I'm trying to test the cyfmac54591 module with an NVIDIA Jetson Nano, and running into an issue with loading FW during 'insmod brcmfmac.ko' :

from dmesg:

[  785.339047] brcmfmac 0000:01:00.0: loading /lib/firmware/cypress/cyfmac54591-pcie.nvidia,jetson-nano.txt failed with error -22

I've compiled the kernel modules (compat, cfg80211, brcmutil, brcmfmac) on the Jetson Nano using sources from cypress-backports-v5.4.18-2020_0925-module-src.tar.gz, and copied the contents of cypress-firmware-v5.4.18-2020_0925.tar.gz to a new folder /lib/firmware/cypress.  I modified the kernel config file as described in the README in order to prevent error during 'insmod compat.ko'  

I don't see any .txt files in my /lib/firmware/cypress folder, is there a way to specify which FW file to use, or am i supposed to generate the .txt file somehow?

The cyfmac54591-pcie.txt NVRAM file should be present in the /lib/firmware/cypress directory. If it is not available, kindly contact your module vendor to obtain the nvram file. There is no need to specify the FW, the driver will automatically enumerate the connected WLAN chip over PCIE interface and select the cyfmac54591-pcie.bin and clm_blob file for loading. But the /lib/firmware/cypress should contain the three files in the naming convention shown below:

cyfmac54591-pcie.bin

cyfmac54591-pcie.clm_blob

cyfmac54591-pcie.txt
