Re: [casper] Error in Simulating Roach 2 Tutorial 1 .mdl file
The axes were not auto-scaled for the adder; you were correct. For the counter, the settings are correct; I just checked them again. Do you have any more ideas on this?

Jack, I'm not able to reproduce the counter output ( https://casper.berkeley.edu/wiki/File:Counter_sim.png) or the Adder Output ( https://casper.berkeley.edu/wiki/File:Adder_sim.png). Instead of those two, I get a line at 0 for the counter output and then just an empty set of axes for the adder output.

[casper] Error in Simulating Roach 2 Tutorial 1 .mdl file
Hello, My name is Christopher Barnes, and I'm a graduate student at the University of Michigan. I'm working through the first four tutorials on the Casper website (located at https://casper.berkeley.edu/wiki/Tutorials) to program a ROACH2 as a wideband pocket correlator. I've finished building the .mdl file from the first tutorial, and my output from the scopes did not match what is displayed on the webpage, so I'm requesting some help with this. I'm a beginner, so I'm not sure what the problem could be aside from the cookbook instructions on the website. If you're willing to help me, then please email me back and I can show you my file. My suspicion is that the discrepancy between my output and the output on the webpage is caused by an outdated release of the tools in Simulink.
[casper] Connecting to ROACH2 via USB and Ethernet
Hello, My name is Christopher Barnes, and I am a new graduate student at the University of Michigan. My current project is programming a ROACH 2, and I've been having a fundamental problem in getting started. As recently as two weeks ago, I was able to connect to my ROACH over the serial connection program 'minicom' and use the 'telnet' command over an ethernet cord. Last week, both of these functionalities did not work. Is there anything basic that I could have broken with the software that could have caused this problem? Establishing one of these two connections is essential to moving files to the ROACH 2 in order to program it. Any help given on this subject would be greatly appreciated. Thanks, Chris
[casper] Mounting an SD Card on a ROACH 2
Hello, My name is Christopher Barnes, and I am a new graduate student at the University of Michigan. I've been starting to program a ROACH 2 for eventual use as a wideband pocket correlator, and I am emailing to ask for help with this. I am using a python script to upload .bof files to the ROACH, but once they arrive they have no contents. This is because the root file system on the ROACH has no storage. I am trying to mount a 64 Gb SD card onto the ROACH for extra storage in the root filesystem, but the Casper documentation only gives information on how to boot the ROACH off an SD card. Any help that anyone can give with this is greatly appreciated. Thanks, Chris
[casper] Using katcp to Communicate to ROACH 2
Hello, Similar to Victor's email earlier today, I am writing to ask for instructions on using a ROACH 2 with a PC terminal. I can communicate with the ROACH 2 via a telnet connection, but I am unable to transfer and execute boffiles to the board. Also, I am unable to complete the tutorials listed at the following link, https://casper.berkeley.edu/wiki/Workshop_2011_Tutorials, because my PC does not recognize the ROACH as a hardware platform. Help with either of these issues would be greatly appreciated. Thank you, Christopher Barnes
