mon0 interface not working RBI Zero 2W about nexmon HOT 1 CLOSED

Update on this:

I fixed it by using the patch for the bcm43430a1 chipset (7_45_41_46 version). Then, I had to copy the modified driver as stated in the Readme:

/home/pi/nexmon/patches/driver/brcmfmac_6.6.y-nexmon/brcmfmac.ko "<PATH TO THE DRIVER>/

And finally, change the binary of the 43436s chipset. I don't know why, as I've seen in the logs that the chip uses the 43430 binary, but it was not working until I executed the following:
sudo mv /home/pi/nexmon/patches/bcm43430a1/7_45_41_46/nexmon/brcmfmac43430-sdio.bin /usr/lib/firmware/brcm/brcmfmac43436s-sdio.bin

finally:

sudo depmod -a
sudo reboot

I used DrSchottky#8 for the fix.

As an additional comment, some of the instructions of the Readme are outdated. With this kernel, xxd package has to be manually installed and libisl.so.23.2.0 and libmpfr.so.6.2.0 are the current libraries to be used.
