dhd_module_init: Failed to load the driver

[rageworx]

Looks dhd_wifi failure to load driver, as log :

Looks SDIO not configured ?

USB eth works well. WiFi not tested.

[rageworx]

checking rock960-model-ab-linux.dts,

 193     wireless-wlan {
 194         compatible = "wlan-platdata";
 195         rockchip,grf = <&grf>;
 196         wifi_chip_type = "ap6354";
 197         sdio_vref = <1800>;
 198         WIFI,host_wake_irq = <&gpio0 3 GPIO_ACTIVE_HIGH>;
 199         status = "okay";
 200     };

Seems fine.

[rageworx]

what IRQ of oob ?

 dhd_wlan_init_gpio: unknown oob irqflags !

[rageworx]

Maybe it belong to wrong dts. There's many wrong MIPI-CSI2 camera and ISP configuration on dts. Now it is testing to corrected dts.

[rageworx]

This is a bug as identified to reason driver not load from ext-4 file-system. Need exactly matched "dts" configuration for each different models of RK3399.

[ikalkov]

@rageworx, did you manage to fix this problem? I have a similar one.

[rageworx]

@ikalkov Sorry, I didn't advanced this issue for a while, by doing other project. This issue may solved by using different version of defconfig. I will check it further.

[rageworx]

@rageworx, did you manage to fix this problem? I have a similar one.

Dear @ikalkov, I'm on working kernel with gcc-8.3 for now. I will be in touch if to solve this issue.

[rageworx]

I will fix it soon, but now I'm on working for rk3588s. It will ve solved and share it.

This issue are occurs on different issue on Debian10.

Seems to related in rfkill_wifi or wlan logic ( segment fault )

[rageworx]

Plan to switching kernel version 5.10 ( as like rk3588/rk3588s )
