after install ath10k_pci module on ls1021a TWR Eva wlp1s0 scan fail

[jiye]

I followed the LSDK 1906 and compile the kernel and installed the modules 

I also install the firmware under /lib/firmware/ath10k

root@localhost:/lib/firmware/ath10k/QCA6174/hw3.0# ls
board-2.bin board.bin firmware-4.bin

lspci:

00:00.0 PCI bridge: Freescale Semiconductor Inc Device 0e0a (rev 20)
01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

iwconfig:

can1 no wireless extensions.

sit0 no wireless extensions.

eth1 no wireless extensions.

wlp1s0 no wireless extensions.

eth0 no wireless extensions.

can0 no wireless extensions.

eth2 no wireless extensions.

lo no wireless extensions.

I can't scan from the interface wlp1s0:

it says :

wlp1s0 Interface doesn't support scanning.

then i did a ifconfig:

wlp1s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether e8:2a:44:84:cb:9f txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

why it says ethernet.

Suppose to be wireless 

[jiye]

I finally made it work I need to some more experiments to make sure what is the cause? It's more likely the wpa_supplicant service. I used network-manager to make it work :smileyhappy:.

Finally!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Thanks for all the efforts you have put.

[jiye]

After I did what you tell me to do still the same result

when I used network manager it shows :

"Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter"
wifi (ath10k_pci), E8:2A:44:84:CB:9F, hw, mtu 1500

I can see the mac address of my wifi chip does this mean it has connection issue because of the linux distribution ?

[yipingwang]

After booting up the target board, please run "lspci -v" to check whether this PCIe device can be detected.

Would you please provide the console log to me when run "lspci -v"?

Hello Elias Bitbaker,

In LSDK 19.06 PCIe feature was disabled, please add the following configuration in Linux Kernel configuration file.

Please run "make ARCH=arm menuconfig" in flexbuild_lsdk1906/build/linux/linux/arm32/LS/output/LSDK-19.06-V4.19.

-> Bus support

   -> PCI controller drivers

       -> DesignWare PCI Core Support

            [*]Freescale Layerscape PCIe controller   

Please modify dts file in arch/arm/boot/dts/ls1021a.dtsi  as the following, Kernel source is in packages/linux/linux.

After rebuild Linux Kernel and boot up the target board, please run "lspci -v" to check whether the PCIe device can be detected.

Also I did not see .dtsi file I only saw .dtb I convert into .dts to do the modification 

[jiye]

this is my original one:

pcie@3400000 {

reg = <0x0 0x3400000 0x0 0x10000 0x40 0x0 0x0 0x2000>;

};

yours is 

interrupts = <GIC_SPI 181 IRQ_TYPE_LEVEL_HIGH>,
                                           <GIC_SPI 183 IRQ_TYPE_LEVEL_HIGH>; /* aer interrupt */

   interrupt-map = <0000 0 0 1 &gic GIC_SPI 91  IRQ_TYPE_LEVEL_HIGH>,
                                        <0000 0 0 2 &gic GIC_SPI 188 IRQ_TYPE_LEVEL_HIGH>,
                                        <0000 0 0 3 &gic GIC_SPI 190 IRQ_TYPE_LEVEL_HIGH>,
                                        <0000 0 0 4 &gic GIC_SPI 192 IRQ_TYPE_LEVEL_HIGH>;
                };

are these name conventions are still valid? 

[jiye]

it shows me syntax error in this line 

interrupts = <GIC_SPI 181 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 183 IRQ_TYPE_LEVEL_HIGH>; /* aer interrupt */

would you be able to verify?

[jiye]

I achieved to the step 4 and use ifconfig to see the interface wlp1s0

But it shows me does not support scanning. Plug or unplug the wifi module

wont make any difference for the lspci

Without the SX-PCEAC2 attached on the board it shows the same result:

root@localhost:/lib/firmware/ath10k/QCA6174/hw3.0# lspci

00:00.0 PCI bridge: Freescale Semiconductor Inc Device 0e0a (rev 20)

01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless

Network Adapter (rev ff)

So without or with the SX-PCEAC2 it shows the same result.

It seems like the device 1021a TWR can not recognise the wifi module.

Then I read

http://cache.freescale.com/files/32bit/doc/ref_manual/TWR-LS1021ARM.pdf

section 2.8

Do you think is because the board is not configured correctly
