6 Bring-up of Wi-Fi interfaces
This section describes the bring-up steps for the Wi-Fi interfaces on the i.MX 8M Quad.
6.1 Load the modules
Follow these instructions to load the driver modules and bring up the 88W8987-based
module.
• Update and verify the module parameters in the file wifi_mod_para_sd8987.conf
root@imx8mqevk:~# vi /lib/firmware/nxp/wifi_mod_para_sd8987.conf
SD8987 = {
cfg80211_wext=0xf
wfd_name=p2p
cal_data_cfg=none
max_vir_bss=1
fw_name=nxp/sdiouart8987_combo_v0.bin
}
• Use the following command to load the modules in kernel
root@imx8mqevk:~# modprobe moal mod_para=nxp/wifi_mod_para_sd8987.conf
• Verify the kernel debug messages
