It looks like some driver is missing in my windows machine. Do you know where I can find those?

This driver should be installed to flash RK devices under windows machine.

OK - The memtester run from yesterday completed successfully.... eventually.

I then did some calcs in a spreadsheet. The total delays using the default kernel values seem incredibly short.... unless regulator_enable_ramp_delay defaults to a non-zero value if undefined, but the documents don't suggest there is a default

Defaulted Kernel dtb values

dV	dμV	regulator_enable_ramp_delay (μs)	regulator_ramp_delay (μV/μs)	delay (μs)
0.025	25000	0	12500	2
0.05	50000	0	12500	4
0.075	75000	0	12500	6
0.1	100000	0	12500	8

jock2 recommended the following, considerably longer delays generally.

dV	dμV	regulator_enable_ramp_delay (μs)	regulator_ramp_delay (μV/μs)	delay (μs)
0.025	25000	0	300	83.33333
0.05	50000	0	300	166.6667
0.075	75000	0	300	250
0.1	100000	0	300	333.3333

my initial "guess" values actually result in an overall delay in the same ballpark as jock2, and seem to work fairly well also....

dV	dμV	regulator_enable_ramp_delay (μs)	regulator_ramp_delay (μV/μs)	delay (μs)
0.025	25000	300	6000	304.1667
0.05	50000	300	6000	308.3333
0.075	75000	300	6000	312.5
0.1	100000	300	6000	316.6667

I then tried to find where the sweet-spot might be, working from low overall delay, and increasining to get more uptime... I've had my board running for > 10 hours with the following settings.... which is a massive improvement...

dV	dμV	regulator_enable_ramp_delay (μs)	regulator_ramp_delay (μV/μs)	delay (μs)
0.025	25000	100	5000	105
0.05	50000	100	5000	110
0.075	75000	100	5000	115
0.1	100000	100	5000	120

However.... Although the Librelec OS has been up > 10 hours, Kodi.bin partially crashed after 70minutes....

The IR LED was still responsive, and I could ssh onto the box and actually shutdown kodi using systemctrl stop kodi, and then I ran another memtester over 825MBtest, which is nearly finished now...

There was no kodi crashlog, as kodi was still running to some extent, but there were dmesg errors for the time the clock had stopped on the UI (09:15) . With 3 messages like this...

There was a corresponding kernel error...

Does this look like an OS, or do you think its a Kodi issue?

Any help would be great.

Thanks,

What about CPU temp? Errors in CPU calculations are very likely when operating at high temperatures.

My RK3228A freezes every 20-30 min without radiator.

Hello @ilmich,

Some bugs or benefits were found, not sure what this is, so far

Anyway, I see when box is suspended it can be woken up by any type of remote and any type of key.

Not sure if that's how it was meant to be, but I think it's not good when you are trying to turn off a TV, for example, box is waking up.

And second one is that the box wakes up automatically every 20-24 hrs. Not sure if only I have those issues. Please confirm, guys, if someone has the same.

Hello Everyone.

Actually I'm also struggling because of removing "Sync playback to display". Totally all 24fps video is not smooth even when frame rate is set to 24Hz manually. Is there any chance to enabled it in some xml configuration files?

BTW, I'm not using LEv10, only this unofficial builds based on LE-9.2/9.80

Thread

[unoffical] LE-9.2/9.80-Images for RK3229/RK3228

Maybe you bought a RK3229-Device some years ago and thought: Oh what a buggy chinese grap ... and tostedt into trash ... but wait: maybe you didn't ... just look for it in the boxroom, storeroom your whereever you put stuff you 'maybe need later' ... Since current Rockchip 4.4-Kernel supports it I added support to current LE-9.2 branch - it works nice - so why not publishing it - mainline Images build against a recent 9.80 tree now available too)

Hey, just found, this is awesome. Boots on my bad cheap Russian TV box - Iconbit XDS84K (1G, 8G, RK3229). Everything except Wi-Fi works, it seems, with the image: rk3229-a95xr1.img.gz from the first post. Enough for me to just daily drive it. I don't know of any forks and stuff.

However, the UI runs at like 10-20 fps, which isn't all that good. Scrolling is a big pain. The videos work just fine though, and the player UI when playing a video is smooth as butter. Any fix?

Quote from captainkrypto

Not a huge deal, but I am guessing this can't be changed once I flashed it to NAND?

If it will be flashed without changes in image - so yeah, most likely there won't be an ability to change device tree file, cuz the flash partition in RO mode by default. As long as the image is on SD, it can be easily edited from a PC.

Quote from captainkrypto

I have the same TV Box - MXQPRO4k. I used the mxqpro4kpro image from ilmich last update. Everything runs great with 720p resolution. Still shows a red light when on instead of blue, but whatever.

leds can be easily fixed by editing dtb file

Quote from ilmich

Hi shMatrix, to optimize even further, in the next build I've disabled some kernel options used by developers (aka debugfs).

This can improve something, but I don't expect miracles.

My suggestion is to try with another image considering that the one for mxq4kpro is for rk3228a. This soc in teory should have a lower clock for cpu and gpu (see first post for details).

Often these boxes are sold as a model, but internally they may be different.

For example mine is an mxq4k, but the board is identical to the one present in v88 mars

So check in the first post if there is an image that is similar to the one you use(ddr3, same wifi chip, same internal memory etc etc), but suitable for rk3229 / rk3228b and download it from my gdrive.

I tried absolutely all your last images and all of them work equally (16-19 fps), with the only difference being that sometimes led is working properly, sometimes not. Anyway I've increased performance via overclocking. So thank you very much for the great work.

Btw, do you know how to return "Sync playback to display" options which is in the original KODI?

Dear @ilmich, Is there a chance to increase performance a little more? As I said, currently GUI works much faster than previously but still slower than on stock firmware (15-19 vs 35-40 fps) and the main problem is random micro freezes while playing 1080p video, aprox 1-2 mins.

Quote from ilmich

try with this image

https://drive.google.com/drive/folders/…_yzM7Z00j9DVYh8

and let me known

this test build fixed my KODI crushing issue after closing particular types of files

advice please how to get dmesg output when any network connection doesn't work?

Quote from ilmich

Hi,

last update for my libreelec-9.2 fork:

- updated some packages

- fix hardware decoding (revert rkmpp version)

- improvements for ssv6051 wireless chip (thanks to fabiobassa and jock2)

- switch to better kernel scheduler and cpufreq governor

- some fixes for NAND setup

as usual I've builted all the images.

Tried this last libreelec-9.2 fork on my MXQ 4K PRO (MXQ_RK3229_EMCP_V3.1) and it works incredibly cool! Thanks for amazing work!

Founded benefits:

- starts and works much faster than any previous build

- even AFR works

- some types of files don't crush while original 18.9 KODI does on RK322x platforms

Founded issues:

- all network interfaces did not work at startup on my model, but after a couple of reboots wired connection started to work, but S9012P wifi still is not initialized, most likely due to the lack of a driver (not problem for me, using only wired LAN)

- AFR sometimes doesn't work correctly, with a quick glance it's not switching to 24 Hz

- closing\stopping some types of files leads to a reboot ( for example after playing this stream, it reloads stably http://rtmp.one.by:2300 )

Ready to provide any logs if needed.

Hello everybody and thanks for the real cool project.

Only this https://drive.google.com/drive/folders/…3wd66j4syhLVBdA experimental build from ilmich works on my MXQ_RK3229_EMCP_V3.1, but unfortunatelly too laggy, GUI looks like 7-8 fps. 720p screen resolution helps a bit, but still slow. I can see 50-80% cpu loading always, not sure why.
