<montjoie> does someone already booted big endian kernel on sunxi ?
<montjoie> My BE kernel is stuck at "booting the kernel"
<anarsoul> montjoie: but why?
<montjoie> for testing purpose
<KotCzarny> wouldnt you need cpu configured in BE mode before starting kernel?
<montjoie> in fact it booted it was just very long:(
<KotCzarny> o.o
<montjoie> i need to test my crypto driver on BE
<KotCzarny> do you know of any real users using it?
<montjoie> no but I want to be sure to submit a good driver
<montjoie> and perhaps found some crash in other driver to fix:)

Svenska has joined #linux-sunxi
<Svenska> Hi. I am trying to build a mainline U-Boot for an A33 tablet (1024x600, 1 GB), but when I try to boot from it, nothing happens (backlight does not turn on). I tried different versions of U-Boot (between 2016 and v2018.09), and both gcc 6 and gcc 8 to build. Also, I found an old SD card which used to work on a different Q8 tablet (same specs), but which broke.
<Svenska> In addition, I extracted the script.fex file and tried both the default values and the values from there.
<Svenska> The FEX file is available here: https://pastebin.com/9iMETEtQ
<Svenska> Without a serial console, what are the main suspects why it doesn't work?
DonkeyHotei has quit [Remote host closed the connection]
<Svenska> Does anyone have experience with a Q8 tablet, or can point me to some resources or hints?

<Svenska> The model number is "QT-7", processor type is "QuadCore-A33", kernel 3.4.39 and the build number is "A0720BS3_1024x600_4.4_20180608".
<KotCzarny> have checked the wiki?
<Svenska> Yes, a lot, but I don't know what to even look for.
<KotCzarny> similar devices, q8 is a form factor
<KotCzarny> main things to work towards is: a33 soc, then display panel and touchscreen
<KotCzarny> that usually covers most hurdles
<Svenska> Touchscreen is gsl1680, display is "default_lcd"
<Svenska> I thought that most Q8 tablets share most hardware. How are the panels different, and where do I set up U-Boot?
<KotCzarny> as for serial console, i think it's multiplexed with uart0
spuniunHs has quit [Ping timeout: 268 seconds]
<Svenska> ...that is something I do not have access to.
<KotCzarny> this one seems to be a33 based too
<Wizzup> Svenska: maybe try the devuan u-boot for a8 tablets, that one worked OOTB on my q8-like tablet
<KotCzarny> as for the lcd, there are few display interfaces possible
<Wizzup> s/a8/q8/
<KotCzarny> and i think not all are supported in mainline yet (or are they?)
<Svenska> There are many, and most seem to work using the same device-tree and u-boot configuration (depending on display resolution) - it worked on a different Q8 tablet for me as well.
<Svenska> Devuan U-Boot?
<KotCzarny> ie. mipi dsi vs rgb/lvds
<Wizzup> Svenska: oh, so just this -specific- q8-like tablet doesn't work for you
<Svenska> Wizzup: exactly, and it doesn't work with an older sd card either
<Svenska> KotCzarny: that should be easy to find out from the FEX file, right?
<KotCzarny> i think yes, but i'm only hinting, have hacked my a23 based tablet yet
<Svenska> I see "lcd_used = 1, lcd_if = 0, lcd_lvds_if = 0, lcd_dsi_lane = 4"
<KotCzarny> http://linux-sunxi.org/Fex_Guide#lcd.5B0.2F1.5D_configuration
<Svenska> hmm, that's a good point. this seems to be a dsi lcd, then
<KotCzarny> here is the table to decode those
rellig has joined #linux-sunxi
<KotCzarny> lcd_if=0 is 'hv (sync+de)', whatever that means
rellig has quit [Killed (Sigyn (Spam is off topic on freenode.))]
chomwitt has joined #linux-sunxi
<Svenska> probably separate sync signals (horiz+vert), seems common
<KotCzarny> this seems to be related too
<Svenska> yes, that's what i have used to change the display timings
<Svenska> they were quite close before, but i have adapted them to match the FEX - to no effect
<KotCzarny> if there is no backlight, maybe you've missed some gpio
<Svenska> yes, it might be that the pwm pin is inverted
<Svenska> ...nope.
DonkeyHotei has joined #linux-sunxi
<Svenska> another thing which seems different from other examples is: lcd_power = "axp22_dc1sw"

<DonkeyHotei> Svenska: you should create at least a skeleton page for it, like so: http://linux-sunxi.org/Naxa_NID-7015
<Svenska> okay
<Svenska> not now, though - time to sleep. :-)
<DonkeyHotei> just note: so far, i haven't had much luck with legacy OR mainline kernels
<Svenska> on the same kind of system?
<DonkeyHotei> i linked it
<DonkeyHotei> fex file is on that page
<Svenska> before i broke my other Q8 tablet, i had u-boot and kernel running (but no touchscreen - which is what i was working on when i dropped it)... so at least sometimes things seem straightforward
<Svenska> hmm, the devices seem very different, except for the lcd_power :-)
<Svenska> anyway, thank you for your help :-)
