SD8978 firmware load fail

vmbtech — Tue, 25 Jun 2024 06:53:38 GMT

Hi all,

The driver and fw version is lf-5.15.71_2.2.0

After firmware load the driver reports with

[ 94.244794] Fail to poll firmware status: firmwarestat=0x5f5f

I did some modification to the driver and found that the firmwarestat initially comes back 0xf00a before settling on 0x5f5f

I'd like to know exactly what this means so I can diagnose why my driver is failing to get past the firmware load.

What I need is register definitions for the status_reg_0 and status_reg_1, or at least the meaning of 5f5f and f00a

Hi,

Could you please help me with the following information?

- What host are you using?

- Are you using a module?

- Please share with me the FW (i.e. 17.92.1.p149.131) and Driver (i.e. MM6X17437.p3-GPL) version

- Please share with me the whole terminal output of your test

Regards,

Daniel.

host is an stm32mp133 soc

yes the module is a u-blox maya-w166

firmware and driver version are both lf-5.15.71_2.2.0

I have tried lf-6.6.23_2.0.0 but no difference

Full output is

Thanks for the information.

I just did a test on my side using 1XK module with an iMX8MP EVK and it is working on my side in Linux 5.15.71.

Are you using a custom board for the Host? Have you double checked if a HW rework is needed on your board?

Regards,

Daniel.

Re: SD8978 firmware load fail

vmbtech — Fri, 28 Jun 2024 12:34:47 GMT

Yes this is a custom board, and it may be true that some power up conditions are not 100% true to the datasheet.

But...

It would be really helpful to get the meanings of those firmwarestat values though, if at all possible.

"firmwarestat=0x5f5f" and f00a

After all, they must have a specific meaning within the module/chipset itself

Re: SD8978 firmware load fail

DanielRuvalcaba — Fri, 28 Jun 2024 19:44:07 GMT

Could you please take a look this thread? Seems like a similar issue.
Please share with me your wifi_mod_para.conf

Regards,

Daniel.

Re: SD8978 firmware load fail

vmbtech — Mon, 01 Jul 2024 16:32:21 GMT

This is the config file

I know it works because the firmware load works on some prototype boards but fail on some others

SDIW416 = {
       cfg80211_wext=0xf
       max_vir_bss=1
       cal_data_cfg=none
       ps_mode=1
       auto_ds=1
       host_mlme=1
       fw_name=nxp/sdiouartiw416_combo_v0.bin
}

Would still love to know what those firmwarestat values mean

Re: SD8978 firmware load fail

DanielRuvalcaba — Mon, 01 Jul 2024 18:20:28 GMT

I will need to check this internally.

Give me some time to get an update.

Daniel.

Re: SD8978 firmware load fail

DanielRuvalcaba — Wed, 03 Jul 2024 21:15:55 GMT

Hi @vmbtech,

Please confirm the following.

1. The log you attached is with 5.15.71 driver (SDIW416---16.92.21.p55.3-MM5X16366.p5-GPL-(FP92)) in Linux 5.15.71.

2. If you do not modify the driver, you only get 0x5f5f. But if you modify the driver, you get the same 0x5f5f value, but you notice that 0xf00a appears first, am I right?

Regards,
Daniel.

Re: SD8978 firmware load fail

vmbtech — Thu, 04 Jul 2024 10:03:54 GMT

Yes that is all correct, 5.15.71, and the modification to the driver was to print out the value of the register for all the retries before retry limit is reached, which shows the register changing

Hi Team,

I am also facing same challenge in my board. I am waiting for response Daniel.Could you please provide any quick response on this problem. Is this firmware loading timing issue?

Hi,

The values 0x5f5f and 0xf00a indicates the FW is stuck during Init time. More details about these values are for internal use only, this is why we don't have any user manual or guide available.

Regards,

Daniel.
