| Voltcraft DSO-1062D crashing |

Hello Guys. First of all: I appreciate all your help! I got 2 Voltcraft DSO-1062 Oscilloscopes in our laboratory at university and both of them share exactly the same Problem: They are always crashing. This happens randomly but really often like every 5 Minutes or so. Now I figured maby a firmware update could help. But since im seeming to be running on an old firmware 2.06.3 it looks like I cannot update it via usb. I tried several old usb-sticks just to make sure a bad usb stick is not an option. I always get the error code 0xff - no usb device found. I've been searching for 2 days now trying to fix this thing but I cant find a way to update the firmware. I already tried to follow the tutorial from another post (https://www.eevblog.com/forum/repair/voltcraft-dso-1102d/msg2036896/#msg2036896) but at one point I figured that the file structure of my oscilloscopes seems to be completely different from what he described. I guess I, to all extend, already fried one of them because that thing is always rebooting without pause. So I would be glad to get some adviced of what to do now. Thanks in advance. |

What's the size of those memory sticks? Seem to remember from other threads that for some scopes it needs to be 1-2-4GB. |

I tried different shapes and sizes but to be honest I cant remember which ones exactly. Im gonna search for one thats fitting in that category to test it. EDIT: Tried a 1GB stick now. Doesnt work unfortunately |

I think I got something. The advise with the USB-Stick has let me redo the work of the former mentioned post. So yes the reason why that didnt work was really the USB Stick. But unfortunately there seems to be a problem with my memory. --- Code: ---[root@Tekway-dso /]# /tmp/tekwayup_client/packet/do_update.sh cp: write error: No space left on device cp: can't create directory '/etc/mdev': Cannot allocate memory cp: can't create '/etc/mdev.conf': Cannot allocate memory cp: write error: No space left on device cp: write error: No space left on device cp: write error: No space left on device cp: write error: No space left on device cp: write error: No space left on device cp: write error: No space left on device [...] --- End code --- But "top" says --- Code: ---Mem: 29596K used, 31816K free, 0K shrd, 120K buff, 23792K cached CPU0: 0.0% usr 0.1% sys 0.0% nic 99.8% idle 0.0% io 0.0% irq 0.0% sirq Load average: 0.00 0.00 0.00 1/19 695 PID PPID USER STAT VSZ %MEM CPU %CPU COMMAND 371 1 root S 1824 2.9 0 0.0 -/bin/sh 695 371 root R 1800 2.9 0 0.2 top 1 0 root S 1796 2.9 0 0.0 init 566 1 root SW 0 0.0 0 0.0 [usb-storage] 2 1 root SWN 0 0.0 0 0.0 [ksoftirqd/0] 4 1 root SW< 0 0.0 0 0.0 [khelper] 27 5 root SW< 0 0.0 0 0.0 [khubd] 3 1 root SW< 0 0.0 0 0.0 [events/0] 5 1 root SW< 0 0.0 0 0.0 [kthread] 25 5 root SW< 0 0.0 0 0.0 [kblockd/0] 40 1 root SW 0 0.0 0 0.0 [kapmd] 73 5 root SW 0 0.0 0 0.0 [pdflush] 74 5 root SW 0 0.0 0 0.0 [pdflush] 76 5 root SW< 0 0.0 0 0.0 [aio/0] 75 1 root SW 0 0.0 0 0.0 [kswapd0] 150 5 root SW< 0 0.0 0 0.0 [kseriod] 200 1 root SW 0 0.0 0 0.0 [mtdblockd] 461 1 root SW 0 0.0 0 0.0 [scsi_eh_1] 562 1 root SW 0 0.0 0 0.0 [scsi_eh_2] --- End code --- Any ideas about what I possibly could do now? |

I owned one of these for a short time, not long enough to get familiar with the memory structure. Can waveforms be saved to internal memory or is it only external USB? If internal memory is full with user data try emptying that before firmware update although it would make sense that a sufficient partition is reserved for firmware. |
