morning folk :)
09:39
jarhab[m]
how do you build u-boot and how do you assemble it into the image?

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

davidak: it is pink?
14:40
se6astian
yes :)
14:40
se6astian
we suspect the bayer order is the issue
14:40
se6astian
I know we had this problem before
14:40
se6astian
but I found no solution on our wiki
14:40
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
15:37
se6astian
and it seems that the bayer order is just a metadata tag in the DNG
15:47
Bertl_oO
hmm ... the simple debayer sequence (from the wiki) gives an interesting result
15:54
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
15:55
Bertl_oO
how does that look to you?
16:05
se6astian
perfect!
16:05
se6astian
thats the right bayer order
16:05
se6astian
