Re: [casper] Roach-2 crashing fix

So I confess to relying on third parties for this information, but isn't the board populated with 1Gb RAM after all ? Would the crash be trigged by a kernel memory layout of 3Gb+1Gb rather than 2Gb+2Gb ? Have you tried the kernel from 9 months ago at github ska-sa/roach2_nfs_uboot ? regards

Re: [casper] ROACH2 one_gbe block losing data on reception

Hi Henno, Thanks for replying. I meant to mention the simulink clock is 250 MHz and the design meets timing. The ultimate goal is loading waveforms into the DRAM since there isn't a CPU DRAM interface for ROACH2 yet, so any speed better than loading via KATCP would be great. But I've tried delays

[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

Re: [casper] ROACH2 one_gbe block losing data on reception

Hi Glenn, Everything seems to be in order, however if there was signal integrity issues the MAC (temac) would report bad frames due to CRC failure (the CRC is calculated over the entire Ethernet frame). Just another sanity check would be to send this data to another PC and just confirm that all

[casper] Communicating to ROACH 2

Hello everybody, I'm writing to ask you some detailed guidance to communicate my linux PC to the Roach 2 board.I have the Simulink project compiled successfully and I'm able to watch the u-boot process on minicom terminal. However, I don't know how to proceed at this point. May anybody provide

Re: [casper] Communicating to ROACH 2

Hello Victor, Are you planning on using telnet or python? If python, check out the casperfpga module on ska-sa Github. It's not documented in the tutorials unfortunately, and it takes a little bit of doing to install, but once you're there it's very easy to us, especially with ipython. I've
