Write image on SD card

My SD card is on drive sdb

Change bootloader

cd /mnt/
mkdir sdp1
mkdir sdp2
mount /dev/sdb1 sdp1/
mount /dev/sdb2 sdp2/
cd sdp1/

On file config.txt change these lines

kernel=uboot.bin
device_tree_address=0x02000000

by these ones:

#kernel=uboot.bin
#device_tree_address=0x02000000
kernel=vmlinuz
initramfs initrd.img followkernel

Copy device-tree files

cp /mnt/sdp2/lib/firmware/4.15.0-1017-raspi2/device-tree/bcm2710-rpi-3-b-plus.dtb ./
cp -r /mnt/sdp2/lib/firmware/4.15.0-1017-raspi2/device-tree/overlays/ ./

We change files bootcode.bin, fixup.dat and start.elf

cd /tmp/
wget http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-bootloader_1.20180417-1_armhf.deb
dpkg-deb -x raspberrypi-bootloader_1.20180417-1_armhf.deb /tmp/pi-bootloader
cd /tmp/pi-bootloader/boot
cp * /mnt/sdp1/

We update Wifi drivers

cd /mnt/sdp2/lib/firmware/brcm
mv brcmfmac43340-sdio.bin brcmfmac43340-sdio.bin.bak
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.bin
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.clm_blob
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.txt

Unmount the SD card

cd /mnt/
umount sdp1
umount sdp2

The system boot, but kernel panic with network card,... kernel 4.15 does not work :(
