<mmind00> naobsd: nice ... thanks for finding this :-) ... I don't monitor the uboot list so closely and it's really cool that Rockchip seems to also migrate to mainline uboot

<naobsd> I didn't notice Rockchip/Chipspark supports hw accelerated ffmpeg for Linux
levd has quit [Ping timeout: 250 seconds]
levd1 is now known as levd
<naobsd> I never tried but looks nice
<sjoerd> naobsd: the chrome os kernel apparently has a v4l2 decoder, which is becoming the standard interface upstream
<sjoerd> hopefully that'll land upstream at some point
<naobsd> sjoerd: ah, surely, it should be better
<sjoerd> Nod
<sjoerd> not sure if ffmpeg supports it, but gstreamer does these days so that would allow hw decoding to just work without any platform specific code
<naobsd> btw I'm resurrecting my develop environment at home... now u-boot v2015.10 +linux-next-20151022 multi_v7_defconfig is running on RR2
<sjoerd> \o/
<sjoerd> i've got some more bits and pieces in the pipeline for RR2
<naobsd> SD card slot seems not working after kernel run ;)
<sjoerd> huh?
<sjoerd> that's not something i've seen before
<naobsd> mmcblk0: error -110 sending status command, retrying
* sjoerd wonders if something landed in next which broke that
<sjoerd> mmcblk0 is the emmc though i think ?
<naobsd> eMMC, mmcblk1 seems to be working
<sjoerd> curious
<naobsd> SD slot is working on u-boot (I wrote u-boot on SD)
<sjoerd> right
<sjoerd> can you pastebin your full dmesg somewhere?
<sjoerd> mmind00s tuning stuff didn't go towards next right?
<naobsd> sjoerd: I'm not sure status of latest patches... probably not yet
<sjoerd> ugh that's really unhappy
<sjoerd> haven't seen that before
<sjoerd> would be worthwhile if you could try with another card to see if it's specific to the card or
<naobsd> yup
<naobsd> I have some unreliable uSD cards
<naobsd> but I'm not sure which one is it ;)
<naobsd> I'll try another cards
<naobsd> btw size of ram is not correct. it should be 4GB
<sjoerd> Nod i noticed last week
<naobsd> I should check u-boot
<sjoerd> I thought i got the 2G model, but turned out i have the 4G one indeed :p
<sjoerd> Please
<naobsd> oh :)
<sjoerd> Would be good to know if the SPL determines the amount of ram right or not
<mmind00> sjoerd: tuning is in next ... but normally this would get enabled per-board (mmc caps and also possible voltages)
<sjoerd> ah right
<sjoerd> so that won't be naobsd's issue ;)
<naobsd> ah, thanks :)

<chris__> Hi all, curious if anyone has ever tried dual-booting in nand by making a parameter file that points to partitions in alternate places
<chris__> I'm trying to port clean sources to an unsupported rk3128 board, and while it mostly works I'm doing a lot of swapping back and forth with the original
<chris__> flashing all of which (and then letting art optimize everything on boot, etc) takes a while. I don't want to use an sdcard because on the rk3128 that is exclusive of serial
<sjoerd> naobsd: oh that reminds me now that you're playing with upstream u-boot, I'd love to be able to load upstream u-boot in maskrom mode.. Seems sjg got it as far as uploading the SPL but doesn't know how to trigger the rom support code to e.g. download the second stage loader
<chris__> I was thinking if I could split the 8g nand in half I could have two systems, and just quickly rockusb-flash the param file pointing to whichever one I want
<chris__> It seems to be working - a few gotchas such as uboot only handling 19 partitions or so therefore I don't list all the alternate ones in the parameter file
<chris__> And somehow the last partition seems to grow to the size of the nand
<chris__> had to manually reformat the user_data and user partitions
<chris__> but in theory it looks like flashing alternate parameter files will be a quick way to dual boot for A/B testing
<chris__> Putting the switch in u-boot would be the next step...

<chris__> It turns out you can decompress a kernel 'piggy'; patch it; build a similar tree; copy your patched version over arch/arm/boot/Image; touch it ; make zImage ; flash the result and have it work! Now I just have to dump the data from the calls I'm intercepting in the binary kernel...
