<stdint> Myy, Korean today
<Myy> Yup !
<Myy> I'm trying to understand why the mpp_test is getting no informations from the VPU
<Myy> And yet, it does not display error messages like "Can't find the VPU" or "Unknown platform"
<stdint> I could read a few difference Asian language but the Korean is excepted
<stdint> Myy, it won't
<Myy> it won't display error messages ? Or find the right VPU informations ? :)
<stdint> the platform detecting method comes from me, it only use dts information and check a few device node
<Myy> Oh
<Myy> I guess that the best way to test it is to install MPP directly, use gstreamer and give it a shot then ?
<Myy> Also, I'm unable to force MPP to avoid compiling static libraries. Even though I defined -DENABLE_STATIC=OFF -DENABLE_SHARED=ON
<stdint> Myy, which branch?
<Myy> The develop one
<Myy> According to git branch
<stdint> Myy, use the for_linux branch
<Myy> Alright
<Myy> Oooh, it compiled !
<Myy> I'll try vpu_api_test then, with a simple MP4
<stdint> Myy, rk3288?
<Myy> Yup
<Myy> MiQi board
<stdint> I didn't add the supporting for MPEG-4 Part 10 for that soc
<stdint> Myy, have a try on mpi_dec_test
<Myy> Is H264 ok ?
<stdint> the input file could be found here
<Myy> Oh !
<stdint> Myy, only vp8, jpeg, hevc, avc is supported at rk3288
<stdint> the decoder
<Myy> Alright
<stdint> ok, I found I have not upload it
<Myy> I'll try with Big Buck Bunny
<Myy> WebM format will do then ? (VP8)

<stdint> Myy, it can't accept any video contents
<stdint> you need raw bitstream
<Myy> Ah, without the headers then
ganbold has quit [Quit: This computer has gone to sleep]
<Myy> So I extracted the datastream, using mkvextract tracks "bigbuckbunny.vp8" --raw 1:video.vp8
<Myy> And then using mpi_dec_test returned that : https://ghostbin.com/paste/dufc3 I'll try to see if I can run MPP directly on the Debian box this evening, see if I can get something with it.
<stdint> Myy, let me upload a image for you
<Myy> Alright
<stdint> there is a file named as 0008_intel_avc_1080p.avc

<hardik_> Hi everyone, how to stop uboot (rockchip loader) to get uboot command prompt?
<beeble> is bootdelay set to -1 ?
<hardik_> no
<hardik_> in parameter file i did set it to 10 but it's not stopping
<beeble> ah you want to get the prompt. not the other way around. sorry for missunderstanding
<hardik_> can i do it using command line parameter ?
<hardik_> and what is recovery partition ?
<beeble> sorry, i'm not familiar with the rockchip loader tool, never used it. but if you are using a mainline u-boot setting CONFIG_BOOTDELAY via menuconfig should be enough. to be sure you can set it to -1 that should always give you a prompt
<hardik_> ok
<hardik_> no source code for bootloader
<hardik_> it's a close source
<hardik_> i mean rockchip loader
<beeble> what board/soc do you have. you may not need it anyway
<hardik_> rk3188
<hardik_> and parameter file i'm using is https://pastebin.com/0dUY8ea7
<hardik_> read only flag " ro " also not working with mtdparts
<beeble> mainline u-boot seems to have spl/tpl support. but that my be not what you are looking for
<beeble> but i'm only familiar with the mainline stuff
<hardik_> i think i'm doing something silly mistake ....this CMDLINE in parameter is to do kernel configuration ...and i'm trying to set u-boot variable there
<mmind00> hardik_ beeble: yes rk3188 can now also use mainline uboot ... but of course that relies on a devicetree being available for the board and rk3188-boards in their kernel 3.0 days were still using boardfiles
<hardik_> mmind00, yes
<hardik_> then i need to go for latest avaialabe kernel for rk3188
<mmind00> hardik_: also, most board follow Rockchip's reference design pretty closely, so you should even be able to see some output when using the radxarock board that we currently support there
<hardik_> i have custom board based on olimex rk3188
<hardik_> Ok, i have main work to create some partition on emmc ...1) recovery + readonly 2) user space 3) backup
<hardik_> i can create partitions but don
<hardik_> *don't know about recovery and read only
<hardik_> if anyone experienced the same ..plz share

<hardik_> why we need both images kernel.img and boot.img to boot rk3188 ?
<phh> well, there are two configurations for rk3188 bootloader, either just boot.img which is kernel + initramfs, or kernel.img + boot.img, in which case boot.img is used only for initramfs, not kernel, to save space with recovery
sunxi_fan has joined #linux-rockchip
<hardik_> phh: boot.img consist of kernel image + ramdisk
<hardik_> ..right?
<phh> well, it's not supposed to contain kernel when you have a kernel.img
<hardik_> phh: means we don't have to do "mkbootimg --kernel RK3188-SOM/arch/arm/boot/Image --ramdisk initrd.img -o boot.img"
<hardik_> *when using kernel.img
<phh> yes, --kernel /dev/null
<phh> that's what I remember at least, I could be wrong
<hardik_> i'm not able to find any initramfs case in any guidline........everyone using ramdisk
<hardik_> *for rk3188
<phh> initramfs is the same as ramdisk
<phh> well rather, ramdisk is something that has been obsoleted like a decade ago, and everyone is actually using an initramfs
<hardik_> RK3188-SOM/arch/arm/boot/Image and kernel.img is same ...right?
<phh> hum, no, I think kernel.img has an additional header
<hardik_> for kernel.img using olimex kernel and all other rockchip loader(uboot),parameter.emmc, boot.img from manifest
<hardik_> and technique to flash also from rk3188-manifest site
<hardik_> so here kernel.img and boot.img (Image+initrd)................kernel.img and Image are different ......but no problem in booting and modules are working as expected
<hardik_> i meankernel.img and Image from differnt kernel

<micken> ayaka: do you know why HDMI offsets are *4 ? Makes it very hard to use them as offsets in assembler..
JohnDoe_71Rus has quit [Quit: KVIrc 4.9.2 Aria http://www.kvirc.net/]
lkcl has quit [Ping timeout: 240 seconds]
<phh> micken: because they blindly plugged hdmi controller which is 8 bits to the 32bits axi would be my guess
<micken> phh: yea
<micken> but still
<phh> (actually, I'd say it is a rather good idea, except for the fact that this makes other drivers incompatible)
<micken> I have a i.MX6 driver I need to adapt
<micken> and its all in assembler
<micken> using STRB r1,[r0,#offset]
<micken> and that offset is defined as the offset of the hdmi
<micken> this works however LDR r0,=#base + offset
<micken> even if the offset is a * 4
<micken> bah
<micken> using <<2
<micken> :)
