Rooting around in the Longse / Cantonk S2L33M/IMX322 vari-focal camera.
- Thread starter alastairstevenson
- Start date
Thank you, alastairstevenson!
I was able to do this and set up the Internet on the camera.
But I can't download mtd4, 5 and 6. At some point there is a failure.
Maybe there is not enough space in the memory of the device? If this is the case, will you have to configure the NFS server?
What say you?
The log is attached.

From the log it looks like /etc/init.d/rcS is not enough by itself to fully initialise the running environment.
Startup tasks tend to be distributed in different ways in different implementations of embedded systems.
Suggestion:
To check if all is normal, use the commands
mount
and
df -h
There should be no errors, and a list of mounts should show, and the space used on them.
If there are errors, the full startup has not yet been done.
Another place to look in in the file /etc/inittab
Check out the contents using
cat /etc/inittab
Look for lines such as below, which would be part of startup processing.
null::sysinit:/bin/mount -t tmpfs tmpfs /tmp
There may also be a line that runs /etc/init.d/rcS
If there are lines like that in inittab you will need to execute them manually.
This is easy to do if you use the PuTTY 'copy all to clipboard' item from the top left menu.
You can paste the result into Notepad or similar
Then gather together the lines to want to execute, copy them to the clipboard, and paste into PuTTY.
This saves typing them, and removes typing errors.
Once you get to a proper running system, you should be able to bring in the files you need without running out of space.
Again - I'd suggest that you do not attempt to write the bootloader and the system partitions mtdblock0, 1,2 and 3
These are working OK and if corrupted will permanently brick the camera.

Oops - my mistake, sorry.
I forgot to mention that you need to trim the lines in inittab before using them manually at the command line.
So quite a bit of the startup is in inittab and not all in rcS
That explains why mount and so on do not work.
This is the relevant part of inittab:
Code:
# Startup the system
#null::sysinit:/bin/mount -o remount,rw,sync /
null::sysinit:/bin/mount -t proc proc /proc
null::sysinit:/bin/mount -t tmpfs tmpfs /tmp
null::sysinit:/bin/sh /etc/ambrwfs
null::sysinit:/bin/mount -a
null::sysinit:/bin/echo '\000\000\000\000' > /proc/sys/kernel/hotplug
null::sysinit:/bin/hostname -F /etc/hostname
null::sysinit:/sbin/ifconfig lo 127.0.0.1 up
null::sysinit:/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo
# now run any rc scripts
::sysinit:/etc/init.d/rcS
null::once:/usr/local/bin/upgrade-d/bin/mount -o remount,rw,sync /
/bin/mount -t proc proc /proc
/bin/mount -t tmpfs tmpfs /tmp
/bin/sh /etc/ambrwfs
/bin/mount -a
/etc/init.d/rcS

You might be able to skip doing rcS which should avoid it trying to start up the main apps and giving errors.
Just check out what can be done in terms of getting the needed flash partition loaded in before executing rcS.
Hello, alastairstevenson!
I tried this and also tried the netcat and did something bad for the camera... Now I can only get Amboot and can't get to the root console.
What can you tell me in this case? Do I still have options or not?

I'm not sure what you did with nc. What did it attempt to transfer in?
The original idea was to see if you could boot to a shell and find if tftp was available.
It was, and could therefore be used to bring in a saved partition image from another camera, to be applied to this camera.
Something like
cat file_that_was_loaded_in > /dev/mtdblock4
It looks like mtdblock4 and mtdblock6 have been written over such that they are no longer valid UBIFS images.
On the attempt to repair via the bootloader - the NAND reclaim looks promising.
If the NAND subsystem in the bootloader does allow writing of specific partitions from images that have been loaded in using tftp, there may me a chance of re-writing with valid data.
This command -
tftp program mtd6 0x08000000
requires an additional parameter (a 0 at the end) to tell the bootloader that the data is not a program to be executed
tftp program mtd6 0x08000000 0
But I'm not sure what the NAND command would be to write the data to a specified partition.

That worked OK, and loaded the file into memory as it should.
The next step would be to write that data to the correct area of flash memory.
But it's not obvious if the available NAND commands can do that, or if it's the 'nand prog' command that does that, how to use the command-line parameters. It would seem logical that if there is an erase command there should also be a write/program command.
The normal steps would be a 'nand erase' to the specified offset and size to initialise the flash, then a 'nand write' from the memory that has been loaded to the same offset.
But there doesn't seem to be a nand write command.
I can try nand prog with my hands, but I don't understand how this command works... It is not clear what the [BITFLIP] parameter is...
And I don't know what pages I need...
I am ready for any experiments, but unfortunately I do not understand much yet...
Ready to test any of your idea if you are not too busy.

Ready to test any of your idea if you are not too busy.
But as I can understand from the logs, into which slot do I load, for example mtd4?
Here mtd6 I load at 0x08000000. Where is this information?
Is it?
I have not met in the logs references to 08000000.

That's a memory (RAM) address.
The 'lnx' partition is mtdblock4
Those addresses in the partition table are flash offsets, not memory addresses.
To use them requires an app or command that can read and write to the flash chip.
Hello, alastairstevenson!
Thank you for helping me.
I was able with the help of your tips to recover a single "brick".
And now I'm facing another problem on another camera. I tried to flash a new firmware, but something went wrong.
The method that approached the previous camera does not work here.
The log is attached.

All, was able to solve this problem.
The problem was that when you switch to the new firmware, you first need to flash the bridge firmware, and then through The regular ipcsearch utility.exe to flash new firmware.
My version of IPCsearch.exe could not do it, but the older version could.
alastairstevenson
Staff member
Well done!
What was the final method to put the firmware back together again? Via a bootloader command?
Yes, I think the 'bridge' intermediate firmware includes a kernel update.
The method worked the one you described:
1. boot console=ttyS0 ubi.mtd=lnx root=ubi0:rootfs rw rootfstype=ubifs init=/bin/sh
2. /etc/init.d/rcS
3. ifconfig eth0 <camera_IP_address> up
4. ping -c X <your_PC_IP_address> (where X = number of required packets (otherwise the ping cannot be interrupted))
5. cat /etc/inittab
6. /bin/mount -t proc proc /proc
/bin/mount -t tmpfs tmpfs /tmp
/bin/sh /etc/ambrwfs
/bin/mount -a
/bin/mount -o remount,rw,sync /
/etc/init.d/rcS
After that, the camera was able to boot properly and I was able to find and flash it through a web browser.
But it worked only with the camera, which can be accessed in the root console.... I have 2 cameras in which there is no download and which have a root console not available.
And there are 2 more cameras where I experimented with NAND" killed " Amboot...
Now no aktivnosti UART camera not give.
