Chip BCM4345/6 firmware error -2 in a raspi pi3 B+

I copied from this git https://github.com/yangxuan8282/phicomm-n1/wiki/Drivers files:

brcmfmac43455-sdio.bin
brcmfmac43455-sdio.txt

To directory /lib/firmware/brcm

I restart openwrt and I give error again, but this time is different from the initial

Now he's asking me for another firmware file:

brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt

I looked it up in the github, but I can't find it.

Someone has experience with openwrt on a raspberry pi 3 B+ ???????

Since I'm getting out of this mess, I'm out of ideas.

Maybe the files to use are other, I don't know.

dmesg tells me this:
