Afternoon Guy
Regarding question 3... if you're running tcpborphserver3 you can use the
upload_bof method in the FpgaClient class in corr to upload a bof file to
your ROACH. I just checked and it took about 12s to copy a boffile using
this. Once it's uploaded, though, it will skip uploading it unless you
force it to do so. Use progdev to program the device as usual.
Regards
Paul

Hello,
we received 2 roach2 boards from digicom (20th dec 2012).we managed to
configure our minicom with centos6.2 final, and tty usb2.
I've several questions about the advised version for the uboot and the
tcborphserver3
u-boot versionof my boards:
u-boot 2011.06-rc2-00000-gd422dc0-dirty(Nov 8 2012 - :16:04:14)
#SN : Roach2.2 batch = D#6#10
#kernel : Linux roach 02 06 0A 3.4.0 - rc3+
Tcpborphserver3
1/
a- how can I find the version of my romfs and also how can I find the
version of my Tcpborphserver3
b- which version for the uboot and the tcborphserver3 should I use, should
I keep the current version above ?
where is it located?
2/ I heard that the configuration with the SD card is not yet working ?
is it still the case ?
3/I want to load my boffiles, can I use ssh ? or should Iuse the telnet
to tranfer my files ?
How should I do If I want to keep my boffiles alive? I used to store them
on the SD card, even when shutting down my roach board. Do I need to
re-load or to copy my boffiles after switching on my roach2 boards?
I read somewhere that it could be possible to upload from the python
?(I've never done it)
How long does it take to the boffile to be copied ? before launching the
fpgaprogdev() ?
Thank you for your help,

Hello
1/
a- how can I find the version of my romfs and also how can I find the
version of my Tcpborphserver3
if you telnet to port 7147, there should be a version string
for tcpborphserver3. The romfs contains a timestamp in its filesystem
label, but since it such a small system, you can pretty much use the
tcpborphserver3 version string as a proxy for it
b- which version for the uboot and the tcborphserver3 should I use, should I
keep the current version above ?
where is it located?
The source is in git at github.com/ska-sa
2/ I heard that the configuration with the SD card is not yet working ? is
it still the case ?
Yes. A roach2 has sufficient onboard flash to keep a number of
(optionally compressed) bof files there
without having to use external storage, so we not allocated anybody to
work on the MMC logic. Also note that MMC cards can be "interesting", see
http://www.bunniestudios.com/blog/?p=2297
So we recommend you soloboot, ie boot off the onboard flash.
3/I want to load my boffiles, can I use ssh ? or should Iuse the telnet to
tranfer my files ?
How should I do If I want to keep my boffiles alive? I used to store them on
the SD card, even when shutting down my roach board. Do I need to re-load or
to copy my boffiles after switching on my roach2 boards?
The content of /usr on the onboard flash is preserved, so the bof files in
/usr/bof are retained.
I read somewhere that it could be possible to upload from the python ?(I've
never done it)
How long does it take to the boffile to be copied ? before launching the
fpgaprogdev() ?
I think Paul answered that (but note that you will need a pretty recent version
of tcpborphserver3 to use the uploadbof request).
If you are concerned about speed, you can transfer a bof file
beforehand (say using wget or ftpget or an nfs mountpoint) - then
the progdev is pretty quick, and you can then even arrange that the
file is programmed at startup (by adding a progdev command to
etc/tcpborphserver3.init)

marc
