It’s possible to patch the out-of-tree Broadcom “dhd” driver into the kernel tree
do u have some link for this patch ?
If these are the changes that you made? https://github.com/chewitt/linux/commit/ef32f1fa81b7a20fabc4220d55ae1074b6c890b8 please add https://github.com/chewitt/linux/commit/afdc9eff6f0e9bb7a7cfdadd201f5b5facc88324 and insmode again. It won’t make the driver work, but that’s the additional output that I need to send back to the linux-wireless mailing list.
https://gitlab.com/baylibre/amlogic/atv/linux/commits/narmstrong/v5.1/aml/integ-5.1-bcmdhd has the dhd driver sources (last few commits). I’m not sure if that branch is Android or Linux oriented so you might need to massage the commits a little to make them fit 5.3.
tnx for links !

i do same before )))) and have same result ))))))

ok! just add one lost definition and bcmdhd builded ) TNX
master@peace:/tmp/linux-5.3-rc4/drivers/net/wireless/bcmdhd$ grep get_ds wl_iw.c
#define get_ds() (KERNEL_DS)
set_fs(get_ds());
and have have this result
I can’t really comment on dhd as I don’t use it (our distro refuses to add it). If you can help with running the test (with the extra commit to add debug info) and share the output that would be appreciated. It’s the first step towards getting one of the Broadcom maintainers to take an interest in getting BCM4359 supported upstream.
failed ;(
Hi
This bcmdhd.1.579.77.41.x wifi driver can’t help for AP6398S support for mainline?

@hyphop, @balbes150 Can test if this wifi driver works?
It was confirmed compiling fine on kernel 5.3.0-rc5.
Can you advice me on how to add this to the package? So I can try and compile the kernel along with this and give it a try.
yes its possible to build ! but still not work!)
i try to solve this problem but some need time !
Please share your experience and also logs if you can get it.
I will pass it on to Rockchip and Ampak, maybe they can help to solve the remaining problems.
Broadcom/Ampak already ignored requests from Google re. mainline support so I wouldn’t raise your hopes on getting a response 
Hi Khadas team,
I found these links whilst evaluating whether to purchase the VIM3, as working wifi is critical to my situation:
And
Is there anyway this can be tested to determine whether it is a viable workaround whilst mainline support is missing?
For testing devices that frequently don’t have working WiFi from the comfort of my sofa (without using a 15m Ethernet cable) I acquired a used Apple Airport Express from eBay ($15). it’s configured in bridge mode so that any device I plug in via Ethernet has reliable WiFi with no dependencies on drivers, kernel versions, etc. … just a suggestion.
Apple Airport Express - need power from adapter (or its same by usb cable connected to same device )? + and price about 50USD and up, i think any usb wifi dongle with true supported chip its easy and price only 5 USD
PS: i have use orange-pi devices its just 10USD for same bridge usage , but he provide usb-ethernet <=BRIDGE=> wifi , and use only one usb cable and same no need special drivers )
@chewitt I sense some irony 
:
.
It appears VIM3 is shipping without working WiFi on many Linux distributions, even though its datasheet advertises Wifi AC as a feature.
.
There is nothing wrong with wanting / needing it to work for a specific use case, is there?
.
If there is an issue with my suggestion to use a patch that appears to have worked in making wifi useable on another board using the same chip, please let me know. It it is not applicable, I’d be interested in understanding why
.
u can use on-board WIFI with legacy kernel from khadas amlogic, its work !
but mainline kernel still not have support for this wifi chip!

It uses mains power (240v) and the last one I bought (used) was $13 inc. postage. If you want to support cheap Realtek USB devices with shit out-of-tree drivers, be my guest. I don’t
may be its 15 )) but real price for new apple devices is about 100$-150$ USD i think is too much ))) be sure normal cheap wifi dongle works same fine)))
why ? u dont like realtek ? ))) for me its lil strange
linux-kernel have good support for many realtek wifi chip RTL8xxxx
i have some very nice devices and cheap same time, its work without problems ! whats problem ?
It seems to me that we are talking about mainline support of ampak AP6398, containing Broacdom bluetooth and wifi chips, not Realtek…

I also think the new price is expensive, which is why I buy them used on eBay for $13 instead of new for $100-150. Good luck supporting your users with cheap Realtek USB dongles. The mainline kernel has support for older b/g/n chipsets not the current shipping b/g/n/ac chips that most users want to use. The newer chipset drivers are not in-kernbel and are not maintained by Realtek using any public sources, and they break with every kernel bump. That’s my definition of a crap driver. Your definition and tolerance may be different to mine.
Anyway… please focus your time figuring out how to get mainline kernel support for the Ampak module that ships in all of your boards.

When can we expect a working driver for VIM3 wifi on Linux side?
I see CoreElec have working wifi with 4.9 - Just for info.
