Orange Pi Zero - Stable - Realtek 818x wifi dongle issue

Just bumped this one:

 

Orange Pi Zero, stable version, legacy kernel

Trying to insert Realtek WiFi dongle (8188eu in my case).

Module cannot load - with this error:

Quote

ERR: script_get_item wifi_usbc_id failed

 

Peeked solution on 4pda - http://4pda.ru/forum/lofiversion/index.php?t750921-1740.html - decompiled script bin and set wifi_usbc_id = 1 - before it was set to none.

Original solution has value "2", but it was just a guess, so I used "1". Module worked in parallel with original xradio. According to original poster on 4pda, this issue was seen on Orange Pi PC.

 

Not sure, is it correct solution, but, well - it may help.

 

Issues seen - when I try to unload realtek module, then modprobe back with some other parameters for powersaving or mac changing wia rtw_xxx options - original xradio gets also resetted. 

 

Issue with wifi_usbc_id does not show up, if i use ralink 2800 dongle for example.

 

Hope it is not a duplicate topic and may help others somehow.

I tore out the crappy wifi on my OPi Zero just now and was trying to use an external realtek dongle. No luck until I copy-pasted the wifi section out of the fex from an OPi without wifi, e.g.


[wifi_para]
wifi_used = 0
wifi_sdc_id = 1
wifi_usbc_id = 5
wifi_usbc_type = 1
wl_reg_on = port:PL07<1><default><default><0>
wl_host_wake = port:PG10<0><default><default><0>
wl_host_wake_invert = 0
 

Replacing the wifi_para in orangepizero.bin with this disabled the onboard wifi and allowed my realtek to work. thx!
