How to use an external WiFi card on 8MMINILPD4-EVKB?

[jun_1]

Could you please tell me the procedure to use external WiFi card through M.2 connector of 8MMINILPD4-EVKB? I am trying to use Embedded Artist's 2DL M.2 Module with IW611 as the external WiFi card. 

I tried the following method, but the WiFi card was not recognized.

<Procedure>

1) Download the following 4 files from the following site and copy them to /lib/firmware/nxp.

https://github.com/nxp-imx/imx-firmware/tree/lf-6.1.22_2.0.0/nxp

My EVK runs Linux kernel Version: 6.1.22, so I chose the above branch.

sd_w61x_v1.bin.se
sduart_nw61x_v1.bin.se
uartspi_n61x_v1.bin.se
(The above 3 files are under FwImage_IW612_SD.)

wifi_mod_para.conf

I referred to the following link for the method.

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Steps-to-replace-the-NXP-Wi-Fi-Bluetooth... 1276955

2) Execute the following command

wpa_passphrase <SSID> <PASS> >> /etc/wpa_supplicant.conf
modprobe moal mod_para=nxp/wifi_mod_para.conf
wpa_supplicant -B -i mlan0 -c /etc/wpa_supplicant.conf -D nl80211
udhcpc -i mlan0

For the below question, I just found that there is not  "imx8mq-evk-usdhc2-m2.dtb" inside LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip, even if it is the latest release. Could you please tell me Which release includes "imx8mq-evk-usdhc2-m2.dtb", or Could you send me that .dtb file?

Hello @jun_1 

imx8mq-evk-usdhc2-m2.dtb this dtb file is for i.MX8MQ, not for i.MX8Mmini.

For i.MX8mm evk, M.2-SD is not supported in hardware. We only leave test point, you need to connect test point to SD2 which is micro sd slot then change dts to configure SD2 to m.2 SD.

The M.2 is default for pice card.

For the below inquiry, it seems that M.2 connector activation is required, however on the procedure, I have another issue.

I am trying to enable SDIO on M,2 connector refering to Page 49 of UM11483.After I excute the following command, I cannot exit from u-boot even if I hit any key within 2 sec time limit.

u-boot=> setenv fdtfile imx8mq-evk-usdhc2-m2.dtb
u-boot=> saveenv
u-boot=> reset

There is an error which says "Failed to load 'imx8mq-evk-usdhc2-m2.dtb" on the console. I think this causes the above issue.　Is there any solution for this? When I don't excute the following command, I can quit u-boot and back into the normal boot.

I tried the following procedure based on UM11483 page 70, after installing  LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip, but console log says wlan: version = SD8987, not SDIW612. Is there additional work before  executing "modprobe moal mod_para=nxp/wifi_mod_para.conf"?

Procedure:

1) I edit /lib/firmware/nxp/wifi_mod_para.conf as follows.

SDIW612 = {
cfg80211_wext=0xf
wfd_name=p2p
max_vir_bss=1
cal_data_cfg=none
drv_mode=7
fw_name=nxp/sduart_nw61x_v1.bin.se
}

2) I executed the following command.

modprobe moal mod_para=nxp/wifi_mod_para.conf

The above problem has been resolved. The following command worked.

.\uuu LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip\uuu.auto-imx8mmevk

[jun_1]

Thank you for your answer. I am trying to rewrite the OS after reading the linked documentation, but when I try to rewrite the OS using with uuu, I get an error. I have tried on both Windows and Ubuntu PCs. Could you please advise me on this error?

On Windows, I put the following files in the same directory. In this directory, I started PowerShell and ran ".\uuu.exe LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip", but I get an error. USB connectors: J901,J301,J302 are connected to a Host PC(J901 is not connected when using Linux Host PC), and dip switches on EVK are set to Serial download mode.

uuu.exe
uuu
uuu.auto, which is placed inside LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip
libusb-1.0.dll
LF_v6.6.3-1.0.0_images_IMX8MMEVK.zip

Here is the log:
