Hi, I’m trying to bring up “BeagleMod CC33” Wi-Fi module on a BeagleY-AI board running “6.12.24-ti-arm64-r42” kernel. Buuut currently, no luck at all, and I’m sort of out of ideas, so any help would be appreciated.
What I’ve currently tried:
Updated dts (attached, based on BeagleBoard-DeviceTrees/v6.12.x-Beagle )k3-am67a-beagley-ai.dts (31.1 KB)
lssdio script reports
Host 2 Address 0001 Function 1: ID 0097:4077 (Class 02)
Host 2 Address 0001 Function 2: ID 0097:4077
lspci shows

The overall feeling is that it is the kernel ignoring the module, or I’m missing something very important in the dts.

Can you verify that you have these modules?

I see that there was only CC33XX_SDIO in your logs.
Sure, here:

My configuration slightly differs from yours. Do I need an CC33XX_SPI driver (in case SDIO is used)? And whole BT_TI thing if I don’t need a Bluetooth. Thanks for helping btw.

You are right. If your setup doesn’t have BLE, you don’t need CONFIG_CC33XX_SPI and BT things.
I haven’t know-how about this issue either. I’ve only recently bring up the chip with 6.1.
The only thing I am sure of is that there is no problem on the hardware side since the device appears in the MMC bus succesfully.
I hope, someone will help you to solve your problem.

Can you share your full defconfig?
Regards,
With pleasure!
