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

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
