Thanks to Dede's hints, the camera was brought to life, the screenshot had to be merged by the programmer, because. the camera itself does not connect on ftp, then everything is done by the run command and one more command uploaded the unpacked firmware via the ftp server and that's it.

I get the impression that without a thread programmer from doing a dump.
Once again, I will play the memory reading in text mode - I changed the amount of scrolling lines into putts, maybe 10 to 6 is enough.
