I also use Ubuntu 14.04 LTS and for my V3 borad I have to use drsosc 4.x or ealier to perform the calibration.
1) I tried to cablirate a V5 board with drsosc 5.0.3 and it just worked fine for me. No idea what went wrong in your case.
2) The "found 4096 stuck pixels on this board" can be safely ignored. It comes from the fact that the standard evaluation board has four cannels unconnected (the DRS4 chip has 8 channels, four are connected to in the evaluation board and four are unconnected). So the software sees wrong values on four channels because they are unconnected and thinks something is wrong. Unfortunately the software cannot determine if the channels are connected or not. So just ignore it.
3) I heard several people having to reset their boards under Linux in a similar way than you. This is probalby due to some instability in the USB part of the linux kernel, since the problem does not occur on other systems (Windows, Mac OSX). So I cannot do anything from the software side.
I`m trying to calibrate my DRS4 evoluation board to an input range of 0-1V but it doesn`t work.
1) First I tried to calibrate it with the drsosc (version 5.0.3) Software. The -0.5V - 0.5V calibration works, but during the 0 - 1V calibration the Software crashes.
2) I also tried to calibrate the input range with a C++ DAQ Package (based on drs_exam). Here the code of the calibration:
b->SetInputRange(0.) (Center at 0 V )
b->SetInputRange(0.5) (Center at 0.5 V )
Results in: Found 4096 stuck pixels on this board.
Did I do a mistake or is this a normal behaviour of the board? Also the board often crashes and I get a magic number 0000 after restarting the DAQ. Then the board needs to be restarted via pulling the plug. ( I ensured that I terminate the USB connection before I close the program with "delete drs"). Is there a possibility to avoid this error?
My OS: Ubuntu 14.04 LTS.
