# General

The first rootfs image from Yocto, is not the final image.

You can use final_rootfs (already deployed to Laptops where the image is flashed to devices)

On Alex Windows PC is located at (D:\ROCKCHIP - FlashTool\RKDevTool\RKDevTool\rockdev\ImageSTB\rootfs.img)

OR if someone wants to start from clean rootfs image, must follow this guide.

And then create the final image, by running on device:

```

umount /dev/mmcblk0p3

dd if=/dev/mmcblk0p3 of=/data/new_rootfs.img bs=1M

```

Then copy this image to PC using WinSCP software

## Clean setup - prepare rootfs

1. copy rtl_bt as described in bluetooth notes

2. change /etc/fstab to auto load /data (Flash device notes)

3. link /data/settings/10-eth0.network to /etc/systemd/network (+ chage mode to 666)

4. disable and mask rngd and rng-tools services

5. execute:

systemctl disable dnsmasq

(this service is only used when WiFi is access point, it is enebled from init_py script)

6. mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig

7. change /etc/apache2/httpd.conf

<IfModule dir_module>

    DirectoryIndex index.html index.php

</IfModule>

8. write permissions to httpd.conf:

chmod 666 /etc/apache2/httpd.conf

9. allow php to do system restart:

chmod u+s /sbin/reboot

10. allow php to execute dd command:

chmod u+s /bin/dd

11. chmod u+s /usr/bin/timedatectl

12. copy /home/root/extra.qmap from PC to device

13. pip3 install python-uinput

pip3 install evdev

pip3 install wget

pip3 install tqdm

pip3 install gpiod==1.5.4

14. change /etc/pulse/client.conf

autospawn = yes

allow-autospawn-for-root = yes

15. for USB disk

mkdir /media/disk

mount /dev/sda1 /media/disk

16. vi /etc/hostname

change to "FBX-3566"

17. create startup systemctl services as described at System setup notes

18. create links

ln -s /data/firmware/htdocs /usr/share/apache2/default-site/htdocs

ln -s /data/firmware/eglfs.conf /home/root/eglfs.conf

ln -s /data/settings/10-eth0.network /etc/systemd/network/10-eth0.network

## Useful commands

In case ethernet module has output clock 125Mhz:

phytool write eth0/0/0x1e 0xa012

phytool write eth0/0/0x1f 0x0070

phytool write eth0/0/0x00 0x9140

to read MAC address directly from EMMC:

dd if=/dev/mmcblk0 skip=7170 of=tmp.img bs=512 count=1

then open this file, first 6 bytes is MAC address

copy /home/root/extra.qmap from PC to device
