UNFEX REFEX FWINFO, Allwinner V3(s) action camera, shell scripts for Linux

[petesimon]

This is a work in progress ... when I have free time. I need your help. If you are a Linux user, please contact me.

Scripts are .sh file for running in Linux. They are based on various .bat and .cmd scripts from this post #30 https://www.goprawn.com/forum/allwin...?p=839#post839 . Be sure to install 'squashfs-tools' and 'java-common' packages. The 'openjdk-11-jre' package for java may also work. Read the ' readme txt ' file inside each downloaded archive file.

These scripts are only for 12058624 bytes size full_img.fex files. Scripts for the 3 to 4 other common sizes of full_img.fex files are not yet available.

Download all together in an archive tar.gz here - https://drive.google.com/open?id=1Zd...AqB4x87a92bTmA

Individual .sh and other files, download here - https://drive.google.com/open?id=1oO...IZnofKHRR47Spq

Available scripts as of now:

Open a Terminal application window.

Run 'bash ./unfex.sh' to create separate 0/1/2/3/4/5/6 partition img files.

Run 'bash ./squashfs_unmake.sh' to extract data from 2-system.img partition file.

Run 'bash ./scriptbin_read.sh' to create script.bin hardware description file.

Run 'bash ./convertscriptbin.sh' to get script.fex readable text.

Run 'bash ./refex.sh' to create a FULL_IMG.FEX file from 0/1/2/3/4/5/6 img files.

Run 'bash ./squashfs_make.sh' to create a 2-system.img file from data in 'squashfs-root' folder.

Update: 'fwinfo.sh' script added. Download here - https://drive.google.com/open?id=1Zd...AqB4x87a92bTmA

Open a Terminal application window.

Run 'bash ./fwinfo.sh' to get firmware info. Look in a FWINFO folder. Open 'fwinfo.txt' file.

I’m a long time linux user who is trying to do stuff with these cameras. I have a few to try out.

[petesimon]

Great. Please here describe your cameras and describe your Linux setup (Ubuntu, Fedora, or another).

I've got three types of allwinnerv3 cameras. All are similar but only one has the touch screen. I've managed to get firmware for 2/3 and I'll try the third today. I mostly use Ubuntu but I have a Debian install as well. I am running on some amd64 SoC and hoping to configure the cameras to stream live data to the linux machines.

*Update* I am unable to backup the fw on my newer camera. In the config screen the version reads as 20200101 v001. It won't show up when I run ./backup.sh

error: no devices/emulators found
Device not found. Check camera and USB connection and try again

lsusb reports the following:
Bus 001 Device 006: ID 1908:1913 GEMBIRD




This is the info for my OTHER camera that I was able to pull FW from:

thanks for the info! can you please share your firmware here by dropbox or google-drive ?

lsusb reports the following: Bus 001 Device 006: ID 1908:1913 GEMBIRD

also, I guess that a 1908:1913 GEMBIRD may not be an Allwinner V3 device, but I could be wrong. Check the Linux USB ID database here - http://www.linux-usb.org/usb.ids

The seller claimed they were AllWinner v3 camera and they look just like them but they don't seem to present anything to the android debugger. I tried setting udev rules like the ones in the script but with 1908 1913 as the ids but no luck.

[petesimon]

In the config screen the version reads as 20200101 v001. It won't show up when I run ./backup.sh

Can you take a photo of the firmware info screen of the camera, and share that photo here?

also, you could try do these commands in the Linux terminal (console) one-by-one. be sure that 'adb' and 'zip' packages are installed and your udev rules are correctly configured for Allwinner V3 USB devices. and later share the backup.zip file via google-drive or dropbox.
