BMI errors while loading driver module

Hi all,

I am trying to get an SDIO WIFI module, which has a QCA9377-3, working on my system.

The host system is based on Nvidia AGX Xavier. And the kernel is 5.10.

There are some failures during the driver initialization, such as

"[ 36.338188] +HTCWaitCtrlMessageRecv

[ 41.626161] HTCWaitTarget - Exit (-1)

[ 41.626199] -HWT

[ 41.626274] R0: [insmod][13:03:47.819798] wlan: [7888:F :VOS] vos_open: Failed to complete BMI phase

What does this failure mean?

From the driver source code (CORE/VOSS/src/vos_api.c),

function "HTCWaitTarget" is called after bmi_download_firmware(),

can we assume that the driver FW has been downloaded successfully?

If so, what prevents the BMI phase to be completed?

Is this failure related to the SDIO communication?

Following are parts of dmesg logs while loading the driver module:

Hi Jiangjie,

There is a timeout happening in HTCWaitRecvCtrlMessage function.

adf_os_re_init_completion(target->CtrlResponseValid);

/* Wait for BMI request/response transaction to complete */

if(!adf_os_wait_for_completion_timeout(&target->CtrlResponseValid,

adf_os_msecs_to_ticks(HTC_CONTROL_RX_TIMEOUT))) {

if(hif_set_target_reset(target->hif_dev))

VOS_BUG(0);

return A_ERROR;

}

It could be an SDIO bus related issue that caused BMI timeout. The BMI phase is the initial communication between the driver and the WLAN Hardware. Please check SDIO is working OK or not.

Thanks.

Hi ddeepakk,

Thanks for your reply.

Now we managed to load the driver successfully with 1-bit SDIO mode,
but the 4-bit SDIO mode still fails with the aforementioned errors.

Any idea?

Thanks.
