dmj_nova1
it definitely has the boot.bin from your site
23:06
Bertl
is there a BOOT.BIN and a boot.bin?
23:06
dmj_nova1
I just pasted it there again
23:06
dmj_nova1
nope
23:07
dmj_nova1
there was
23:08
dmj_nova1
a BOOT.BIN but it got written over by the boot.bin
23:08
dmj_nova1
days ago
23:08
Bertl
okay, what does (on the uboot prompt) 'printenv modeboot' give?
23:10
dmj_nova1
modeboot= run sdboot
23:11
Bertl
that looks good, and 'printenv bootcmd' ?
23:12
dmj_nova1
bootcmd=run modeboot
23:12
Bertl
that is wrong, hmm
23:13
Bertl
okay, when uboot first starts, what date(s) does it show?
23:16
dmj_nova1
Jun 23013
23:17
Bertl
okay, that looks good, check does 'printenv tftpboot' give you anything?
23:18
Bertl
(assuming that this is Jun 23 2013 - 19:36:00 :)
23:19
dmj_nova1
tftpboot=echo Scripted Boot via TFTP...;fpga info 0;echo Requesting Boot Script via TFTP...;bootp 0xF00000;echo Executing Boot Script...;source 0xF00000
23:19
Bertl
that's fine, so it seems that just your modeboot wasn't updated
23:24
dmj_nova1
how do I update the modeboot?
23:26
Bertl
yeah, checking ... the problem is, the digilent u-boot (the one we are using because it has way better network support) doesn't have the saveenv command
23:43
Bertl
try 'env default -f'
23:45
Bertl
btw, I updated the boot.bin just now so that it has the verbose/long help enabled
23:50
Bertl
does that work?
23:51
dmj_nova1
no
23:51
Bertl
hmm, thought so, we probably need the saveenv active
23:52
Bertl
give me a second to check if I can make it work
00:04
Bertl
dmj_nova1: okay, grab the boot.bin again, I added the saveenv stuff
00:04
Bertl
then interrupt the autoboot and do
00:04
Bertl
env default -f
00:04
Bertl
saveenv
00:05
Bertl
reset
00:10
dmj_nova1
didn't change anything
00:20
Bertl
strange, worked here (with the new boot.bin)
00:21
Bertl
do you have the transcript?
00:21
Bertl
(i.e. can you copy/paste it somewhere?)
00:23
dmj_nova1
http://paste.ubuntu.com/5863240
00:26
dmj_nova1
Bertl: so it seems to be loading different addresses
00:26
dmj_nova1
not sure if that's significant
00:26
dmj_nova1
0x0 in my case and 0xf00000 in yours
00:28
Bertl
ah, you are interrupting the autoboot
00:28
Bertl
just let it count down to zero
00:29
Bertl
(it's all automated :)
00:36
dmj_nova1
hmm...getting further but now I get some file not founds
00:36
dmj_nova1
So in the tftp directory...
00:37
Bertl
did you create the symbolic links?
00:38
Bertl
for example (in the ZED directory)
00:38
dmj_nova1
there should be a folder called 'ZED' with 'u-boot', 'u-boot.bin', 'u-boot.scr', and 'uboot.script' inside, yes?
00:38
Bertl
ln -s ZedBoard_OOB_Design/ramdisk8M.image.gz ramdisk.image.gz
00:38
Bertl
ln -s ZedBoard_OOB_Design/zImage zImage
00:39
Bertl
ln -s ZedBoard_OOB_Design/system.bin system.bin
00:39
Bertl
ln -s ZedBoard_OOB_Design/devicetree_ramdisk.dtb devicetree_ramdisk.dtb
00:39
Bertl
this is to simplify exchaning certain components later
00:40
Bertl
e.g. I have a BERTL folder, which has my files, and I just change the symlink of the system.bin for example
00:44
dmj_nova1
http://paste.ubuntu.com/5863290
00:44
Bertl
\o/
00:45
Bertl
you probably want to adjust the static IP and/or use DHCP for that in the linux runlevel scripts
00:45
Bertl
but that is something you probably can do on your own, yes?
00:46
dmj_nova1
should be able to
00:46
dmj_nova1
thanks for your help getting it booted
00:46
Bertl
you're welcome!
00:47
Bertl
please add the env reset to the wiki
00:47
Bertl
i.e. the env default -f, saveenv part

s3bastian
indeed
12:31
s3bastian
it was a long time ago since I last used IRC regularly
12:31
s3bastian
in the good old days of collaborative game development ;)
12:31
s3bastian
must be almost 10 years ago now... crazy how time flies
12:31
s3bastian
so Bertl got us to rediscover the beauties of IRC
12:34
Bertl
morning everyone!
12:35
Bertl
hello FergusL!
12:35
FergusL
haha; great !
12:36
FergusL
are you on the forums Bertl ? if so, what name ? (just to match nicknames together)
12:39
Bertl
my name is Herbert, but usually folks call me Bertl :)
12:39
s3bastian
Bertl joined just recently - no forum account as far as I know
12:40
Bertl
didn't even know there was a forum ...
12:44
s3bastian
Bertl, I have to leave in 10 minutes, but before I do I have some questions after starting to get to know your SFE PCB 0.7
12:45
s3bastian
whats the difference between the layers: top and topsignal ?
12:45
Bertl
4-layer top, top-signal, bottom-signal, and bottom
12:46
Bertl
top has twice as much copper per square inch as top-signal
12:48
s3bastian
I see
12:54
Bertl
FergusL: so, what are you working on?
12:56
s3bastian
Bertl, another question, in my expresspcb layout I grouped LVDS pairs together so they can "couple" to each other, in your design space is rather evenly distributed between pairs and the paired lines, is the coupling for such short lines not that relevant anyway?
12:57
s3bastian
actually I now see that you couple them on top of each other
12:57
s3bastian
genius!
12:57
Bertl
hehe :)
12:57
Bertl
that is called broad-side matching
12:58
s3bastian
yes I remember you explained the difference so I get to actually see it!
12:58
s3bastian
nice
12:59
Bertl
there are a few other tricks/hacks to make it work with just 4 layers
13:02
Bertl
there are some ground and power planes on the signal layers for shielding/power distribution (you normally avoid that mess if you have more layers available)
13:04
s3bastian
I see, OK gota leave for an appointment
13:04
s3bastian
see you
13:06
Bertl
cya

FergusL
Bertl: I'm not working on anything specific regarding Axiom
13:10
FergusL
I do some electronics, nothing like multiple layers pcbs but I can figure out layouts and understand conversations about it :)
13:12
Bertl
well, if you want to take a look, the eagle files are here: http://vserver.13thfloor.at/Stuff/AXIOM/qad-center-v0.7.sch and http://vserver.13thfloor.at/Stuff/AXIOM/qad-center-v0.7.brd
13:12
Bertl
(note: still work in progress)
13:13
FergusL
thanks !
13:15
Bertl
you're welcome! feedback is always appreciated!

Bertl: what version of Eagle should I use to open these ?
17:21

left the channel
17:23
Bertl
FergusL: 6.4 should be fine, I'm using 6.4.4
17:23
FergusL
File > Open > Schematic or Board, pointing to the files, doesn't seem to work, it says "invalid data". let me dig into this, I mist confess I never used Eagle
17:27
Bertl
s3bastian: ping?

I am here
17:44
s3bastian
now :)
17:44
Bertl
perfect! so what do you think of the adapter layout/design so far?
17:47
s3bastian
looks very good and tidy!
17:48
Bertl
FergusL: hmm, that's basically what I (and probably s3bastian) do ...
17:48
Bertl
could you paste me the first and the last few lines of the files you downloaded?
17:48
Bertl
(or do an md5/sha sum)
17:49
FergusL
let's go for an md5, can you paste yours ?
17:49
Bertl
sure, sec
17:50
FergusL
I'm suspecting wrong copying or dl, though I grabbed it with wget
17:51
Bertl
http://vserver.13thfloor.at/Stuff/AXIOM/md5.info
17:51
Bertl
wget should be fine
17:51
Bertl
s3bastian: you are opening the files with eagle, yes? what version do you use?
17:52
Bertl
FergusL: note that between 5.x and 6.x they changed the fileformat, 6.x uses xml (5.x was some proprietary binary thingy)
17:53
FergusL
haaa then it should be this, I have version 5 something
17:53
Bertl
just grab the 6.x from cadsoft (linux, mac, win)
17:53
FergusL
'k
17:54
Bertl
you can go for the 6.4.4 beta version if you like, it is quite stable
18:01
FergusL
Bertl: nice, much better now :)
18:01
Bertl
hehe
18:02
FergusL
absolutely beautiful haha
18:07
s3bastian
I use eagle 6.4.0
18:07
s3bastian
worked flawlessly
18:08
FergusL
yes, perfect with 6.4.0
18:20
FergusL
where are all the LAxx signals going ? I take it they are lvds out from the sensor. maybe directly to the zed ?
18:20
Bertl
yes, they go from the CMV12k to the FMC connector at the bottom
18:20
Bertl
which direcly plugs into the zedboard
18:22
FergusL
ha I see
18:22
FergusL
lots of pins ! hehe
18:23
Bertl
yeah, I added a shield plane on the Bottom-Signal layer to shield that one
18:23
Bertl
(although there are not many signals in the vicinity with this layout)
18:25
FergusL
that's actual electrical shielding, like, to avoid noise ?
18:27
Bertl
yes, we are transmitting LVDS signals at 300MHz (not so much but enough)
18:27
Bertl
so we want to make sure that we do not mess up our data
18:29
FergusL
indeed yes !
18:33
FergusL
is this channel considered public ? from the website it is
18:33
Bertl
yes, I'd say so, at least I consider it public :)
18:33
FergusL
but are those schematics public too then ?
18:34
Bertl
yes, they are
18:39
s3bastian
They are on our GitHub account already
