I would like to enable the wifi/bt chip on Tanix TX5 MAX

 

I am running armbian 20.10 with 5.90 kernel with the meson-g12a-tanix-tx5max.dtb

The system does see the wifi chip, but it is not working / not listed in ifconfig as wlan0

dmesg output:

I have firmware blobs extracted from the stock android. I tried to put them to different locations, like /lib/firmware/ , /lib/firmware/rtlwifi/ and so on but that didn't help
Does anyone running the chip with success? Any thoughts on what I am missing?
Thanks in advance

maybe the reason is some compiler only see /hal/rtl8822b/hal8822b_fw.h but didn't see hal/rtl8822b/hal8822b_fw.c

so , the code like this in hal8822b_fw.h will become empty, that's why firmware load failed

extern u8 array_mp_8822b_fw_ap[106848];
extern u32 array_length_mp_8822b_fw_ap;
extern u8 array_mp_8822b_fw_nic[161240];
extern u32 array_length_mp_8822b_fw_nic;
extern u8 array_mp_8822b_fw_wowlan[103328];
extern u32 array_length_mp_8822b_fw_wowlan;

 

to slove this ,  just copy hex fiirmware part from hal8822b_fw.c to  hal8822b_fw.h, detail in this commit.

https://github.com/ChalesYu/rtl8822bs-aml/commit/27fef585225a52913b2936f91abf36859ec20a43

I have the same tv box and I tried this solution but it did not work.  The module compiles but when I load it I get the same error.  I looked into the code and it seems like the FW is accessible but not loading in memory.

 

Any other solutions I can try?

 

Thanks!!
