieee80211_register_hw failed (-22)

[wizath]

Tried to use new v1.5 driver, but received kernel panic during loading new driver, removed ENABLE_DYNAMIC_PS that helped to load the driver properly when using v1.3.x, but no success. Any ideas?

[wizath]

It turns out that DCONFIG_MAC80211_MESH caused this error. Disabling it solves it

[pietertolsma]

@wizath how did you load the device trees for the Jetson? What device tree did you use?

CONFIG_MAC80211_MESH should be defined while building kernel to have mesh support enabled.
It doesn't look like CONFIG_MAC80211_MESH is defined while building 4.9 kernel.
It is correct that you will have to remove "-DCONFIG_MAC80211_MESH" and kernel configuration should be inherited by kernel config file.

Since the nrc driver building Makefile already includes kernel config by setting below line.
"include $(KDIR)/.config"

-DCONFIG_MAC80211_MESH should be removed in nrc Makefile.
