[casper] Configuring ROACH2 to work autonomously
Follow this method to store boffiles in the on-board flash. One can transfer the files by mounting an NFS file system or download the file from a web serve. NFS (Requires a NFS server): 1. Use minicom or another terminal emulator to access the console via USB. (ttyUSB2) 2. Reboot the machine and let it soloboot or just make sure the ROACH2 has booted from flash. 3. Login with username: root, leave the password blank 4. Mount the NFS, type at the prompt: mount -t nfs -o nolock server_IP:nfs_path /mnt 5. Copy the boffiles across. Boffiles are stored in nfs_path/boffiles. It is also better to gzip them as well, speeds up flash reads and you can store more. Copy and gzip in one example: cat /mnt/boffiles/example.bof | gzip -c - /usr/bof/example.bof.gz HTTP: 1. Use minicom or another terminal emulator to access the console via USB. (ttyUSB2) 2. Reboot the machine and let it soloboot or just make sure the ROACH2 has booted from flash. 3. Login with username: root, leave the password blank 4. cd /usr/bof 5. Server the boffile on a web server, it is better to gzip the boffiles, speeds up the transfer and you can store more. webfsd is easy to use: a) Enter the directory containing the boffiles b) webfsd -p 8080 -r . (use any free port over 1024) 6. wget http:/server_ip:port/file How to configure the ROACH2 to load a boffile at startup: 1. Use minicom or another terminal emulator to access the console via USB. (ttyUSB2) 2. Reboot the machine and let it soloboot or just make sure the ROACH2 has booted from flash. 3. Login with username: root, leave the password blank 4. cd /etc 5. vi tcpborphserver3.init 6. At the end add: ?progdev boffile (don't include a path) 7. Any other katcp commands can be added. Any questions, please don't hesitate to ask. Regards Alec PS. Please update your kernel and romfs to the latest version, I will send an email shortly with instructions.
[casper] Updating romfs, new tcpborphserver3 and sensors
Marc has modified tcpborphserver3 to work with normal 8 bit writes now. Please get the latest one here: https://github.com/ska-sa/roach2_nfs_uboot (the files are in boot). If you are running a NFS just copy the file to nfs_path/usr/local/sbin The latest romfs includes the new tcpborphserver3. To update: ROACH2 Test machine set-up instructions: https://docs.google.com/a/ska.ac.za/document/d/1tqw4C6uZ6EULl1OykTFL_vQTnK52UBr0aYqTg44E5wg/edit ) 1. Set up a tftp and dhcp server (see the tftp section in the test machine setup instructions). 2. Create a symlink or rename the romfs image to romfs e.g. ln -s roach2-root-2012-10-18.romfs romfs in the tftp directory. 3. At the uboot prompt type: run tftproot 4. This takes a long time! About 5 minutes. 5. Using a terminal emulator like minicom access the console (minicom ttyUSB2) 6. Login using root (password is blank) 7. rm /usr/.keep 8. reboot -f To measure temperatures, voltages and currents: All sensors are available using kcp commands. You can telnet to the board to run kcp commands (telnet board_ip 7147) or if you have access to the console you can run the commands using the program kcpcmd (kcpcmd sensor-list note that there is no ?) ?sensor-list - lists all the sensors ?sensor-value - lists all the current values ?sensor-sampling sensor_name event - this will give updates when the sensor changes. If anything is unclear please don't hesitate to ask. Regards Alec PS. For rev1 boards please make the following changes to /etc/tcpborphserver3.init (after removing .keep and rebooting). Note that on rev1 3v3aux is actually 12v and 12v and 5vaux will read 0: #3v3 sense resistor: 0.002 ohm, gain resistor: 200 ohm ?sensor-limit raw.current.3v3 mult 998 ?sensor-limit raw.current.3v3 div 1000 #2v5 sense resistor: 0.005 ohm, gain resistor: 499 ohm ?sensor-limit raw.current.2v5 mult 993 ?sensor-limit raw.current.2v5 div 1000 #1v8 sense resistor: 0.002 ohm, gain resistor: 200 ohm ?sensor-limit raw.current.1v8 mult 998 ?sensor-limit raw.current.1v8 div 1000 #1v5 sense resistor: 0.001 ohm, gain resistor: 100 ohm ?sensor-limit raw.current.1v5 mult 999 ?sensor-limit raw.current.1v5 div 1000 #1v sense resistor: 0.00025 ohm, gain resistor: 100 ohm ?sensor-limit raw.current.1v mult 399 ?sensor-limit raw.current.1v div 100 #12v sense resistor: 0.005 ohm ?sensor-limit raw.current.12v mult 100 ?sensor-limit raw.current.12v div 500 #5v sense resistor: 0.002 ohm ?sensor-limit raw.current.5v mult 100 ?sensor-limit raw.current.5v div 200 #12v voltage divider (on rev1 boards the 12v is measured on the 3v3aux line) ?sensor-limit raw.voltage.3v3aux mult 29600 ?sensor-limit raw.voltage.3v3aux div 1

Hi, Alec (and Marc), Thanks for all this! On Dec 20, 2012, at 7:46 AM, Alec Rust wrote: Marc has modified tcpborphserver3 to work with normal 8 bit writes now. Please get the latest one here: https://github.com/ska-sa/roach2_nfs_uboot (the files are in boot). If you are running a NFS just copy the file to nfs_path/usr/local/sbin For those of us who like to build from source, have all the tcpborphserver3 updates been pushed to the source code repository (git://github.com/ska-sa/katcp_devel.git)? PS. For rev1 boards please make the following changes to /etc/tcpborphserver3.init (after removing .keep and rebooting). Note that on rev1 3v3aux is actually 12v and 12v and 5vaux will read 0: Is there any setup here that could be used with both rev1 and rev2 roach2s? I have a netboot filesystem that I would like to use for both rev1 and rev2 boards. Can I completely disable the 3.3vaux, 12v, and 5vaux limits? What happens if these limits are exceeded? Thanks, Dave
[casper] tcpborhserver architecture
It's clear that tcpborphserver is going to become the de facto method of interacting with user gateware on ROACH2 boards as well as an important method for interacting with the ROACH2 board itself. This is great for programming and configuring designs across multiple ROACH2 boards. It's so great that users will want to start adding their own commands to the tcpborphserver program. Instead of having users rebuilding the tcpborphserver program every time they add or change a custom command, I would like to propose a plug-in architecture for tcpborphserver. This would allow users to create shared libraries that the tcpborphserver executable could load *at runtime* to register new commands with tcpborphserver. This keeps the tcpborphserver program lean and focused on the core functionality, yet allows different sites to provide and use their own site-specific customizations to tcpborphserver3. Unfortunately I don't have the mandate to do this myself, but I still wanted to put this idea out there for consideration. Thanks, Dave Here is a simplified overview for a plugin named garbonzo: 1) Create a shared library named garbonzo.so. The tcpborphsever executable would load this (when requested) using dlopen(). 2) Shared library must have function named Init_garbonzo that tcpborhserver will locate via dlsym() and then call. This init function will register new command-name-to-funtion-pointer mapping(s) with tcpborhserver. 3) Now the new commands are available!
[casper] KATADC attenuators
I have two KATADCs, one each in ZDOC0 of two ROACH-1 boards (named roach1 and roach2). It appears that the attenuator for input 0 of the KATADC in roach2 is at 0 dB for whatever attenuation setting command is sent to it. The other three inputs respond as I expect. I assume that this is some kind of hardware failure but I thought I'd better check if there was some jumper setting or control bit that I don't know about. With thanks and best regards, Tom
Re: [casper] KATADC attenuators (Tom Kuiper)
Tom, I suggest that you swap the KATADC boards between roach1 and roach2. Does the problem stay with roach2 or does it move with the KATADC board? Are you running exactly the same .bof file on both ROACHes? --Larry -- === Larry R.

Re: [casper] spectrometer 1Ghz
I'll just chime in that I've seen this error before, which I solved by switching to a different version of the library. I can't help with this one, just wanted to say it's probably not operator error. --Ryan On 12/20/2012 01:24 PM, katherine viviana cortes urbina wrote: Hi Mark, Today I change the fft in my design , I also open up the parameter boxes of both and make sure that the parameters are the same, I delete the old and replace it with the new, but I have the same error, Detected Linux OS # ## System Update ## # Error using == gen_xps_files at 199 Error due to multiple causes.

Re: [casper] spectrometer 1Ghz
Hi Katty, Are you using the current version of casper-astro/mlib_devel.git libraryhttps://github.com/casper-astro/mlib_devel? If not, what version are you using? Would you mind doing a screen capture of your FFT parameter box (all tabs)? We'll check on it. If this is a bug in our current library then we definitely need to fix it as soon as possible...

I'm pretty sure that I know how that would turn out. Unfortunately, I'm at home in West LA, 30 min with no traffic. I can ask Dong to do it but it's a hassle so I'll wait to make sure that I haven't missed some minor point. Are you running exactly the same .bof file on both ROACHes? Yes. Tom
