Why don't you help us?

All you need is some courage to start following the notes. Browse the docs. Start poking around and write down what you discover. That's pretty much it; we don't really know what we are doing either.

I've just got a Raspberry Pi Zero (ARMv6) to try the above debug registers, but didn't power it on yet. You've got the real hardware; maybe you can read the thesis linked earlier and try to reproduce some of the results. Or maybe you can try something easier, like playing around with the logging code. Or try to figure out how to print some stuff on the screen. Watch this video for a nice intro. Just some ideas.

Hi all.

Been watching and playing for a while with some others who are studying software development at uni and we would like to get ML on the 80D as a fun but challenging project. We've taken the 80D apart and posted some photos of the main board. If we missed something let me know as there are a few more we took, or we could take it apart again if we really need to (may have to if we need to find anything out about the NFC chip).

Hopefully these photo's will help with something.

Very nice pictures, thanks!

If anyone identifies some circuits, you are welcome to edit the Datasheets page. I'll start with the most obvious ones:

- AD80334 BBCZ (ADTG, likely custom chip designed for Canon by Analog Devices)
- Elpida B8164B4PR (8Gb SDRAM; this camera has 1GB RAM)
- F74965A: MPU, same as 5D3

According to this page
Quote
AD80334BBCZ
4 CHANNEL, 14 bit , 50MSPS AFETG+PPP

80D sensor has no ADC onboard?

Congrats on these photos, they are very clear.

I'm surprised to see that there is a button cell there, but it cannot be changed by the user...

The MS614 is a rechargeable button cell, probably there only for timekeeping when there is no battery in the camera.
Since it's rechargeable, no need for user replacement...

Oh, I did not know that, thanks!
