@Jaisere the rootfs i gave to you clear says " utgard armsoc" DON'T UPGRADE DON'T DO NOTHING or you will loose the optimization made by linaro team the chromium browser itself uses a sort of hardware acceleration, the video uses a sort of gpu.. but DON'T EXPECT too much For nice graphical environmetn follow @jock 's suggestion, but will loose NAND

@Jaisere the problem ISN' T the lima or xorg issue, but "VERY SIMPLE" : it doesn't find the rootfs. it is clearly explained in your log : WAITING FOR ROOT FILE SYSTEM This indeed happen because when you update and upgrade maybe it takes a NEW KERNEl and new kernels DON'T support nand . That's all!! No lima issues , no mesa issues, no other than newer kernels not recognize NAND if you want desktop environment and at same time install in internal flash try to find a 4.4.xxx kernel with xfce or lxde already installed Or you can try this rootfs but you still have to use a 4.4.xxx kernel https://drive.google.com/file/d/1jmtwGs88iXfCs7UtaEv1d5h7C9-9KGFg/view?usp=drive_link

@ktolisgr Nand Is ONLY supported on Legacy kernel Stay on 4.x.x and everything will work. This Is clear said in first posts and throught the whole 3ad but i know.....Reading Is boring and forum huge, better direct ask thing already explained billion times !

@djoness Welcome to the forum, italian HAM here. I also manager to install hblink and hdswitch in a rk322x . If you dont mind i will drop you some Infos in you private message, Just to let clean the forum for hardware and firmware related questions

@s-2 hello welcome on this thread, and unfornutately is a huge one with sone really interesting pages and some other less. but go staight to answers The first one isn' t a rk322x but a "CPU: rk3128" and thus you'll not find anything interesting on this thread , go search for 3128 (if any) The second is splitting out errors due to incorrect ddrbin ( let' s call it bios...) and you must go in maskrom to correct the problem by shorting pins on the board ( i haven't one so ignore which ones) Surely @jock will share this answer

Please Just remain focuses on rk322x and their problems. Dont go off topic Thank you all very much for understanding , highly appreciated

@Bert Kortenbach not at all On this same forum we had people that bought for sure amlogic 905 and got rockchip and vice versa. Is Total roulette with china vendors Where you located if you dont mind I ask

@Bert Kortenbach let Say 6/7 Pages back. Read them all

@Bert Kortenbach Bert if you go back in the history 3ad you Will find that some people also experienced no HDMI and @jock gave them the trght solution

Good job @NiTr0

@NiTr0 armbian has uart Speed at 115200 Original ddrbin at 1500000 I think you already switched to 115200 Other than this It hangs After trust loadingvthatbis quite strange Let see also @jock opinion

@NiTr0 Thanks you forvthose usefull Infos. Aldo a uart log when booting could be interesting

Yes Matt i remember very well so you help Is VERY appreciated. I was refereing ti follow exactly the steps jock Is asking Just for a while so after he can improve forUbuntu too

@MattWestB this effoRT @jock Is doing Is VERY specific to a new board calle r29 with ecmp . Please for the moment do not mix up things and Just follow EXACTLY what jock Is asking

@Jumperbillijumper from that link It seems t'ha t you already adked the same quesion in that thread and jock ( the same jock that is the author of all this stuff ) aleady answered there. Please do not cross posting , thanks so much

@Jumperbillijumper hello h20 is commercial name of this box it means nothing ! Can you give more infos, maybe open the box e grab some photos ? Anyway are you sure it is a rockchip platform ?

@Benedito Portela https://opensource.rock-chips.com/wiki_Boot_option Again ...here It Is Post scriptum: Also we started from few infos captured here and there on the internet to assembly the whole picture and , when It didn t work , It was a hard, boring, tired work of trials and errors. AGAIN : we dont own any of the new boards and NOBODY and repeat NOBODY even imagined to buy one for us to study. So you and others are very welcome to study as we did by trials and errors and report here any success Thank you for your apport

@Benedito Portela In this same whole 3ad the boot process of RK 322x Is explained plenty of times, with links to the original pages of rockchip too. Now... I understand that is a huge duty read all posts but... Did you ready It ?

@Benedito Portela Upload were Is more confirtable for you, even Google drive and Just share link Thank you

@Benedito Portela Did you backup the original android rom? Can you upload It somewhere? @ilmich Maybe in the originale dtb we can find some usefull info

dear friends i remark that we continue to give help to someone that is not willing to listen and perhaps THIS IS FRUSTRATING and not the fact that the box is not booting After discovered that IF ONLY HE had followed all the instructions that very kindly the users of this 3ad suggested instead of trying other magic combinations, and after we already said thet we need uart logs and so now I would like remember we said to him to stay on legacy kenel that is 4.4.xxx And guess !! He flahsed Armbian_22.11.1_Rk322x-box_jammy_current_5.15.80_xfce_desktop.img.xz in other words a 5.15.80 kernel Do we need other words?

@RaptorSDS I think that you said It in the best possible way. A so huge 3ad Is boring, i understand that is easier to drop in here and simply ASK !! But a community Is not working this way, also because in 69 Pages Is already contemplate every single info for error debugging, and even more ! And even if box still not working Is clearly explained what TRY TO INVESTIGATE Thanks you so much raptorsds for helping

@ego worker Just phisically have the board in our hands !!!! This Is the best hint we can give About the tutorial, this 3ad Is a big tutorial. Here you can find infos on boot process, logs, other bugs we found ( DDR timing, trust, other, cec) Just go with trials and errors as we already have done or donate a sample for the purpose

DISCLAIMER We don't own , have studied , have even seen ANY of the new mxq_r2b_lp3_v2.62_220225 boards We don't know what is going on those, no further help, infos, tips avaible until we get one of PLEASE STOP asking why they don't work because WE SIMPLY DON'T KNOW Any of you can still donate one sample for further investigations Thanks for understanding it !!!!

@n3o migh tI ask you how much skill have you not only on linux but in general on pc's ? What EXACTLY you mean by this ?
