Hi @zakariya ,

I see that "registered new interface driver brcmfmac". Do you see the wlan0 interface?

Can you show me the contents of /lib/firmware/cypress? I need this to make sure you have the clm, firmware and the nvram files with the right file names.

Thanks

Hello @raks_99,

I don't see the wlan0 interface.

refer below for contents of the files under /lib/firmware/cypress;

--------------------------------------------------------------------------------------------------

root@am335x-evm:/lib/firmware/cypress# ls -l
-rw-r--r-- 1 root root 419798 Dec 16 2021 cyfmac43364-sdio.bin
-rw-r--r-- 1 root root 4733 Dec 16 2021 cyfmac43364-sdio.clm_blob
-rw-r--r-- 1 root root 701 Dec 16 2021 cyfmac43364-sdio.txt
root@am335x-evm:/lib/firmware/cypress#

--------------------------------------------------------------------------------------------------

appreciated the quick help and workaround.

Thanks,

Mohammed

Hi @zakariya ,

Can you replace 43364 with 43430 in the file names (for example cyfmac43430-sdio.bin) for all three files? There is no definition for cyfmac43364-sdio in the file sdio.c, this is probably why the driver is unable to find the files.

Thanks

Hello @raks_99 ,

more input from us for your reference;
SD card is getting detected but sdio logs not seen on dmesg, also this Murata
EVk board is connected to AM335x via wires externally.

Thanks.

Hello @raks_99 ,

I am still having challenge to go through it. somehow one step forward but not solved yet.

please see below details for reference;

1. once mmc detected, we inserted the driver and observe the wlan0 via ifconfig

2. once tried to run wpa_supplicant or dhcp to get ip, it throws an error. 

3. please find attached logs for the sequence performed.

 

keep advising, 

thanks.

Hi @zakariya ,

1. Are you using the cyfmac43430* file name right now for the firmware, nvram.txt, and clm blob? 

2. Can you try scanning via the wl tool?

- Start udhcpc

- Run "wl scan"

-Run "wl join ap_ssid"

ap_ssid should be an open network. Can you try this and check if the device is able to connect?
