w8997 FW CRC error

[chengeneg]

When the W8997 driver module with kernel version 4.4.50 is installed on the arm platform, the driver cannot be loaded properly and a FW CRC error indicated by the helper is displayed. len = 0x0011, txlen = 17 Abnormal print, suspect whether the firmware is incorrect

, download the firmware for git clone https://github.com/NXP/imx-firmware.git command of NXP, NXP_FIRMWARE \ took imx - the firmware, NXP, FwImage_8997 directory firmware, don't know whether it is right, If no, provide the firmware download path

[chengeneg]

I do not know whether the driver of this version supports the PCIE W8997 NIC driver mwifiex-lf-6.1.36_2.1.0, or whether the W8997 NIC driver has other versions. If yes, please inform me where to download the driver

Hi, @chengeneg 

What is your meaning of NIC?

If you are using this driver: mwifiex-lf-6.1.36_2.1.0, it means you downloaded from our git hub:

https://github.com/nxp-imx/mwifiex/tree/lf-6.1.36_2.1.0

Am I right?

This driver version is supported on Linux kernel  4.4.50, and also support PCIE-UART interface for Wi-Fi and Bluetooth.

And about the FW, yes, you are right. You can download firmware from this git hub:

https://github.com/NXP/imx-firmware.git

We suggest you choose same version with driver.

Can you please let me know your host side platform? Are you using our I.MX series board?

Best regards,

Christine.

Hi, @chengeneg 

Are you using arm 32 bit or arm 64 bit host plat form?

Did you put the firmware in /lib/firmware/nxp/ directory on your board?

And can you please provide me your loading Wi-Fi driver parameter and full dmesg logs for further checking?

Best regards,

Christine.

1.平台使用高通平台的QSDK，32位的arm，内核版本为linux-4.4.50
2.驱动版本为网站下载的mwifiex-lf-6.1.36_2.1.0，固件也为该版本mwifiex-lf-6.1.36_2.1.0.firmware
3.驱动加载为insmod mlan.ko , insmod mlan.ko mod_para=nxp/wifi_mod_para.con drvdbg=0xa0037

需要知道根据日志显示是否为估计不匹配问题，如果为估计不匹配请提供固件下载路径，一下为日志消息

Hi, @chengeneg 

请用附件给出的firmware 文件，放在您板子的如下路径： /lib/firmware/nxp/

并同步检测一下 该路径下的wifi_mod_para.conf文件中，PCIE8997部分是否与如下内容一致？

PCIE8997 = {
cfg80211_wext=0xf
max_vir_bss=1
cal_data_cfg=none
ps_mode=1
auto_ds=1
host_mlme=1
fw_name=nxp/pcieuart8997_combo_v4.bin
}

加载Wi-Fi driver 参数：

insmod mlan.ko

insmod moal.ko mod_para=nxp/wifi_mod_para.con drvdbg=0xa0037

Best regards，

Christine.
