Why?

SPK+ - will most probably be for speaker.
DM, BOOT0 maybe interesting, not really sure offhand unless you take a look and see what signals are coming out of either..  GND will be ground.

Whats on the other side of the board?
What SoC is it using under the heatsink? (the big block above PZ1)

My usual method will be to check what the SoC is, and try see where the UART pins lead.


This camera - right?

See if you can find some firmware that we can look at also.  That will give more clues.  It's probably ARM based.

What does the flash branding say?  I think its a Winbond, but not 100% from the photo. (its left, above the TEAN E120339 writing)
At a guess, its likely SPI flash, as I only see 8 pins,  but a better shot of the model number would help.

Possible its only 2.4ghz, but an N wifi will be able to connect to that

If you've nuked the uboot, will need an spi flasher or similar to reflash.

Have a look at the forums for routers eg (dd/open)wrt, as people do that a lot, and its described in more detail than I'm willing to type :)

N745, so Pin 10, 11 are typically serial out.

Follow those pins from the cpu (the circle on the N745 indicates pin 1) and see where they go to.
Or use a multimeter in beep mode and buzz out those 2 pins with the socketed ones and see if they're connected anywhere.

HiSilicon media processing platform (HiMPP) is part of the SDK.

You'll need to either have bought a dev kit, or trawl the internet to find the SDK.

Maybe check this blog -
https://mark4h.blogspot.com

This post talks about it in
https://mark4h.blogspot.com/2017/07/hi3518-camera-module-part-1-replacing.html
and this has a link

https://github.com/shadow-1/yi-hack-v3/issues/23
From that Link - https://app.box.com/s/cibs7n1mgvhqaqjlidtveegu1uajt5yr
Note - Finding a specific version is probably impossible unless you have legit access, so you'll have to make do with whatever has been previously uploaded.

@rickHarley, don't post irrelevant link spam, or you'll be banned.

@corvairbob.

Analog camera quality will be based on how many lines they have, usually indicated by TVL in the camera description. 
Higher numbers are better.

Look for a low angle lens if you need a wider angle view. For a small room, it will need to be very low angle!


To be honest, I don't think you'll get what you want with analog camera's, as the quality isn't going to be there, even with the best lighting available.

Interesting.

There's a series here too that I wrote many years ago - https://www.computersolutions.cn/blog/category/ip-cam/
9 years ago!

connect directly to the webui of the camera on its ip address?

have had a quick look, but github loads terribly slowly in china., if you're referring to j3.jpg 左右 that means left right

gm8126 for bt mining? hah, woefully underpowered

Site Announcements / Forum update

Possibly seeing some failed hack attempts, as the settings file was getting erased blocking the site for a day or two.
Updated forum software to latest version, and will monitor for further issues.

uCLinux / Re: Fix KRACK ATTACK in ARM Linux
« on: November 23, 2017, 11:29:43 pm »
wpa_supplicant version 2.4 and above is affected, so replace that.

That said I'm not actually sure that the version on the camera is vulnerable, it might actually be too old.

Firmware / Re: Recovering Siepem S6211-WR - Ingenic T10 based
« on: August 21, 2017, 08:15:37 pm »
Haven't seen an ingenic SoC in a while.  One of the few MIPS processors left in the market, everything else is ARM...
Have done a bit of work on their older stuff (JZ4755 SoC), good documentation, shame the company got bought out.

Boot shows
[    0.936018] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)


Make sure you have a valid root file system wherever it needs to be in flash.
Not much clue where it should be from this (although we do have locations for other stuff).


Top of RAM usable for U-Boot at: 84000000
Reserving 402k for U-Boot at: 83f98000
Reserving 32784k for malloc() at: 81f94000
Reserving 32 Bytes for Board Info at: 81f93fe0
Reserving 124 Bytes for Global Data at: 81f93f64
Reserving 128k for boot params() at: 81f73f64


Suggest check in the uBoot to see if you can list partition locations, and work out where a FS ought to be.
You'll then need to make one, and copy over to the uBoot software to flash.

See what uBoot commands you have in order to check first.
Also suggest read up about uBoot.

Firmware / Re: Hi3516 Unknown command 'root' - try 'help'
« on: July 28, 2017, 01:42:11 pm »
Suggest read the uBoot docs for what is (possibly) available.

http://www.denx.de/wiki/view/DULG/UBootCmdGroupInfo

a uboot is a preboot that loads the OS
You will need to see if you have an OS on your board to boot into.

I'd try some common commands like
help
ls
flinfo

and try see what partitions you have etc

Firmware / Re: U-boot corrupted. Looking for recovery procedure
« on: July 28, 2017, 01:36:53 pm »
Whats the SoC?

Some of the more modern SoC's can do recovery via USB boot.
If not, you'll need an SPI flasher or similar to rewrite the uboot directly onto the flash, eg with a BusPirate or dedicated device.
