Hi,

I would like to use TL-WN823N V2 or rtl8192eu with openPLI 6.1 image, but I cannot find the proper driver. The device works well under ubuntu as described here https://askubuntu.co...nect-to-network. I found the source code of the driver here https://github.com/M...u-linux-driver, but I do not know how to create and ipk package.

Can you help me?

Thank you

[athoik]

Did you check feeds?

opkg update
opkg install rtl8192eu

opkg update

Thank you for your reply, it does not work:

opkg install rtl8192eu
Collected errors:
 * opkg_prepare_url_for_install: Couldn't find anything to satisfy 'rtl8192eu'.

Not every box has this driver, it depends on the kernel version and config.

I have openPLI 6.1 with linux kernel v.4.10.12 on h2h device. What can I do?

Thank you

[WanWizard]

Nothing much. It needs to be added to the kernel config if it's a kernel driver. And if not, a third party driver needs to be activated in the build. But that is beyond my expertise. 

[athoik]

But it is ...?

meta-openpli/recipes-openpli/images/openpli-enigma2-image.bb:	rtl8192eu \

[WanWizard]

The recipe is there, but it is not being build, there is no dependency that triggers it as far as I can see.

 

I'm 600km from my buildserver for a few weeks more, so I can't check myself.

[athoik]

EXTERNAL_WIFI_DRIVERS = " \
        firmware-rtl8192cu \
        \
        rtl8192cu \
        rtl8188eu \
        rtl8192eu \
        "

It seems that externalwifi triggers it.
 

        ${@bb.utils.contains("MACHINE_FEATURES", "externalwifi", "${EXTERNAL_WIFI_DRIVERS}", "", d)} \

We can try "IMAGE_INSTALL_append = " rtl8192eu" (in develop) and see if that will fail.

Edit1. Currently it builds for those models:

I know.

 

What I don't know is why it builds for those boxes, but not for others? BSP configuration? Kernel config?

[athoik]

It tries to locate the MACHINE_FEATURES externalwifi.

Most boxes seem to miss that feature.

So adding rtl8192eu to feed without checking machine feature seems possible solution.

Adding externalwifi to all BSP might take ages.

[WanWizard]

Probably. Maybe check with Erik before making changes,

[andrearossidec1]

Thank you for your effort. Let me know if I have or I can do something.

[Erik Slagter]

Why is this is an MACHINE_FEATURE to start with? It suggests that the low-level kernel driver is in the kernel, but only for some models (depending on kernel version and config). But according to Wanwizard the rtl8192eu driver is never in the kernel (which is really bad from Realtek).

..

static int rtl8192eu_load_firmware(struct rtl8xxxu_priv *priv)
{
    char *fw_name;
    int ret;

    fw_name = "rtlwifi/rtl8192eu_nic.bin";

    ret = rtl8xxxu_load_firmware(priv, fw_name);

    return ret;
}

..

This suggests rtl8192eu support in the (recent) kernel.

[WanWizard]

I checked 4.10.x and couldn't find it.

 

I know the externalwifi is there from DMM days, where the 2.6 kernel had virtually no support. 

 

I didn't spend much time on it, due to lack of it.

[Erik Slagter]

I checked 4.10.x and couldn't find it.

Maybe the issue is exactly that the support has been removed recently? I searched inside the 4.9 kernel source tree.
