morning folk :)
08:39
jarhab[m]
how do you build u-boot and how do you assemble it into the image?

morning folks! morning jarhab[m]!
08:50
Bertl
u-boot needs to be combined with the FSBL into BOOT.bin
08:51
Bertl
https://lab.apertus.org/T37
09:00
jarhab[m]
and where to put the BOOT.bin? into the first partition? at a specific adress?
09:01
jarhab[m]
and in the link you send, there were no specific build instructions :(
09:03
Bertl
the Axiom Beta is configured to boot from SD card, and the BOOT.bin goes to the first partition
09:03
Bertl
but you can also boot it from SPI if configured properly
09:10
jarhab[m]
ok
09:10
jarhab[m]
do you know what the last unformattedt partition in http://vserver.13thfloor.at/Stuff/AXIOM/BETA/build_image.sh is for?
09:11
Bertl
you mean partition 3, yes?
09:13
jarhab[m]
yeah
09:13
jarhab[m]
and the 0 size partition 4
09:14
Bertl
partition 3 is for data, basically contains overlay images, source code for all tools, bitstreams etc
09:14
Bertl
partition 4 is unused, it is just there because the DOS partition table has 4 partitions
09:14
jarhab[m]
ah ok
09:15
jarhab[m]
why do you seperate the data from the base os?
09:15
jarhab[m]
wouldnt it be simpler if we just had a mixed os/data partition?
09:16
Bertl
so that the root partition does not get cluttered and in the future can be read-only
09:16
Bertl
also it simplifies updating the OS
09:17
jarhab[m]
but what about package installs and linking the axiom-tools into /usr/local/bin?
09:17
jarhab[m]
isnt arch rolling release so its much simpler, if we have it on a rw partition and do pacman -Syu regulary?
09:18
Bertl
you can always remount a partition rw or ro if done properly
09:19
Bertl
running pacman -Syu on a regular basis is not the best idea, because you might easily end up with a defunct system
09:21
Bertl
unfortunately Arch is not always consistent on a MicroZed, so you need to know when you can update and when not
09:27
jarhab[m]
what do you mean by not always consistent? the kernel updates?
09:28
Bertl
no, kernel updates are not a problem as we roll our own kernel anyway, but sometimes userspace is in a state where it doesn't boot anymore
09:28
Bertl
i.e. libraries do not match the binaries, etc
09:29
jarhab[m]
ok
09:29
jarhab[m]
thats bad

davidak: it is pink?
13:40
se6astian
yes :)
13:40
se6astian
we suspect the bayer order is the issue
13:40
se6astian
I know we had this problem before
13:40
se6astian
but I found no solution on our wiki
13:40
se6astian
how did we deal with it?

se6astian
I am just reading https://github.com/apertus-open-source-cinema/misc-tools-utilities/blame/master/raw2dng/raw2dng.c
14:37
se6astian
and it seems that the bayer order is just a metadata tag in the DNG
14:47
Bertl_oO
hmm ... the simple debayer sequence (from the wiki) gives an interesting result
14:54
Bertl_oO
convert \( -size 4096x3072 -depth 12 gray:20171031_123147.raw12 \) \( -clone 0 -crop -1-1 \) \( -clone 0 -crop -1+0 \) \( -clone 0 -crop +0-1 \) -sample 2048x1536 \( -clone 2,3 -average \) -delete 2,3 -swap 0,1 +swap -combine 20171031_123147.png
14:55
Bertl_oO
how does that look to you?
15:05
se6astian
perfect!
15:05
se6astian
thats the right bayer order
15:05
