Now with 12mm macro. Better focus, and much lower chromatic aberration. Yes is it askew. I need to 3D print a new camera mount, as the 12mm needs to be 5mm higher.

Resolution hack update V4. Type C firmware attached I wasn't able to limit the size of the H264 compression buffer, but by dropping the processing resolution to 1600x1200, on was able to fit one of the two buffers lower in memory, and now have no conflicts. The bit-rate control was struggling...

Resolution hacking updates. I was finally able to move the input buffers so that will not collide with each other. This took ages to work out, as there are multiple areas that the read and write these buffer addresses, some seem to be within interrupts. So I can now capture 1920x1440, process...

Looking for the AE is hard, and there doesn't seem to be any active error messages in that code. It might be near AWB, but I haven't looked hard for it yet.

Slow slow progress. I believe the function FUN_002f5094() set up the addresses for the two capture buffers, as it has these telling error logs: ERR:%s() Input buffer0 Y channel address - 0x%08x ERR:%s() Input buffer1 Y channel address - 0x%08x This function is called at the video frame rate...

128MB has been confirmed, as the memory repeats at the 128MB boundaries. 1Gb = 128MB

Today's progress. I did a series of captures, erasing the memory between captures so I could more easily see how the memory was being used (from the shell: mem fill 82000000 04000000 ff). Each capture use a different source resolution, all encoding to 1920x1440. The encoding resolution is not...

Thank you. "Built-in 1Gb DDR3 SDRAM" , now triply confirmed. This feature sheet is good to see.

Something doesn't quite add up, which where the video corruption could be coming from. Here we see Luma data straddling 0x06000000. Yet on the console there is this info: H264 is initializing something at 0x060A55C0, which in the middle not the top a the frame buffer. This address doesn't...

I also found the NT96655, I hoped to find what the differences are to the 96658, as the 55 doesn't have integrated RAM. I think I'm over my confusion able the tiny RAM size. There seem to be plenty of unused memory. Here is an crudely annotated memory dump during 1920x1440 capture (1920x1440...

Thank you @Mac84 and @wnt2fly. I going to proceed assuming the memory integrated and only 128MB. Crazy how there are no leaked datasheets for this obsolete part.

I'm diving into where the frames are stored in memory, and have run into a new question. When the system boots it reports: I always read that 1024 as 1GByte. Yet that Mb <- seems to be Mbits. Only 128MBytes, that is tiny. Does anyone have the parts list, or images on the underside on the...

I have now proven this hardware is capable for a 2K scan (1920x1440). Now while it is has issues, major glitches, this is a pixel of pixel encoding at 1920x1440, no interim scaling. I'm seeing details that have never showed before, the sharpness of the sprocket edge, and one pixel thick...

what happened?

Yes, an Enter key will get me a prompt >

Seem the RX might not be connected. This is my current console output.

In the PuTTY Terminal configuration set Local echo to "Force on" works for me.

@Hawke this is excellent news. I have determined when initializing the preview from the function at 0x2bf908, the corner offset and capture image size and followed by the processing resolutions. For max zoom out. This data return by 0x2bf908: 732 452 840 632 840 632 1260...

Have my new macros. Surprisingly does get the film mostly in focus, some edge softness. However, is confirmed my fears that there is something else limiting the resolution of this system. So while new lens has almost perfect coverage, it is not improving the resolution as expected, there still...

Seems my new macro lenses are potentially held-up in customs. In the meantime here is the latest build (type C) where you can use the existing reframing controls to scan everything the sensor sees. This is great for hardware hack that want to do 16mm scan with the existing lens, or replace the...
