[David MacMahon]

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 exit_fail() as it appears on 
GitHub:

def exit_fail():
print 'FAILURE DETECTED. Log entries:\n',lh.printMessages()
try:
fpga.stop()
except: pass
raise
exit()

I think this try/except block (with "pass" in the except part) followed by 
"raise" is completely superfluous.  I think it means try to do something and if 
an exception is raised while trying, ignore it but then re-raise it, which 
seems exactly the same as not having the try/except block there at all!  Not to 
mention that the exit() call will never be reached.  I’m also not a fan of 
functions that can only be called while an exception is being handled 
(otherwise the no-arg form of "raise" will bomb out I think).

It would probably be preferable to pass the original exception to exit_fail() 
as an argument so that the original exception can be re-raised.  I can make 
that change when I get back to Berkeley next week (unless someone beats me to 
it).

Sorry for veering so far off topic,
Dave

Re: [casper] Programming a ROACH2

[Jason Manley]

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.

Editorial comments on error handling in tut3.py aside, I think the fact that 
"FAILURE DETECTED" follows "Connecting to server…" on the same line (i.e. no 
newline character inbetween) means that something went wrong when constructing 
the FpgaClient object which connects to TCP port 7147 of the ROACH2 with IP 
address 192.168.33.7.  This is expecting the ROACH2 to have a tcpborphserver 
process listening on that port.

What happens when you run:

telnet 198.168.33.7 7147

Re: [casper] Programming a ROACH2

[Marc Welz]

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

Re: [casper] Programming a ROACH2

[Heystek Grobler]

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))

Re: [casper] Programming a ROACH2

[James Smith]

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 been updated for the recent
CASPER workshop. Can someone comment on this?

It might be an interesting exercise to try and use the model files to
compile for ROACH2 then to write your own script, using this one as a
guide. You'd learn a lot about how things work in the process. Not a quick
fix to your problem, I'll admit, but it'll be an education.

Regards,
James

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.

Re: [casper] Programming a ROACH2

[Heystek Grobler]

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 192.168.33.7 on port
7147...  FAILURE DETECTED. Log entries:
None
Traceback (most recent call last):
  File "./tut3.py", line 141, in 
exit_fail()
  File "./tut3.py", line 21, in exit_fail
fpga.stop()
NameError: global name 'fpga' is not defined


Any ideas on how to solve this?

Thank you

Heystek

 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!!
