<hanetzer> now I get garbage output after 20080000.serial: ttyAMA0 at MMIO 0x20080000 (irq = 26, base_baud = 0) is a PL011 rev2, progress!

<Antitrack> hanetzer: which ARM board are you using exactly ?
<hanetzer> Antitrack: consumer device. unsupported in mainline, shit linux-3.4.x/u-boot-2010.06 bsp. Hi3535.
<hanetzer> wrote a clock driver and dts for it :)
<Antitrack> wow
<Antitrack> you can do dtb dts stuff ?
<Antitrack> for kernel 3 , 4 or 5 ?
<Xogium> I'm guessing the goal is to mainline it, so I'd assume 5
<hanetzer> 5
<Xogium> 3 didn't have dt afaik… or if it did it was probably a lot more primitive :D
<hanetzer> I mean, aside from stupid pitfalls dts stuff isn't that hard.
<Antitrack> I'm working on odroid c4 , but kernel 5 has problems all over. bad/slow video driver, UART getting only ready after 30 secs, slow u-boot makes booting a 50sec pain-experience due to i2c bugs, etc.etc.
<Xogium> its certainly more fun than crappy acpi *cough*
<hanetzer> Xogium: or a million board files.
<Antitrack> I once messed with a dtb file for kernel 3 and odroid c2 to enable all uarts - it was one file and it worked.....
<Xogium> Antitrack: ouch, that's not nice
<Antitrack> and I have no real idea how to fix all these issues, or when they will be fixed. seems to dangle on one single lonely kernel developer, "tobetter"...
<hanetzer> on another note, KASAN is very useful for figuring out why shit is borked :P
<Antitrack> KASAN?
<Xogium> sigh… the joys of sbc barely supported in mainline because the vendors don't bother upstreaming
<Antitrack> I googled for Kasan, but I am only getting a town in usbekistan
<j`ey> Antitrack: kernel address sanitiser
<Antitrack> ah
<hanetzer> Xogium: heh. yeah, this and similar chips are all over the world in cctv/nvr devices.
<hanetzer> not a good look to have old ass kernels in them.
<Xogium> hanetzer: I know right ? I tried to make the mangopi work
<Xogium> typical chinese sbc trying to take over the world and failing. Armv5
<Antitrack> "mangopi"! (soon they are gonna run out of fruit names...!)
<Xogium> Antitrack: yup they'll have to go with vegetables ;p
<Antitrack> :-)
<Xogium> honestly I tried but… ugh. Even the vendor kernel was a mess (no surprise there), they actually did not give the kernel
<Xogium> they gave me the buildroot, though ! ... with a 3900 lines long patch to add support for the board
<Xogium> for kernel
<Xogium> so kile you take this 4.4.99 mainline and stick their giant patch on top
<Xogium> *like rather
<hanetzer> heh. I had to get the sdk for this chip (and similar ones) from taobao lmao
<Xogium> good luck finding something broken in there
<Xogium> I mean… goodness sake. At least have the decency of splitting your changes into multiple patches
<hanetzer> heh. they didn't even give patches. just a prepatched tarball
<Antitrack> did anyone use buildroot to get a system working for odroid c4? the original docs from hardkernel give me some compile error, nothing else
<hanetzer> it says its 3.4.35 in the root Makefile but there are changes which are obviously backports :/
<Xogium> hanetzer: ouch that's even more mean than what I got…
<hanetzer> and I haven't even gotten around to working against their blob drivers lmao
<Xogium> Antitrack: fwiw upstream buildroot doesn't have support for c4 only xu4 and c2

<milkylainen> Xogium: I dunno what the problem is. There is apparently enough people caring and updating/fixing the code? Does it need to have an active maintainer?
<milkylainen> Generic fs stuff?
<milkylainen> Should be enough of those anyway.
<Xogium> milkylainen: I saw that it is already orphened
<Xogium> the guy who submitted it in one patch only is already unresponsive and hasn't bothered replying to emails or anything
<milkylainen> Does that really mean anything? It's not like all original authors of everything is still actively maintaining their babies.
<milkylainen> Yes I know.
<milkylainen> It's been covered everywhere. Reason for coverage = people care.
<Xogium> oh, didn't know it had been

<marex> hanetzer: the electrons have to flow through somewhere from gnd to vcc ;-)
<hanetzer> blerg tho. oh well. I have a device that doesn't pop whenever you plug it in lmao
<marex> oh, so its just dead ?
<marex> did you solder onto the device ? or touch with a probe in some wrong spot ?
<hanetzer> idk if its dead. a LED that's normally off unless you flip the switch is now on if its plugged in
<marex> did you try turning it off and on again ?
<hanetzer> regardless of the switch position.
<hanetzer> yes :P
<marex> and the led does what exactly ?
<hanetzer> just constant on
<marex> if the led is on, it means there isnt a short to ground ?
abelvesa has quit [Quit: leaving]
abelvesa has joined #armlinux
<marex> if there was, it would draw much more current, your PSU would likely shut down
<hanetzer> I mean. normally, you have to 1. have it plugged in and 2. have the switch flipped to the 'on' position for it to be lit.
<hanetzer> now, its constantly lit if its plugged in.
<marex> maybe the switch just broke from too much switching
<hanetzer> (also the usb/ttl device I was using fried :D)
<marex> oh
<hanetzer> yeah. something is seriously fubar'd.
<hanetzer> I even desoldered the switch in case that was it, nope, still lit.
<marex> maybe the power is flowing from the USB-serial adapter ?
<hanetzer> this is without the serial adapter plugged in.
<marex> there might be 3V3 LDO on it, or 5V outright from the bus
<marex> ha
<hanetzer> worst thing, nothing looks like it has released its magic smoke
<hanetzer> could be the psu itself is fucked lmao
