Rohde FSEM hangs on startup
« on: September 21, 2022, 10:31:44 am »
Hello,

I have a FSEM  that boots correctly but hangs on loading the transputers, I replaced the CPU card with my other FSEA, boots fine and loads all the modules. Any clue what that can be?

Addind picture of the CPU card (bios 3.3)  and where it hangs

Likely some problem on the Address/Data bus that goes to the other modules - guess you have no schematics of this board?

I now have a ZVRE which has a similar problem it boots, but hangs most of the time at the splash screen. I get some transputer download errors. Unfortunately i don't have another CPU board to test whether that is the same problem as you have. I posted report here: https://www.eevblog.com/forum/repair/rohde-schwarz-zvre-hanging/msg4432519/#msg4432519

I'd start by re-seating (removing / plugging back in) everything that is fitted in a socket.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
