Re: [casper] Programming a ROACH2

I think the intent of exit_fail() is to try to close the connection, ignore any exceptions raised while trying to close the connection, and then re-raise the original exception that happened before exit_fail was called, but I think the implementation is flawed. Here’s the definition of

Re: [casper] Programming a ROACH2

Some of the earlier scripts had bad error handling. If anything fails before the host object was successfully created, then you get this error because it tries to close the connection before exiting. Jason On 11 Oct 2016, at 16:09, David MacMahon wrote: > >> On Oct 11,

Re: [casper] Programming a ROACH2

I can't answer the question directly, there is a C utility which will program fpg files into roach2s, called kcpfpg - it lives on github in ska-ska/katcp_devel - run the toplevel makefile then cd into fpg and there should be the utility regards marc On Tue, Oct 11, 2016 at 12:56 PM, Heystek

Re: [casper] Programming a ROACH2

Hi I am now trying to do this manually line by line through ipython. Do anyone perhaps know what is the equivalent for the roach2 of the following function? fpga.progdev() a_0=struct.unpack('>1024l',fpga.read('even',1024*4,0)) a_1=struct.unpack('>1024l',fpga.read('odd',1024*4,0)) On Tue, Oct

Re: [casper] Programming a ROACH2

Hello Heystek, Having looked at the tut3 which is on the website, it is using the older corr library, not casperfpga. It also looks as though it's intended for ROACH and not ROACH2, I'm not sure whether that's an issue. I've never used a ROACH2. I was under the impression that it should have

Re: [casper] Programming a ROACH2

Hello Heystek, How cognisant are you with Python? Try opening an ipython session and connecting to your ROACH manually, I think you have been able to do that in the past. This error message means that your network can't reach the ROACH for some reason. Regards, James On Tue, Oct 11, 2016 at

Re: [casper] Programming a ROACH2

Hi Everyone After trying all of your suggestions and install a few more packages is works. I get the following error now when I run the tut3.py script for tut3. heystek@heystek-HP-G62-Notebook-PC:~/simulink/heystek_tutorial_3/heystek_tut3$ ./tut3.py 192.168.33.7 tut3.bofConnecting to server

Re: [casper] Programming a ROACH2

I would suggest using "pip uninstall spead" instead -- I don't recall ever using it myself, but it appears to be the pip-sanctioned way of removing something. On 10/07/2016 02:24 AM, James Smith wrote: Hello Heystek, Pip is seeing that you've already got a version of Spead installed, which

Re: [casper] Programming a ROACH2

Hello Heystek, Pip is seeing that you've already got a version of Spead installed, which might not have worked. You can delete the directory to 'uninstall' it (Request for comment: is this a safe approach? It's what I've always done with no problems.) Before you try that though, perhaps just try

Hello Heystek, I vaguely recall installing spead from pip as well, as Ryan has done here. Give that a whirl. Regards, James On Fri, Oct 7, 2016 at 11:06 AM, Ryan Monroe wrote: > rmonroe@rmonroe-ThinkPad-P50:~$ sudo pip install spead > [sudo] password for rmonroe: >

Hi James I installed the PySpead package but I get the following error when I run the tut3.py script: ImportError: No mode named spead Do you perhaps have any ideas on how to solve it? Thank you!! Heystek On Fri, Oct 7, 2016 at 11:01 AM, James Smith wrote: > Hello

Re: [casper] Programming a ROACH2

Good Day After a while of troubleshooting I determined the connection with TCP/IP into the board was correct. I updated the file system and kernel of the ROACH2 and now I can program it. I only need to install a package called spead in order to use the .bof file with tutorial 3 of CASPER. Where

Re: [casper] Programming a ROACH2

Hi Heystek, If you want to telnet, which is another way of configuring your board, then you need to state the port. Are you doing the following from the terminal: 1)Telnet to port 7147: "telnet 7147". 2)?progremote fpgfile.fpg You say you can ping your board, so you should be able to connect

Re: [casper] Programming a ROACH2

Hi James I will try it. Through the terminal I can ping the board, but I cant open a Telnet connection. When I open a ttyUSB connection to the Roach en monitor it, and try to upload the fga file, the Roach gives the same error "progremote" Thats why I'm confused Thanks for your help! I really

Re: [casper] Programming a ROACH2

Hello Heystek, Before you program the ROACH2, I'd suggest trying fpga.is_connected() and fpga.est_clk_frequency() to check whether you can actually communicate with the ROACH2. It might be a network cable that's been unplugged by accident - that's where I've seen those errors before. The
