<hanetzer> yo. someone suggest a good rk3288 or better dev board with full jtag support?
nighty- has joined #linux-rockchip
lurchi_ has joined #linux-rockchip
<beeble> hanetzer: jtag is muxed on the sd card pins on most boards. so any should work for you with a breakout board for an existing swd jtag device you have.
<beeble> ok mixed jtag and swd in a sloppy way
<hanetzer> beeble: oh nifty. don't suppose you could suggest one?
lurchi__ has quit [Ping timeout: 268 seconds]
<hanetzer> also, regarding the mali in the rk3288; can it be used for av encoding/decoding like one could with a 'normal' desktop gpu?
<beeble> do you have a swd capable debugger?
<beeble> an openocd bitbang device for example
<hanetzer> beeble: I have a flyswatter2 and am willing to acquire another device if needed :)
<beeble> https://www.sparkfun.com/products/9419 for a breakout board
<beeble> and for video en/decoding take a look at mpp instead of the mali
vstehle has joined #linux-rockchip
<hanetzer> beeble: yeah, mpp is being worked on for foss goodness, right?
<beeble> the flyswatter should work as it is just a ftdi based openocd adapter
<hanetzer> yah.
<beeble> not sure on how to answer you foss question. libmpp is available, there is a gstreamer plugin and ffmpeg supports it too in some way
<beeble> so it's opensource?

<eballetbo> Hi, the DMC binding documentation (https://www.kernel.org/doc/Documentation/devicetree/bindings/devfreq/rk3399_dmc.txt) defines 'rockchip,dram_speed_bin'
<eballetbo> In the documentation point to a non-existent file include/dt-bindings/clock/ddr.h
<eballetbo> Anyone can explain me what exactly is this parameter and where I can find more information?
<eballetbo> kever maybe? ^
<beeble> eballetbo: i can't say anything about the missing ddr.h but for speed bins take a look at JESD79-3F page 157
chewitt has quit [Quit: Adios!]
<hanetzer> would be really nice to get this grub2 as a coreboot payload working for my chromebook :P
<Ke> would be awesome indeed
<eballetbo> beeble: thanks, so if I understand correctly a rockchip,dram_speed_bin = <21> is DDR3-1066F (7-7-7)
<hanetzer> Ke: doing a slight bit of experimentation with it.
<beeble> eballetbo: that may be soc dependent? but not sure
<hanetzer> eballetbo: looking at the commit that introduced it, no such file was added
nighty- has quit [Quit: Disappears in a puff of smoke]
<eballetbo> hanetzer: yeah, that's why I was asking
<eballetbo> beeble: I suppose is both, dram and soc dependent? I mean one dram can support highest speed than the soc supports, in this case we just run dram slower than is able to do.
<beeble> eballetbo: i meant what <21> means.
<beeble> because thats DRAM3_DEFAULT in that driver and i think thats soc dependent. but only skimmed the driver

<mmind00> beeble eballetbo: but then again, it looks like an oversight that this got into a binding at all ... i.e. dt-binding should be descriptive (like having a real unit of sorts) and not contain hw-specific magic values
<beeble> mmind00: agree

<eballetbo> I am still learning about all this stuff
<Ke> hanetzer: how far along are you, perhaps you could even share the magic of the rom layout?
<Ke> hanetzer: I might even lie that I could help you
<hanetzer> Ke: there is no magick to the rom layout. just clone coreboot, menuconfig it to do veyron jerry, and feed it a self-made grub standalone image from git
<Ke> hmm, I don't have to preserve anything in the rom?
<Ke> also, I have Kevin, wonder if there is a difference
<hanetzer> nope. though I do suggest a backup. and what you see in the imgur link is what you get. doesn't get further than that.
<hanetzer> no keyboard input, internal or external.
<hanetzer> is kevin a veyron ?
<Ke> rk3399
<Ke> I have veyron-speedy as well
<hanetzer> unsure if rk3399 is 'supported' at all.
<hanetzer> 2gb or 4gb ram variant?
<Ke> supported where?
<hanetzer> in grub2
<Ke> 4GB both
<Ke> I thought grub uses EFI or something?
<hanetzer> ah. well, apparently the work I've done in u-boot works on the 2gb veyron speedy, but not the 4gb
<hanetzer> it can, but this is grub as a coreboot payload, different rules :)
<Ke> any idea, what's wrong with the 4G version
<hanetzer> ddr init
<Ke> though I might not be that much into throwing additional effort to speedy anymore, as I am planning to move to aarch64
<Ke> but I should learn to disable the beep there also
<hanetzer> nifty. don't suppose you know anyone really handy with soldering in texas? I need a tiny, very fine header put on to my speedy
<Ke> no
<hanetzer> if I had this header, I could prolly do a bit more good work to get something working to let you use 'normal' linux normally
<Ke> my local soldering child labour is leaving the company, so I am going to have trouble with that as well
<hanetzer> haha
<Ke> luckily he actually taught me most of the basics already
<hanetzer> I'm alright with the basics. some smd, lotta through-hole. but this is a very dickish part

<sphalerite> hanetzer: the serial port?
<hanetzer> sphalerite: hmm?
<sphalerite> for the soldering
<hanetzer> sphalerite: well, combo serial jtag etc port, but yeah
<sphalerite> yeah I'd really like to be able to use mine to… would make so many things so much easier

<Ke> hanetzer: I'll see, if I can
<Ke> hanetzer: not packaged in debian, so you are going to have to wait a while
<hanetzer> Ke: k. is this stock-ish flash?
<Ke> libreboot precompiled
<hanetzer> k. meaning, only the payload was changed, not the lowlevel init stuff
<Ke> yeah, I believe so
<Ke> ie. some blobs were removed and perhaps replaced and the payload hacked a bit
<Ke> it's still vboot, but has libreboot branding and does not make the unrtusted OS beep
<Ke> which is the most important feature of libreboot obviously
<hanetzer> hehe
<Ke> hanetzer: I guess cbmem will be a part of coreboot repo?
<hanetzer> Ke: honestly unsure. its present in stock chromeos
<Ke> .local/repo/mirror/coreboot/src/arch/x86/cbmem.c
<Ke> .local/repo/mirror/coreboot/util/cbmem/cbmem.c
<Ke> I guess it's there
<hanetzer> yep. guess that's it :P
<Ke> the former is probably some driver or something
<hanetzer> yeah.
<hanetzer> exactly what did you execute to get that?
<Ke> oh sorry -c
<hanetzer> yeah. this is like coreboot's dmesg. I only need cbmem -c | grep -i ram
BenG83 has quit [Quit: Leaving]
<Ke> mind you I am having minor malfunctions, like nvram variables? being off
<Ke> eg. boot from SD is no longer the default
<Ke> and crossystem prints out garbage
<Ke> nothing related to raminit to my knowledge
<Ke> Configuring PLL at ff760010 with NF = 400, NR = 9 and NO = 2 (VCO = 1066666KHz, output = 533333KHz)
<Ke> is that perhaps, what you wanted?
<Ke> I guess there is nothing too sensitive there to share it all?
<hanetzer> Ke: huh. dafuqs. you have a different ram config than I do
<hanetzer> this was a 4gb variant, yeah?
<Ke> yes
<hanetzer> prolly different ram chips
<Ke> Asus chromebook C201

<matwey> Hi. Could somebody please help me with ffmpeg and Rockchip mpp?
<matwey> ffplay -vcodec h264_rkmpp big_buck_bunny_480p_h264.mov
<matwey> I see the following error when run the command: mpi: mpp version: Without VCS, under bleeding [h264_rkmpp @ 0x7f7006f640] Decoder noticed an info change (854x480), format=0 Impossible to convert between the formats supported by the filter 'ffplay_buffer' and the filter 'auto_scaler_0'
<matwey> How could I run ffplay with hardware h264 decoding?
<Ke> in general h264 is a family of codecs, perhaps that one is just not supported?
<ayaka> matwey, the problem is that, the video change its resolution
<ayaka> the gstreamer can handle it as the products request it
<ayaka> but ffmpeg is not supported official
<matwey> ayaka: is resolution rescaling handled at hardware too?
<hanetzer> is there a way to get a shell over the otg port on rk3288 hardware?
<ayaka> matwey, no, but its the video stream that change its resolution
<ayaka> the hardware decoder don't care about it, but it would notify the external application
<matwey> It is just test file from Big Buck Bunny. Should I try another h264 video?
<ayaka> yes, you should
<matwey> Hm, sintel-1024-surround.mp4 shows the same behaviour
<ayaka> ok it seems that you didn't use the drm overlay
<matwey> How could I use it?
<ayaka> I don't know
<matwey> What is the general difference between ffmpeg and ffplay?
<matwey> ffplay seems not to have hwaccel option
<ayaka> you may ask the #ffmpeg
