Unsuccessful root of CW-036/CW-236

[bi-os-050]

I have tried a lot here, I really do not know what is wrong with this setup.

Essentially, I have either model CW-036 (According to the mobile app) or CW-236 (According to the sticker). No matter what I try, it won't open any more ports (stuck on the service port / 6668) or create the "hack" file.

I connected to the UART pads:

Saw a different load address too, modifying the "env" and "ppsMmcTool.txt" files with that one didn't change anything?

ppsMmcTool.txt

style=upgrade,,writeAddr=0,,password=nothing,,writeLen=0,,fileName=env;env import 80008000;saveenv,,

env

hack=setenv bootargs ${bootargs} '- ip=30;/mnt/mmc01/initrun.sh)&:::::;date>/tmp/hack;(sleep
ipaddr=0;run hack;bootm 0x80008000;

And here is my SD card contents: mmc.zip

In the app, it says my camera's firmware version is "V33.50.30", sounds off.

Tried 2 different SD cards, a 32GB and a 16GB, both MBR/FAT32.

@bi-os-050 are you able to 'pause' the boot process by pressing any key when it shows Hit any key to stop autoboot: 1 at the beginning of the log ? if so, send me an email (my email is on my github profile) and I can try to give you some pointers for the boot loader.

Looking at this log this appears to be a whole new camera (different from the ones we have seen before) with a new boot loader (dated Jan 5th 2023) which likely has different scripts + settings so it it's understandable it may not be compatible with the process we've made for older devices.

One question: was the log above done booting with the reset button pressed (to initiate the parsing of ppsMmcTool.txt + env file ? I'm asking because it looks like a normal boot and a log with the reset button pressed would likely give more insight as to how it tried to process the files.

If you can't pause the boot to go into the boot loader the only way to move forward would be getting a dump of the firmware which requires a hardware programmer, removing the chip, etc -- I don't expect you to risk breaking the device but if you do get a firmware dump let me know and I'll take a look when I have a chance.

I have a CW248 with the same firmware version. I'm having no luck (to the best of my knowledge) getting it to boot properly, but I have NOT opened the camera up yet, as I'd rather just return them rather than risk being forced to keep a pair of cameras I can't disable cloud and disable recording on.

I'm open to suggestions as to how to move forward.

[guino]

@WhoDunDidIt that's what I usually say: If you can get a device that has RTSP out of the box (at comparable prices) you're better of doing that than spending a lot of time/effort in trying to add RTSP to it. Some people like tinkering with this stuff and/or like the challenge OR already have a device sitting around, but otherwise if doesn't suit your needs you should return it if you have that option.

CW-036/CW-236 Hello everyone, does anyone have the dump of this camera?
