22:06 | Bertl | so, if you installed a tftp server as well, you should now see requests for /ZED/u-boot.scr
| |
22:06 | Bertl | (in the logs)
| |
22:07 | Bertl | you need to create the ZED directory in you /var/lib/tftp directory (or wherever tftp looks for on ubuntu) and copy the files from my TFTP/ZED directory there
| |
22:09 | Bertl | note that you then can create symbolic links (ln -s <from> <to>) from the ZedBoard_OOB_Design directory to the ZED directory (e.g. for system.bin, zImage and devicetree_ramdisk.dtb)
| |
22:20 | Bertl | ah, great, ISE can be used to show (at least the xilinx) .ngc
| |
22:25 | Bertl | off to bed now ... good luck!

10:33 | Bertl | dmj_nova: did you manage to get the tftp working yesterday?
| |
10:38 | s3bastian | hello!
| |
10:41 | Bertl | hey, how's going?

16:35 | Bertl | back ...
| |
17:37 | s3bastian | dmj_nova, let me know when you are here
| |
18:08 | dmj_nova | s3bastian: I'm around
| |
18:11 | Bertl | yay!
| |
18:16 | s3bastian | hurray
| |
18:16 | s3bastian | did you reach andon?
| |
19:08 | dmj_nova | s3bastian: yes I did
| |
19:13 | dmj_nova | s3bastian: just sent you the quote
| |
19:15 | Bertl | great news!
| |
19:21 | Bertl | btw, I updated the pmod_debug module, it should now have reached the 'final' v1.0 state :)
| |
19:23 | Bertl | dmj_nova: how good are you with SMD soldering?
| |
19:24 | s3bastian | dmj_nova, many thanks, great
| |
19:24 | dmj_nova | Bertl: I have no idea since I've never done it
| |
19:24 | dmj_nova | always ended up soldering through-hole
| |
19:24 | dmj_nova | even on my parent's TV :P
| |
19:25 | Bertl | okay :)
| |
19:25 | dmj_nova | but I'm happy to try and learn :)
| |
19:28 | [1]s3bastian | joined the channel | |
19:30 | Bertl | yeah, well, I was considering sending some of the PCBs directly to you, but I guess this wouldn't be the best project to start with
| |
19:30 | s3bastian | left the channel | |
19:30 | [1]s3bastian | changed nick to: s3bastian
| |
19:31 | Bertl | especially as I can easily reflow solder the LEDs here
| |
19:31 | Bertl | OTOH, if you really want to try, you could probably do it on a hot plate as well
| |
19:33 | s3bastian | Bertl, do you have any good tricks for smd part placing? I remember a friend of mine modded his vacuum cleaner so he could hold smd parts with a very spiky suction tip and on a button press he could open an outlet on the tube to release the parts
| |
19:33 | Bertl | sounds interesting, but you can get so called 'vacuum pens' for a few bucks nowadays
| |
19:34 | s3bastian | I guess that would have saved him a lot of trouble
| |
19:35 | Bertl | which help for larger parts, but everything below 0805 is IMHO easier placed with a good forceps
| |
19:37 | Bertl | placement doesn't matter that much actually for reflow
| |
19:38 | Bertl | you just have to make sure that the part is placed in the middle, the hot solder will re-align it to the pads (if they are done properly)
| |
19:39 | Bertl | https://www.youtube.com/watch?v=3drirgNktQg
| |
19:40 | Bertl | (nice video to show how it works, and fails with the wrong pads :)
| |
19:43 | Bertl | https://www.youtube.com/watch?v=1xNSMTWhEvg
| |
19:57 | Bertl | hmm, I just realized that we probably want to make the VREF and VREF_ADC for the CMV12k adjustable, no?
| |
19:58 | Bertl | so we probably should consider a dual port DAC via I2C for that (i2c is available via FMC, so no big deal)
| |
20:05 | Bertl | (they are marked as test pins, so I'm not sure, but the reference design has them connected to DACs)
| |
20:24 | s3bastian | interesting videos
| |
20:24 | s3bastian | are there any pick and place DIY robots in the works btw?
| |
20:24 | s3bastian | like a 3d printer cnc with a tweezer head?
| |
20:26 | Bertl | well, it's a little tricky to extract them from reels (and you probably don't want to use the non-reeled versions for automated placement)
| |
20:30 | s3bastian | and I guess the next problem is that you would need many reel extractors in case you build something that does that
| |
20:31 | s3bastian | what if the parts would come without reel and just be piled up next to the pcb
| |
20:31 | s3bastian | the pick and place head would need to be able to rotate the parts
| |
20:31 | s3bastian | and have a camera to find and identify them
| |
20:31 | s3bastian | too complex or DIY I figure
| |
20:33 | s3bastian | dmj_nova, we decided to order the sockets in the USA
| |
20:33 | s3bastian | would it be OK if you ordered them and forwarded the package to us
| |
20:33 | s3bastian | we will pay for everything of course :)
| |
20:57 | dmj_nova | s3bastian: You know what needs ordering yet?
| |
20:57 | s3bastian | yes, 5x thru-hole with window
| |
21:03 | dmj_nova | wow, that is quite a big pricing difference
| |
21:07 | s3bastian | indeed
| |
21:07 | s3bastian | even with import duties and double shipping
| |
21:08 | dmj_nova | well, as long as the import duties and double shipping are less than $200 that is
|
