[casper] reading and writing to BORPH

Hey guys, I'm trying to read and write to a ROACH1 using the BORPH filesystem. I followed the tutorial at https://safe.nrao.edu/wiki/pub/CICADA/FlashLights/BorphGettingStart.pdf, but got somewhat different results root@roach:/boffiles# ./asmls_roach0_2013_Mar_15_1123.bof ^Z [1]+ Stopped

Re: [casper] reading and writing to BORPH

i assumed the register was a 32bit word but didn't expect you to read x00x back out! that is werid! have you tried the ?wordread and ?wordwrite commands from tcpborphserver? also try echo -ne to ignore the trailing newline. maybe there is some borph kernel weridness is there anything in dmesg?

Re: [casper] reading and writing to BORPH

Hi David, thanks for the response! I guess I wasn't really sure which ioreg_mode value corresponded to which, so I just tried them both. So <1=binary> and <0=ascii>. Armed with that knowledge (plus your mad BASH chops), I successfully controlled some registers through BORPH. Still no luck in

Re: [casper] reading and writing to BORPH

You can only use tcpborphserver's katcp interface if you program the FPGA through that too. If you program the FPGA "behind its back" (ie from the command line), then you can't read/write registers over katcp. I strongly advise you to use katcp in your new design, because BORPH is not provided

Re: [casper] reading and writing to BORPH

It's okay, I don't need compatibility this time around. I just want need performance better than what a telnet to the ROACH can give me. Future revisions of this project will be on a custom board anyways Thanks for all of your (collective) help. Problem solved... for now ;-) --Ryan On
