[88W8997] MFG tool firmware loading fail when working on Nvidia NX platform

[varietytim]

Hi Sir,
our customer would like to integrate mfg tool to do whole system SRRC certifIcation, but we are facing a critical problem that the mfg's firmware bin file will load failed every time even we unload kernel inbox driver.
Could you please help us to figure out what may go wrong during mfg tool integration?

Dear @varietytim 

This issue has been fixed in latest Linux 6.1.22 release.

If you need to keep older 5.15.71 software, you can use the following workaround:

Replace

insmod moal.ko mfg_mode=1 drv_mode=1 cal_data_cfg=none fw_name=nxp/pcie8997_uart_combo.bin

With

insmod moal.ko mod_para=nxp/wifi_mod_para_mfg.conf

Having wifi_mod_para_mfg.conf content as below

PCIE8997 = {
    cal_data_cfg=none
    fw_name=nxp/pcie8997_uart_combo.bin
    drv_mode=1
    mfg_mode=1
}

 Regards,

Olivier

Hi,

Were you able to test this with another MFG release?

Regards,

Daniel.

[varietytim]

Hi Daniel,
any feedback about my previous reply? our customer is waiting for our further input.

thanks.

[DanielRuvalcaba]

Please accept my apologies for the late reply.

Could you please verify if this issue happens with this FW release only? Or is this still happens with any other release?

Could you please explain to me how you’re connecting the module to your host?

Regards,

Daniel.

[varietytim]

Hi Daniel,
the firmware loading fail was happened on MFG's specific firmware only.
you can compare what's difference on my previous reply.
Regarding of connecting module method, the host device is an edge micro server which has standard m.2 slot.
the mfg tool was executing on same system directly.

[DanielRuvalcaba]

Thank you for the feedback.

I’m going to try to replicate this.

Meanwhile, could you please try another MFG release and tell me if it works for you?

Regards,

Daniel.

[DanielRuvalcaba]

Hi,

Could you please tell me if you are using a module?

Regards,

Daniel.

[varietytim]

Hi Daniel,
Yes,the module's model name is AzureWave AW-CM276MA-PUR module.
