morning everyone!
62
15:42
se6astian
hello!
63
15:43
se6astian
great, news we got another high level developer interested
64
15:45
Bertl
so who is it and what does (s)he develop?
65
15:46
se6astian
check your emails :)
66

FergusL
awesome news on the mailing list
67
15:49
se6astian
time too cook :)

Seems like we finally found someone to properly review the PCB layout
80
18:06
se6astian
...one day after we ordered ;)
81
18:22
Bertl
well ... so far common places and hand waving
82
18:23
Bertl
but yes, input is always appreciated
83

I've been hearing recommendations for kicad
84
18:33
Bertl
yeah, I would have preferred kicad, it has become quite useable
85
18:33
Bertl
but the problem is, it is still lacking a lot of features and it would have taken me a lot longer to get there with kicad
86
18:34
Bertl
we will probably convert the eagle files to kicad later
87
18:37
dmj_nova1
yeah, I figure that's a good idea long term
88
18:40
Bertl
one 'problem' with kicad (might be considered a feature :) is that it separates schematic parts from footprints
89
18:40
Bertl
another is that foward/backward annotation is quite cumbersome
90
18:41
Bertl
but as cern has a project running to make kikad a replacement for altium, I'm sure this will improve over time
91
18:41
Bertl
*kicad even

se6astian: btw, did you realize that lu_zero payed a visit to the channel?
94
18:43
Bertl
and showed some interest to help us with the userspace streaming once we are there

ah, no I didnt notice that

se6astian
lu_zero, do we have any other info on him as well?
100
19:02
se6astian
What do you think of Gregs feedback/questions: according to the FMC specification, CLK are inputs only, they cannot
101
19:02
se6astian
feed the clock. Probably ZYNQ devkit can do this but it may not work
102
19:02
se6astian
with other FMC carriers.
103
19:02
se6astian
- in the case of the FPGA, if you want to use hardware serdes, you
104
19:02
se6astian
must use local clock inputs. Using general CLK that is often routed to
105
19:02
se6astian
another bank may be wrong idea. Did you try to synthesize the FPGA
106
19:02
se6astian
core with ioserdes? I would suggest using LA00/01 and LA17/18 as clock
107
19:02
se6astian
inputs because they should to the local clk inputs. But I didn't
108
19:02
se6astian
analyze your devkit, we had troubles in the case of fast ADCs with
109
19:02
se6astian
serial outputs that somebody routed to global clk inputs.

I've replied to the mail :)

112
19:22
se6astian
perfect!
113
19:22
se6astian
lu-zero, interesting
114
19:23
se6astian
userspace-streaming would that be the Ethernet video stream software for example?
115
19:23
Bertl
yeah, jucar1 introduced him to this project

Bertl
as he has some experience with ffmpeg, codecs and kernel drivers, I think that might be valuable help
118
19:24
se6astian
wonderful!
