You seem awfully intent on dimissing my hypothesis. Were you part of the dev team or something?

Ive been quiet on this thread so far, but Dragos, what is the hypothesis? I think Hector and others are showing you the data and procedure (however indirectly) to test your hypothesis.

hypothesis is that RF noise is being injected into dwc_otg

and audio pwm is being used to transfer data in and out sdr style after.

This is a textbook case of confirmation bias. You are ignoring facts from experts as they are not the explanation you would like to hear. In combination with not making a single filesystem dump available anywhere it becomes impossible to reason with any of your analysis.

How many of your raspis have an mmc1? I can give you a file system dump but it won’t help much as the fun stuff is loaded into a ramdisk from inaccessible hidden partition and only the unmodified components are available to dump. Offline forensics won’t make much headway.

It's not appropriate to call someone paranoid an idiot, though. Your arguments are strong enough, no need to insult.
