@diadatp what happened to this? I'm thinking about opening a issue on the https://github.com/EliasKotlyar/Xiaomi-Dafang-Hacks repository to let more people know about Thingino but we don't have T10 support yet.

We support T10 just fine! I have a few =D

T10 is well outdated and the boards we have are noname. If you have an identifiable camera model using t10 soc we can make a profile and add it to the supported list.

for future reference this is a raw list of hardware we support:

Hi, I have this camera with original firmware (from 2017...) Could you try to create a profile for testing? Do you need something? I can try and disassembly the camera.

Here EliasKotlyar/Xiaomi-Dafang-Hacks#625 a lot of info, (board photos, debug, dumps, etc) from previous testing.

Thank you.

Have successfully been using this camera config for a few months now. It works well enough for my needs (live view and occasional recorded view) and is much nicer than the original firmware. PTZ and the typical features you'd expect to work do. Audio out had some sample rate issues that might have been fixed since I last checked.

I believe merging to main was stalled by the unusual alignment (ALIGN_BLOCK = 32K) requirements of my flash chip that goes against the established convention for the other much more recent SoCs. My recollection is fuzzy on this.

In addition the erase size set for the flash chip in the kernel was wrong (gtxaspec/thingino-linux#11) which manifested in a difficult to track down bug (filesystem corruption after first boot).

If there is still interest in this device config, I can pull it together, test against the latest upstream and make pull requests to other related utilities.
