| 09:42 | Bertl | morning folks!
|
| 09:43 | John_K | morning~
|
| 09:43 | Bertl | hey John_K! how's going?
|
| 09:43 | John_K | Bertl: I have the sensor working I think
|
| 09:43 | Bertl | excellent!
|
| 09:44 | John_K | trying to get an image out with cmv_snap3 but it says waiting on sequencer
|
| 09:44 | John_K | did cmv_init, cmv_train3 and then cmv_snap3
|
| 09:44 | John_K | am I missing a step?
|
| 09:45 | Bertl | the systemd script is active/successful?
|
| 09:46 | Bertl | or better, did you somehow run kick.sh (kick_manual.sh)?
|
| 09:46 | John_K | I did not, but I can now
|
| 09:46 | John_K | getting a ton of spam from gpio_jtag_pcie
|
| 09:47 | John_K | woohoo
|
| 09:47 | John_K | data
|
| 09:48 | Bertl | ah, yes, the gpio_jtag_pcie needs to be replaced
|
| 09:48 | Bertl | you want to call pic_jtag_pcie there
|
| 09:48 | Bertl | (which is used for HDMI out, so no problem right now)
|
| 09:49 | John_K | the blue LED is flickering fast, can I presume that's the rate at which it's displaying over HDMI?
|
| 09:51 | Bertl | yep, run cmv_perf3 for details
|
| 09:51 | Bertl | well, actually it is the rate at which the sensor captures
|
| 09:51 | Bertl | the HDMI rate is currently fixed to 60 FPS
|
| 09:51 | John_K | aha
|
| 09:52 | Bertl | you can stop the live output with: fil_reg 15 0
|
| 09:52 | Bertl | snap will still take a picture if called
|
| 09:52 | John_K | that will be very handy
|
| 09:53 | John_K | trying to load images
|
| 09:54 | Bertl | you can turn live view on again with: fil_reg 15 0x01000100
|
| 10:00 | tezburma | left the channel |
| 10:00 | John_K | does this look like a decent imagemagik commandline to take 12-bit grayscale to png?
|
| 10:00 | John_K | cat test.raw12 | convert \( -size 4096x3072 -depth 12 gray:- \) test4.png
|
| 10:05 | Bertl | yep, you can directly pipe it into display for testing
|
| 10:05 | Bertl | ssh root@beta "./cmv_snap3 -2 -e 20ms" | display -size 4096x3072 -depth 12 gray:-
|
| 10:13 | John_K | hrm, so I shut down the camera and rebooted and now cmv_init fails
|
| 10:13 | John_K | aha
|
| 10:15 | Bertl | best to get the kick.sh active
|
| 10:16 | Bertl | or turn the systemd service off an run it manually
|
| 10:16 | John_K | there appears to be a cold solder joint somewhere still
|
| 10:16 | John_K | yeah I'm just doing kick_manual right now
|
| 10:16 | Bertl | happens sometimes, best check the connectors (most likely there)
|
| 10:17 | Bertl | IIRC, I mentioned the pin test trick with the needle, yes?
|
| 10:17 | John_K | yes
|
| 10:17 | John_K | was going to ask you about test fixtures / devices as well
|
| 10:18 | John_K | since I'll hopefully be making around 150 of these, would be good to have an automated tester for that - I was thinking another microZed
|
| 10:18 | Bertl | yeah, we are working on something like that :)
|
| 10:20 | John_K | I'd be happy to help design some parts
|
| 10:20 | John_K | I wanted to ask about PMICs as well
|
| 10:21 | John_K | if you had looked into any
|
| 10:21 | Bertl | you mean for a higher input range?
|
| 10:21 | John_K | mostly to replace all of the LDOs with a single IC
|
| 10:21 | John_K | with a single I2C control
|
| 10:22 | Bertl | ah, yes, this is what we plan for the next power board
|
| 10:22 | John_K | have you evaluated / considered candidate PMICs yet?
|
| 10:22 | Bertl | (where voltages can be controlled)
|
| 10:22 | John_K | right
|
| 10:23 | John_K | I guess that's far enough in the future though
|
| 10:23 | Bertl | we have been thinking about a microchip solution for power management
|
| 10:25 | Bertl | a single chip is unlikely to handle all the power rails
|
| 10:25 | John_K | cellphone PMICs likely can
|
| 10:26 | John_K | although they're generally hard to find outside of aliexpress though
|
| 10:26 | Bertl | do you have anything specific in mind which is readily available, well documented and relatively cheap?
|
| 10:26 | Bertl | s/relatively cheap/reasonably priced/ :)
|
| 10:26 | John_K | not well documented :\
|
| 10:26 | John_K | qualcomm PMIC8916 is about $5/per from aliexpress
|
| 10:27 | John_K | and has something like 30 LDOs
|
| 10:27 | John_K | and an I2C interface
|
| 10:27 | John_K | unsure of amperages per LDO though, likely <1a
|
| 10:28 | John_K | alright, I need a better test image setup
|
| 10:28 | Bertl | between 50 and 1200mA it seems
|
| 10:28 | Bertl | (according to the datasheet)
|
| 10:28 | John_K | I appear to be able to under or overexpose it quite handily
|
| 10:29 | John_K | oh hey, the datasheet is available now
|
| 10:36 | John_K | yeah even a newer PMIC from them still tops out at 1.2A for LDO
|
| 10:42 | John_K | @Bertl https://kelley.ca/temp/test8-adjusted.png
|
| 10:42 | John_K | seems like there is some wrapping issue, but otherwise things look ok
|
| 10:43 | John_K | focus is way off, but that's my fault
|
| 10:49 | Bertl | wrapping means you started some scripts more than once
|
| 10:49 | Bertl | without stopping acquisition
|
| 10:49 | Bertl | (it's a software bug)
|
| 10:50 | Bertl | but image looks nice
|
| 10:50 | Bertl | i.e. there is data in the capture FIFOs which is not accounted for
|
| 10:50 | Bertl | because the firmware got replaced while the FIFOs where active
|
| 10:51 | Bertl | if you reboot the zynq and run the kick.sh only once, everything should be aligned properly
|
| 11:04 | John_K | ahh
|
| 11:04 | John_K | ok I'm off to bed
|
| 11:05 | John_K | thanks for all your help getting this far!
|
| 11:06 | John_K | is this the first time someone has assembled an Axiom Beta outside of Apertus?
|
| 11:09 | Bertl | probably
|
| 11:09 | Bertl | have a good night then
