88W8801(LILY W131) WiFI SDIO chip - not responding after FW download

[luqtd]

Hello, I am trying to run the 88W8801 on an Nvidia AGX Orin, but unfortunately, I'm experiencing issues with a lack of response after fw_download. Any idea why this might be happening?

When i remove the module with "modprobe -r moal" and probe it again. I am getting also logs like this.

Hi,

I just did a test using an iMX8MP running Linux 5.15.71 and a 2DS wireless module and seems to be working on my side.

If it’s not clock gating, do you have any idea why this might be happening?

[DanielRuvalcaba]

Hi,

I'm not entirely sure. 

Nevertheless, I notice the fw is not being downloaded to the SoC since you get a "WLAN FW already running! Skip FW download". Is there any step you execute before the logs you sent me?

Regards,

Daniel.

[luqtd · Accepted solution]

I'm not entirely sure why, but removing the no-sd property and changing the bus-width from 4 to 1 in the device tree seems to have resolved the issue. I’ll investigate this further and will post updates here on what I find.

Interestingly, after the first firmware download, it started working even with the original device tree configuration. Really strange behavior.

[luqtd]

I think the main difference is that I’m using Nvidia’s board with a relatively newer kernel.

I’ve noticed that my Nvidia’s board uses Clock Gating. Do you think that could be causing the issue?

[DanielRuvalcaba]

Hi,

What OS version are you using?

What Driver and FW are you using?

Could you please share with me the whole terminal output of your test (commands)?

Regards,

Daniel.

[luqtd]

I am using a Linux OS based on Nvidia-Jetpack(v36.3) with kernel 5.15.136-l4t. I also tried it on kernel 5.10, but the result was the same.

Driver: github.com/nxp-imx/mwifiex.git - branch: lf-5.15.71_2.2.0

Firmware: github.com/NXP/imx-firmware.git - branch: lf-5.15.71_2.2.0

The command i use:

modprobe moal

I also tried but the result was the same

modprobe moal mfg_mode=1 cal_data_cfg=none drv_mode=1 fw_name=nxp/sd8801.bin

Thanks in advance for help!
