Porting Yocto Rocko on pico-imx6ul - Bluetooth\Wifi doesn't work
Hi,
i'm porting the krogoth bsp to rocko for pico-imx6ul,
At the moment the board boots and seems ok, ethernet is working, usb and so on.
At the moment i'm strugglig to make wifi works.
I have installed Technexion files in /lib/firmware/brcm , i have the bcmdhd module correcly loaded, but i looks like that the the modules wan't boot
My result:
root@pico-imx6ul-emmc:~# modprobe bcmdhd
dhd_module_init in
Technexion official image output (for reference):

QCA9377 and Connman
Hi Technexion :),
I'm working on the TC-0710 with the new QCA wifi card. I'm using the reference image "core-image-salto" with one change : i had connman-client in order to have connmanctl.
On the example below i'm trying to connect to an open wi-fi network called PLOPINOU. The TC-0710 is the only device on this access point. And this access point work with other device like phone or TEP-1560-IMX6.

When I'm trying to connect to this access point connman return this error :
Error /net/connman/service/wifi_021f7bb50080_****_managed_none: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Furthermore every network is listed twice.
Finally i can't connect to my access point. But it's working well with iw on the same hardware (no twice wifi network and connection ok) and the same connman is working well too on a TEP-1560-IMX6.
Do you with any idea about the problem ? Can you reproduce this issue on your own hardware ?
Thank you,

Should be no more than 60Hz, or it's burning power for no good reason...
Wandboard Dual Rev. D1 WiFi && BT not working
Hey there! Happy new year everyone :)
This issue is very related to this one but since it's closed and I would still like to ask a question I'll open a new one.
Which combination of Linux kernel:
- Branch
- Defconfig
- (Possibly ARM gcc version)
shall I use to build the linux-technexion kernel?
I have a Wandboard Dual Revision D1 (with the new pmic) and I'm trying to build this very kernel on the branch "tn-imx_4.1.15_2.0.0_ga_ampak_bcmdhd_test" using the in-tree "wandboard_defconfig" configuration file, but compilation fails.
Iอ'm using a Yocto-generated toolchain with arm-poky-linux-gnueabi-gcc version 8.2.0, which I suspect is a bit too high for this kernel?
Since I bought my Wandboard more than one year ago I've misserably failed to make the Wifi/BT driver work, so when I found this branch ("tn-imx_4.1.15_2.0.0_ga_ampak_bcmdhd_test") I suddenly felt the urge of trying it out to see if works.
Big thanks in advance!
Best regards,
/Santiago
