@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 ?

@n3o

This board Is very well supported, It was the first I have investigated. It doesn t start because Is not founding the rootfs You MUST use any image with LEGACY KERNEL 4.4.XXX

@fangis I have a tx9 with allwinner cpu That is the reason i CONTINUE to claim that commercial names are fake. It would be so easy to put a male-male USB cable and look what PID and VID Is coming out

@art3mis_17 your board is ddr3 and nand storage NOT EMMC Is suggested go find a working sd adapter because you need stePnand method by multitool As alternate method you can try to flash android image on It. You can device device for sure but need some tools as a good sd

@ojogoperdi I am SURE you read the whole 3ad ( did you, isn't it ??? ) and I am SURE you and your team realized that multitool is based upon LEGACY kernel that is the MOST COMPATIBLE ever kernel tha t boots quite every box This said , I am also sure you and your team realized that saying TX9 box is a little bit as saying "water".. Sparkling ? Flat ? Cold? Warm ? Salty? With sugar ? TX9 means NOTHING is just a commercial brand !!!! It seems it is emmc from what you wrote and emmc are the easiest to boot since they don't mess with nand and FTL . To be sure it always boots from external sd is enough to erase the flash and it will boot form the stuff on the sd. I believe you already read this: https://opensource.rock-chips.com/wiki_Boot_option DDR2 ? DDR3? the ram is 1T or 2T ?? The only way to anser to a failing boot is attach a UART to the box I don't personally know this box so I cannot point you where rxd txd are on it, if present or just hiddend pads but I guess in your university you own an oscilloscope to further investigate where serial signals are About new kernels they should boot quite smoothly even from SD since the early stages of booting ( idbloader and trust or optee in his opensource version should be already in the right places) but missing uart log it is difficult to give you an answer As last resource we wait for a @jock 's answer regarding this behaviour but without serial log is a bit a nightmare Regards

@ojoperdi what do you mean by this sentence: If you would explain what is the final goal you want achieve by this boxes eventually would be easier find the right approach

@mcs Yes follow the link on 1st post This board Is very powerfull

@mcs You have nand and ddr3 Must use miltitool and stepNand with LEGACY image

@Luis mientras el espanol es un languaje muy agradable, ese forum es in ingles So please re-formulate your request in english and you will see that you'll achieve your goal Thank you

@EmilB beg pardon I realized you asked to boot from USB well the uboot is complicated, a bit refusing to boot straight from USB , sometimes uboot doesn't wake up correctly the usb and other devilish things But you can boot from internal kernel, dtb, init and then simpy passing the whole control to external rootfs I always do this when i want real hard disk spinning the os

@MattWestB this in not true Matt ! Infact the "hacked" multitool by emilb is booting and is booting from SD that IS AN EXTERNAL STORANGE !! and arranging the env or/and the commandline could even transfer to a real external usb drive all the process @EmilB indeed your board is a 3229 since efuse is quite hard to " hack and fake" and 3229 are really horse power. I guess you have maybe ddr3 would you upload a photo or take a look here , the post where ALL BEGAN, maybe you have same board. the aproach on this post is still based on repalcing internal parameters, we moved on zapping all and having a real gpt partition https://forum.armbian.com/topic/12401-long-story-linux-on-rk3229-rockchip/ But I guess you are " mixing up " too many things. What do you wanto to achieve ? Boot from external storage totally ?? ( very easy indeed) Install armbian on nand? ( remember that newer kernels are not gentle with nand) What is your purpose ?

@guitoscan Welcome in the club 🙃 rk322x are often " assembled" with the first avaible piece of chip laying around in producer factory. We have spent now more than 3 years reading of rkdevelootools android tools factory tools and so on and yet no clue with some boards we dont own

@Scmel Every One saying the problem Is elsewhere. Old..old game

@Himera no, we actually don't work on 3128 that is very very old comparing to 322x
