need more detailed logs, while it’s clear what should work

I downloaded the firmware-brcm80211_20161130-3+rpt3_all.deb package and found that I was missing a blob file for the brcmfmac43455. I added what you said for the cmdline.txt file. Attached is the latest dmesg log.

dmesg.log (15.6 KB, 12 views)

you have not added a parameter verbosity=7

[ 0.000000] Kernel command line: 8250.nr_uarts=0 bcm2708_fb.fbwidth=646 bcm2708_fb.fbheight=406 bcm2708_fb.fbswap=1 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000 dwc_otg.lpm_enable=0 console=tty1 nofont root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro

I added "dwc_otg.lpm_enable=0 console=tty1 nofont root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro verbosity=7" to /boot/cmdline.txt like you said

stop, wrong parameter needed loglevel=7

Let me know what I should do.

echo 'dwc_otg.lpm_enable=0 console=tty1 nofont root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro loglevel=7' > /boot/cmdline.txt
reboot
attach dmesg.log

Ok added loglevel=7 and attached dmesg log

nothing has changed

echo 8 > /proc/sysrq-trigge
modprobe -r brcmfmac
modprobe brcmfmac
attach dmesg

Attached is new log. Just says it unregistered and re-registered the module but nothing.

should be something like

everything should be in /lib and nothing in /lib64?

ls -l /lib{,64}/* | grep :$ | cut -d ':' -f1
/lib/dhcpcd
/lib/firmware
/lib/modprobe.d
/lib/modules
/lib/systemd
/lib/udev
/lib64/e2fsprogs
/lib64/pkgconfig
/lib64/xfsprogs

in /lib64 -> glibc, etc
in /lib -> kernel modules and firmware

Is /dev/mmcblk0p1 supposed to be mounted to /boot?

It doesn't have to be mounted there, although that's where it should be mounted when you do updates.

The critical point is that the first partition on the SD card is where the firmware, device tree, and kernel (and initrd, where applicable) must be in order to boot from the SD card. And the format must be FAT32.
