I'll try later today since I'm busy with other stuff now
10:24
<
Wizzup >
I never got the error that is mentioned in the commit
10:25
<
javier__ >
yeah me neither
10:25
<
Wizzup >
I think I should just get linux-next and give it a go from there on
10:25
<
Wizzup >
Possibly something broke along the way, he fixed it, and perhaps fixed the actual issue
10:25
<
javier__ >
but I'm chain loading u-boot so probably is because u-boot configures the master clock frequency correctly
10:25
<
javier__ >
and then it gets configured wrongly
10:25
<
javier__ >
that would make sense and will explain why the first time playback works but the second doesn't
10:26
<
javier__ >
Wizzup: his patch applies cleanly on top of 4.3-rc5 at least
10:26
<
Wizzup >
I am not sure if the first playback works 'properly', but it's almost properly
10:26
<
Wizzup >
javier__: I see
10:26
<
javier__ >
yeah, by some definition of properly :P
10:26
<
javier__ >
anyways, I'm just pointing out that commit since I don't have time to test now
10:26
<
javier__ >
and maybe you missed it
10:27
<
Wizzup >
yes, thanks!
10:27
<
Wizzup >
I did miss it, and I also do not have time atm, but I will try to test it asap
10:27
<
javier__ >
Wizzup: sure, no worries

Are there any successful attempts to reconstruct e5250 BL1?
13:01
<
Necrosporus >
is it user-replaceable?
13:10
krzk has joined #linux-exynos
13:31
<
Necrosporus >
I though analyzed the binary hexdump and it does not seem encrypted
13:33
<
Necrosporus >
Especially I wonder what is XXXXXXXX for and what repeating pattern of " ea fe ff ff " a3 69 c6 7a b4 ce 03 dc 6b d1 6f d4 6e c3 1c c3 07 00 00 ea fe ff ff ea ... does
13:34
<
Necrosporus >
Is it a sort of ARM nop?
13:36
<
Necrosporus >
It's only 1832 bytes of code worth and it should be relatively easy to reconstruct what it does, writing a free replacement
13:36
<
Necrosporus >
Since I was told BL1 is samsung proprietary
13:38
<
libv >
Necrosporus: you might want to put this in an email and send it to the ml
13:39
<
krzk >
And you can get a disassembler for armv7 on linux quite easily
13:39
<
Necrosporus >
I know, but I do not know a lot of things, so I would have to look up each instruction
13:40
<
Necrosporus >
I do not know any arm instructions at all, only x86 ones
13:40
<
Necrosporus >
And I'm not sure I want to learn all this stuff, I won't use it much anyway probably
13:47
<
Wizzup >
tried IDA?
13:52
krzk has quit [Quit: Wychodzi]
13:55
<
Necrosporus >
Wizzup, it's proprietary and for windows
13:56
<
Wizzup >
it also runs on linux, but please let me know of proper alternatives
13:56
<
Wizzup >
actually, I ran into one recently...
13:56
<
Wizzup >
I forgot the name
13:57
<
Necrosporus >
radare2
13:57
<
Necrosporus >
but not sure if it supports arm
13:58
<
zombah >
there is some freeware version of ida, i once tried it under wine, works fine if i remember right
14:01
<
Necrosporus >
zombah, I do not think it's released under a free software license with source code
14:02
<
Wizzup >
He said freeware
14:03
<
Necrosporus >
either way, I'm looking for someone who knows ARM assembly to do it for me and the benefit of society
14:05
<
Necrosporus >
Wizzup, do you know anything about bl1?
14:06
<
Wizzup >
no - not much, atm,
14:06
<
Wizzup >
there's 'darm'
14:08
<
Necrosporus >
What's darm?
14:09
<
Wizzup >
it is an arm disasm, but not what I meant... hang on
14:11
<
Necrosporus >
I have found it too
14:12
<
Necrosporus >
I researched the topic yesterday for a bit
14:12
<
Necrosporus >
There are certain people who might know something about bl1

javier__: just tried the patch on 4.2.2
14:20
<
Wizzup >
It's still running too fast
14:20
<
Wizzup >
but I am not sure if it gets 'more unstable' over time
14:20
<
Wizzup >
trying now
14:20
<
Wizzup >
It's really hard to hear the small difference
14:21
<
javier__ >
Wizzup: yes, then are separate issues. I wonder why I don't get the issue reported
14:21
<
Wizzup >
Perhaps people don't notice the difference
14:21
<
javier__ >
I tested both using a FIT image and chain loading u-boot in case is due a previous setup made by the bootloader
14:22
<
javier__ >
Wizzup: no, I mean the "max98090 7-0010: Invalid master clock frequency" reported by Alim
14:22
<
javier__ >
Wizzup: what's the MAX98091 REVID reported in your peach board?
14:22
<
javier__ >
REVID=0x51 or REVID=0x52 ?
14:23
<
Wizzup >
[ 2.107257] max98090 7-0010: MAX98091 REVID=0x52
14:23
<
Wizzup >
[ 0.000000] Machine model: Google Peach Pi Rev 10+
14:23
<
Wizzup >
So I just did: time mpv <foo>
14:23
<
Wizzup >
and compared the running time
14:24
<
Wizzup >
02:47 mpv time, real time 2:34
14:24
<
Wizzup >
>>> x / float(y)
14:24
<
Wizzup >
0.9221556886227545
14:24
<
Wizzup >
>>> 44100 / 48000.
14:27
<
javier__ >
strange, the same REVID than Alim, I thought that maybe that was the difference and why I was not able to reproduce the issue
14:28
<
javier__ >
Wizzup: I see
14:31
<
javier__ >
Wizzup: I didn't have too much time to test audio today but I'll plan to do more testing and ask Alim how he is testing it
14:32
<
Wizzup >
I am using pulseaudio, but let me see if I can fully eliminate it.
14:33
<
Wizzup >
I think it's still broken
14:37
<
Wizzup >
(so pulseaudio was not to blame)
14:39
<
Wizzup >
ok, I cannot find anything meaningful in the dts files
14:40
<
Wizzup >
going to stop the debugging for now
