Hey, if you guys know about RaQs would you mind helping to diagnose mine? They turns on and all the fans spin, but the display shows a row of black bars and a blank row. Nothing on serial. Cannot get to boot menu by holding S or reset CMOS by holding E. Nothing on serial port (unless the laptop I'm using as a terminal is messed up).
Know what might be causing this?
I had similar issues (display: first row black, second row blank) with my first RaQ 4r after I bricked it by flashing a corrupted firmware image. I sadly confused the wget option -o with -O when downloading the firmware image . Hence I'm afraid your RaQs might have been bricked, too.
The serial console is not active by default, but needs to be activated by pushing and holding the "the little recessed button" (see The Cobalt Hacking FAQ) and then powering on the RaQ. You should see text output on the serial port after the next reset/restart nearly instantly IIRC (I'll check that later this day) after about 8 seconds (with firmware version 2.10.3-ext3 - sorry, no RaQ 4 with older firmware available) . But I'm afraid this might not work at all for your RaQs with the described symptoms.
Just a few guesses:
- Are the capacitors on your board OK? The spare board I ordered for my bricked RaQ 4r board was affected by the capacitor plague. Although mine still worked (at least in the firmware monitor!) with most of the caps bulged, your boards might not, if affected by the same issue.
- What happens if you remove the battery and power the machine on?
- Do you have a load on the 12V rail (e.g. a HDD)? I didn't had the "load" problems I described above for the MIPS based RaQs with my x86 based RaQs, but why not check that out, too?
