<suprothunderbolt> hanetzer: sorry for the delayed reply! Mali on the A64 using the binary blobs but open to anything else and wayland well, anything. I'm keen to get current QT to work in EGL mode if possible
<suprothunderbolt> what ever is the easiest way to get Qt to work with a current mainline kernel
<hanetzer> suprothunderbolt: is that lima mali or panfrost mali?
<suprothunderbolt> lima mali but running in the binary blobs
<suprothunderbolt> I haven't tried Lima
<suprothunderbolt> I followed this : https://github.com/mripard/sunxi-mali
<suprothunderbolt> the module gets loaded fine but it doesn't seem like wayland or QT can find the libraries
<suprothunderbolt> though I copied them across and I've run ldconfig. Not sure if there a way to get more debugging info from wayland
<hanetzer> can try LD_DEBUG stuff
<hanetzer> I try to avoid trying to make mali work with the blobs, so I'm sorry I can't help much there
<suprothunderbolt> did you get it to work okay with Lima?
<hanetzer> nope. I only have panfrost-capable mali :)
<hanetzer> which is why I was asking :)

<suprothunderbolt> is there a downside to using the fbdev or other backend? Or is there a specific version of the mali blobs I should attempt to use?

<suprothunderbolt> so far nothing...
<suprothunderbolt> the wayland blobs seem to get found according to LD_DEBUG but don't run
<suprothunderbolt> warning: either no EGL_EXT_platform_base support or specific platform support; falling back to eglGetDisplay.
<suprothunderbolt> failed to initialize egl
<suprothunderbolt> not sure where to look next

<DuClare> willmore: Too bad I don't have a scope :( And the chip is in a location where it might be impossible to scope without soldering some leads..
<fALSO> i also really wanted to have a scope
<fALSO> but people in portugal, ask big sums of money
<fALSO> for scopes with 15, 20, 30 years

<willmore> fALSO, I didn't have a scope for years despite doing a lot of design work. I finally had a fellow amateur radio hobbiest give me one when he found out. I still have it. I did buy one of my own later which I use often. Yeah, if you're doing electronics, you need a scope.
<fALSO> im not a master
<fALSO> im play with arduinos, and stm32 and stuff like that
<fALSO> i preffer more the "programming part"
* karlp uses the LA far more than the scope.
<mru> both are very useful
<fALSO> LA?
<fALSO> ahh logic analiser
<fALSO> i have a imitation of SALEA from china
<fALSO> even works with the original software :-P
<mru> I like my tektronix all-in-one
<mru> 4ch scope, 16ch logic, 3 GHz spectrum analyser
<fALSO> awesome
<karlp> I bet you like the price too... :)
<fALSO> nop
<fALSO> LOL
<aalm> :E
<mru> it wasn't exactly cheap...
<aalm> logic analyzers mostly do it for me too, so i just give up whatever i'd need a scope for.. :D
<mru> guess you've never debugged a power supply problem
<aalm> nope, but i've replaced many.. :/
<mru> a scope is also necessary if you have signal integrity issues
<mru> a logic analyser won't tell you things like rise time
<karlp> Iw ould never say "don't buy a scope" or "scopes are useless"
<karlp> but a lot of software people who need more insight can/shoudl probably prioritise an LA over a scope. (explicitly talking abotu software people here)
<aalm> that's not what i meant either, i sure would like to have one avail. at home.
<fALSO> its a pretty cool piece of equipment to have on your work table ;-D
<fALSO> makes you look like a PRO
<fALSO> :-PPPPPPPPPPPPPPPPPP
<mru> when working on embedded designs, software problems can quickly turn into hardware problems

<aalm> mru, seems like your scope does cost just about as much as all my arm hardware in total, or even more.. :x
vagrantc has joined #linux-sunxi
<KotCzarny> but question is.. will it blend?
<aalm> xD

<mru> the scope has an arm cpu too
<mru> it's an MDO3024 fwiw
<fALSO> do you guys watch eevblog?
<fALSO> love that dave jones
<fALSO> ;-)
wwilly has quit [Quit: Leaving]
<mru> the forums are good too
<mru> found a script to generate feature unlocking codes for the scope there
<fALSO> yes, he loves to hack those
<fALSO> ;-)
<mru> too bad the probes don't upgrade themselves though
<fALSO> hehe

<willmore> Low end LAs are so cheap, it's silly not to have one. The salea clones are just a few dollars and work well up to, what, 24MHz sample rate? Pulseview works wonderfully, too.
<willmore> +1 for Dave
* willmore may or may not have a fully unlocked scope as well....
<DuClare> I'd rather have a scope though
<DuClare> And preferrably not a low end one :P

<red_devil1980> Hi everyone, i tried to install debian testing/buster on my Cubieboard 4, but it does not find the mmcblk0 during startup and drop to initrams built-in shell. Is anyone here running recent kernel on that board?
<vagrantc> there are a lot of things missing for Cubieboard4 support in debian
<vagrantc> i think ethernet support is coming in the kernel, but not going to be available for debian buster
<red_devil1980> is this a debian issue or a lack of features in the kernel?

<vagrantc> red_devil1980: probably some of both ... there may be features that work upstream that haven't been enabled in the debian kernel, or modules that aren't present in the initrd, etc.

<red_devil1980> i'm not glad to read this. i'have not really understood how arm devices work, so i would not trust me in configuring a kernel from scratch. Here, the kernel claims "sun9i-a80-pinctrl 6000800.pinctrl: 6000800.pinctrl supply vcc-pg not found, using dummy regulator" and so i hoped it could be adjusted in the dts or dtsi files.
<vagrantc> cubieboard4 also doesn't really have USB support properly upstreamed, from what i understand ... so it's pretty limited in some ways

<red_devil1980> sounds for me, that the best idea at the moment for someone like me is to use the ancient debian image they provide on their repos.
