Starting from the official LE-12.2 (latest today), I was able to port ilmich 's le12-rk322x-wip on the latest. Had to remove a couple of the RTL81xx drivers as they were not easy to compile on latest kernel, but re-enabled 8723CS so my T95d box has wifi again!

There's probably more to tidy up, but I've aimed at maintaining all RK3xxx there (not tested).

Attached: git diff official/libreelec-12.2 HEAD

sydra Thanks a lot. Do you think you could make a pull request on my github repository? I've started upgrading, but it's a bit of a hassle because the kernel suddenly changed, and I had to revise a few things (with Libreelec 13 I'll have to revise a few things, because it's becoming difficult to maintain everything). Maybe we can join forces.

Varo95 unfortunately, you're unlucky; that chip isn't well-supported. Introducing the 4.4 kernel into my builds requires a lot of work, and it's unlikely to work because Kodi uses the mainline kernel's hardware decoding support, which is different from the 4.4 kernel's. As for USB Wi-Fi devices, I've never encountered one that didn't work (almost all work with new kernels, or at least there's a driver I could include). They also work better than integrated Wi-Fi because:

- integrated chip drivers are often soft-mac, meaning the CPU handles channel encryption, which overloads the board.
- antennas are practically non-existent, so reception is poor.

sergio.damian.galvan analog video output isn't implemented at the moment, and I don't know if it ever will be. The driver isn't difficult to make, but I'm personally short on free time.

finotti It's strange, the 6051p driver is the most tested and widely used (almost all my boards have it). I need a complete log (I haven't opened it, but I think you only attached the Kodi one). You can find the information on how to do this in the first post.

Tsxop But is the green screen only when playing the video or always? It could be a bug in the HW decoder pipeline, Kodi or worse a 4K format nn supported via HW. Do other resolutions work?

marnal What do you mean "won't boot", black screen, or something else? If I understand correctly, you tried the test builds first(wich works) and then the "official" development builds.

As for the boot part, it shouldn't have changed much from 12.2. However, patches and kernel configurations have. As for the UART, it's often visible if you open the device.

hi, 4k problem is in the start of system the image jumps and tends to green as if it were an unsupported resolution, then once kodi starts it works fine.....for the no response it was not directed directly to you I thought someone else could answer too, we all work it's just a hobby of course, thanks

ciao,

all 322x SoCs support 4K. Depending on the type of DDR installed (DDR2 or DDR3), you may experience performance degradation (DDR3 is faster and therefore plays 4K streams smoothly compared to DDR2). Your box is a new model for me, and while I've learned over time that the design is fundamentally similar to all boxes (the generic DTS boot 99.9% of the time), there may be some small differences. So besides trying another cable (if I'm not mistaken there are specific ones for 4k), I'd need a log (you'll find how in the first post), to know if you're using the generic DTS or one of the supported ones, and possibly a link to the original firmware (or alternatively a dump of your emmc, or even better, a dump of the first 128MB of your eMMC) so I can extract the stock firmware DTS.

Grazie

matheusdanoite sorry for the absence, but I'm updating my build to Libreelec 12.2, where some changes forced me to revise all my patches. As soon as I'm done, I'll try installing and getting your driver working.

matheusdanoite i've never seen your board, but thanks for pointing me to the thread, I'll give it a try.
I also wanted to ask you for your box model because from the logs I saw that you're using the generic configuration (probably because yours isn't listed in the supported models). Maybe I can add your box.

@matheusdanoite in your case, I need to try to figure out if there is a driver that can be used. I remember seeing something here on the forum, but I don't remember where.

not any answer ...

Like those working on the Libreelec project, I'm a volunteer who dedicates part of my free time to something I enjoy, and I'm not paid to do it. The project isn't dead (I recently purchased the beloved/hated HongTop H20, and some users want to donate boxes to support my work). But precisely because I dedicate my free time to it, I obviously have little of it these days/months.

Quote from ochentay4

is there ANY way to write this or any other build to a NAND, without using multitool? my MXQ-4K doesnt boot it, yet it boots LibreElec without issue.

Unfortunately, as stated in the first post, NAND is not supported because the driver found in the bsp rockchip kernel is obfuscated and does not compile with new kernels.

Tsurugi as for the wifi, I have to port some drivers from libreelec 11. Instead, for the 4k problem, please explain better. Are you having problems with playback or with the Kodi GUI?

So Wuk-jvi , if you want to compile a version that works, these are the generic instructions, change this script https://github.com/LibreELEC/Libr…r#L347C1-L350C9 adding the flag I indicated earlier and run the build as shown here

But keep in mind that performance will never be the same as the original board because the RAM is slower. The problem with LibreElec is relative, but it's worth mentioning.

chewitt the truth is that while Rockchip's upstream support is decent, for RAM management purposes, it's currently preferable to use the proprietary binary (rkbin miniloader). Libreelec supports this type of bootloader where tpl/spl are proprietary and the uboot proper upstream is used.

I don't use this board daily. I bought it to help with support, but I solved the problem by adding that flag.

You have the same problem as me. As described here, unfortunately a fake version of the board is being sold (I can't tell you if it's due to Radxa or the distributor). In fact, some voltage regulators are missing (I presume) and the RAM is different. Rockchip's proprietary bootloader recognizes them and in fact, from the serial port output, the clock set in the distro that works(dietpi) is 666MHz. The Libreelec bootloader (which is the upstream one) for this board sets it to 800MHz as it should be if everything were according to the official specifications.

Unfortunately, this board doesn't work at this frequency. There's no solution at the moment, or at least the legacy bootloader should be used in Libreelec as well.

hi FurmanSK , after months of waiting (my fault, I didn't have time available) finally thanks to chewitt, the support for the ddr4 ram mounted on the roc-cc has been released. Now this board has an optimal official support.

Wuk-jvi please share pic of the board.. unfortunately radxa is unreliable because with the same revision of this board it mounts different rams that are not compatible with the uboot currently used in libreelec. unfortunately it happened to me too. the only solution if this is the problem is to go back to the proprietary bootloader

Samui67 you can use dd to take only the first 100 MB for example like this

dd if=unpacked.img of=first_100_mb.img bs=1M count=100

Quote from Samui67

Confirmed. The USB port on the HDMI side - if it is connected with my PC - is showing the SSD (4TB) correctly and it is read/write accessible. But it is not detected as drive in LibreELEC!

Could you send me a dmesg of libreelec? What filesystem is the hard disk formatted with?

Samui67 thanks for the info..

I try to buy it from alibaba, hoping the model with rk322x arrives and not, as for the android boxes, something else. If you can share the first 100mb of your dump I will try to extract dts.

however given the type of device, it does not recognize the sata hard disk or can you not use it connected to a pc? I ask this because it's possible to configure the kernel to transform the usb ports into usb gadgets and therefore make, for example, an android box similar to an external hard disk that you can connect to a pc. This feature is disabled because I always thought it was not very useful (until today).

Hi Samui67, as far as i remember, the rk322x does not have a sata controller nor a usb3 controller (i'm looking at the case of the device).
Probably there is a USB to SATA controller that is connected directly to a USB 2.0 port (in many devices there are 4 ports and here i only see 3). In any case, this device is fascinating. Where did you buy it? To try to solve your problem, I would need some LibreELEC logs and probably also the DTS of the original firmware (is it an Android?).
