| 1 | 1 | Alex Seferidis | # Update STB firmware |
|---|---|---|---|
| 2 | |||
| 3 | The device has 4 partitions |
||
| 4 | |||
| 5 | - /dev/mmcblk0p1 (Uboot) |
||
| 6 | - /dev/mmcblk0p2 (Kernel) |
||
| 7 | - /dev/mmcblk0p3 (Rootfs) |
||
| 8 | - /dev/mmcblk0p4 (Data partition /data) |
||
| 9 | |||
| 10 | On device: |
||
| 11 | |||
| 12 | |||
| 13 | On data partition there is a folder /data/firmware (web pages, DS application, IPTV application and executables lemcoplayer, externalplayer) |
||
| 14 | When we do firmware update on the device, this folder is overwritten with new files. |
||
| 15 | If we need to change or copy new library files to roots then we copy these files to /data/firmware/htdocs/python and init_system.py script copy these files to rootfs |
||
| 16 | |||
| 17 | To create new firmware: |
||
| 18 | |||
| 19 | - we change source code files (web files, QT application, External player, init_system script) |
||
| 20 | - change the file /data/firmware/htdocs/version.txt |
||
| 21 | - copy new files to Ubuntu20desk virtual machine |
||
| 22 | - execute from /home/STB folder: |
||
| 23 | ``` |
||
| 24 | tar -cvf application.img firmware/ |
||
| 25 | ``` |
||
| 26 | - copy application.img to https://update.lemco.tv (inside STB folder) |
||
| 27 | - if there is new kernel, copy boot.img |
||
| 28 | - change versions.txt on this location (update.lemco.tv, stb folder) |
||
| 29 | - Now the device can be updated (open web page, and go to firmware menu) |
||
| 30 | - init_system script will download the new file and extract it to /data/firmware |
