@Vladimir Trondin Thank you for such detailled Infos, photos and logs I doubt sv6158 Will ever work due lack of driver 's sources but sure @jock Will answer about it

@Parth maybe is easier if you tell us what are your goal, for what purposes you want use this box Don't forget the overall total cpu power and amount of ram, we are speaking of a 12 dollars soc. What do you want from this box ?

@Parth Even 3128 is working quite well with linux just compile kernel with appropriate config and appropriate cpu platform Regarding the garbage on uart, remember the uart speed is unusual ( 1500000 NOT 115200 ) until it starts modified uboot that is 115200 so you have to take care of this note I am the one in this project that discovered the uart pins on mostly of 322x boards and I can give for sure that if garbage comes out is: wrong pin wrong speed lack of ground On the software - firmware side can give you answers @jock @RaptorSDS and all the friends athat daily work on those boards

@Parth

@hfrts hello First of all and following the @jock's answer and the general rule of thumb of this 3ad I suggest post some photos of board and even better uart logs for every board. Second are well known general problems with inside wifi chips Third when you say " performance is very limited....." are you referring to wifi performance or overall performance of the box? Performance of wifi is limited to 24/26 mbs since the internal chip often is just one chain tx/rx sock ( maximum is 54 but this speed is avaible on double chain socks ) If " performance is very limited....." is referred to overall performance of the box, well try consider its hardware specs and what is the purpose you use the box for @jock... "they are dirty cheap hardware..." .........that costed to you, me and all other friends hundred of sleepless nights LOL 😅

@bellad 6200 Is not 6051 neither 6052 or other Is Just 6200 !!! And even It loads ssv6051 module, the 6200 chip Is unsupported as @jock already said

@GSAR Are you sure the Quick up-down of Power didnt damage phisically the USB subsystem ?

@Blyato this is the other coin side of cheap tvboxes : devilish behaviour is just around the corner. If someone wants reasonable functions one must buy sbc well supported. That said unfortunately without original stock firmware, device tree or better the whole board in hands is quite impossible to guess what is going on Try to search on google or ask vendor for the stock firmware

@Blyato take photos with good resolution with and without shield please

@Hqnicolas no It Is NOT unexpected if you ONLY had read the whole topic It Is clearly exposed since the night of ages that nand works ONLY on legacy kernel. About compiling the new 22.04, you cloned rockchip64-legacy. Are you sure It would also work in 32 bit environment armhf such as rk322x?

@primoitt thanks for those Infos, even if not strictly hardware related , they are usefull for building new distros Could be also interesting open a specific thread related ti repositories issues and leave this for hardware specific

@suser your avatar is a smith cart about impedence, I suppose.. Italian HAM here This make me think that you have the right approach to problem : WHY IS NOT WORKING !!! And not the simple " ok it will work in othe manner" but " what hell is going now" This is the spirit that animated @jock @ilmich and myself when we approached to rk322x world Unfortunately lack of documentation = trial and errors and understand code and compilation !! And again unsuccess and again trial and errors. Even actually the evil nand driver is ONLY proprietary, even if jock and ilmich actively searching for months a workaround Welcome in the club 😅

@suser 8723 are pain in the a** On other boards we have had even 8723cs but ONLY working with 8723bs driver. And many other strange combinations My suggestion : IF wifi strictly needed buy a few dollars external USB wifi dongle. ask here which are the best supported

@R Tech Definetly not Easy tò answer what Is going wrong with no booting without any support from uart ( USB/ttl adapter). Let see if somebody else has experienced trouble with this board like your, very recent board Btw It has ecmp chip

@DarthMirous have you read the whole thread ? This problem has been already discussed, such as has been discussed that commercial names (MXQ 4k Pro 5G) have no meaning at all Go back at least , let's say , 10 pages starting from this searching for problems similar to yours , and also post photos of the board inside with particular attention to version of the board
