I have a Murata 1DX PMOD module that I'm trying to use with my Zedboard and PetaLinux 2020.2. Configuring the Zynq and instantiating the actual PetaLinux project went fine without a hitch, but after I've compiled the image and booted it up, the wifi driver appears to have failed to load. The error message I get is the following:
Direct firmware load for brcm/brcmfmac43430-sdio.bin failed with error -2
Looking at the filesystem, I can see that there is no /lib/firmware directory at all, so it's not surprising the driver failed to load the bin file. Which leads me to my question, what is the recipe I need to actually get that firmware image built and into the rootfs? The Zedboard BSP Xilinx provides clearly doesn't include that support by default. My assumption here is that Avnet had to deal with something similar to this for the sake of the Minized, which includes the Murata chip as part of the PCB. And the ability to be able to generate a PetaLinux image from a custom project would be kind of important for the Minized, since being reliant solely on the reference images pretty much nerfs any ability to actually develop custom logic for use in the PL section of the Zynq.
