NXP IW612 Kernel Integration & Firmware Flashing Issues

[JayKumar]

Description: We are integrating the Murata LBES5PL2EL module (based on NXP IW612) with the Telechips platform and facing the following issues:

1. Kernel Integration Challenges:

   • NXP Kernel Version: 7 vs. Telechips Kernel Version: 5.4 causing incompatibility.

   • Compilation failures due to missing/modified kernel functions.

   • Need guidance on backporting NXP drivers to kernel 5.4.

2. Firmware Flashing Issues:

   • Timeout error: "Timeout for waiting header signature in fw_Change_Timeout function."

   • Download failure: "Download Error - Error code is -1."

   • Need assistance in debugging flashing failures.

3.  Support Required:

   • Clarifications on power management signals (WL_EN, BT_EN, PMU_EN) and reset handling.

   • Best host interface selection (SDIO, UART, PCIe) and firmware loading process.

   • Confirmation on Bluetooth & Wi-Fi stack integration requirements.

Requesting NXP's support and guidance on resolving these integration and flashing issues. Any insights or recommended solutions would be highly appreciated.

Thank you.

Dear @JayKumar ,

Could you give me the following information on your side?

1.  Is the Telechips platform ARM64 ARCH?

2. ARM gcc version

3. IW612 driver version

--When did you get it? from github or NXP website?

--Tell me driver & firmware version, please!

4. Do you have the source code of Telechips platform bsp including linux kernel?

Thanks!

Regards,

Dear @JayKumar 

Thanks for your detailed information!

Would you like to follow these steps to load WiFi driver?

(1) Getting the latest driver from github.

--driver
#git clone https://github.com/nxp-imx/mwifiex.git
#cd mwifiex

# git tag

# git checkout lf-6.6.52_2.2.0

(2) Getting firmware & wifi_mod_para.conf

--firmware 

https://github.com/nxp-imx/imx-firmware/tree/lf-6.6.52_2.2.0/nxp/FwImage_IW612_SD

[Note]

--If you want to use WiFi & Bluetooth, Select "sduart_nw61x_v1.bin.se", please!

--If you want to use WiFi, Bluetooth & 802.15.4, Select "sd_w61x_v1.bin.se & uartspi_n61x_v1.bin.se" , please!

--wifi_mod_para.conf

https://github.com/nxp-imx/imx-firmware/tree/lf-6.6.52_2.2.0/nxp

Download it, please! in the file, there exist SDIW612 node, like below, pay attention to fw_name, firmware file's name is fixed here. if you want to use other firmware , here should be changed.

for example, if you want single wifi, and hope to change firmware, sduart_nw61x_v1.bin.se should be changed to "sd_w61x_v1.bin.se ".

SDIW612 = {
cfg80211_wext=0xf
max_vir_bss=1
cal_data_cfg=none
ps_mode=1
auto_ds=1
host_mlme=1
fw_name=nxp/sduart_nw61x_v1.bin.se
}

For uartspi_n61x_v1.bin.se, if users want to use 802.15.4 feature, the firmware should be used, but it can' t be loaded via wifi_mod_para.conf, NXP has a tool named fw_loader, it can download the firmware over UART interface to IW612 module.

(3) Copying firmware & wifi_mod_para.conf to /lib/firmware/nxp on your linux platform of board.

if there is nxp folder on your board, create it, please!  then copy firmware & wifi_mod_para.conf to the folder.

(4) Building WiFi driver

-- Building linux kernel source code of Telechips platform.

-- Building WiFi driver

# export KERNELDIR= .../your built kernel source code above

Then set your cross compile environment, which is determined by your linux bsp.

[Note]

Please check if wlan_src/Makefile of wifi driver needs to be changed according to your cross compile environment!

After building wifi driver is done, you will get 2 .ko files:

mlan.ko & moal.ko

copy them to a folder of your boards,  for example /home/xxxx/iw612

(5) Loading wifi driver

# cd ~/iw612

# insmod mlan.ko

# insmod moal.ko mod_para=nxp/wifi_mod_para.conf

Then you will know if the driver can be loaded successfully.

if errors occurs , please get linux logs using dmesg, and share it with me!

Thanks!
