  1. thanks, will try it out and upload serial logs after i solder the wires on it. got a bit distracted since i'm currently cleaning up the other box from junk and trying to reflash and reinstall pihole.
  2. hello, i got a new rk3328/3318 box and it is an MX10 box. board is MXQ-RK3328-D4_A ver: 2.0 date:20181219. i was wondering if anyone has the same board as mine and got armbian running on it. here are pics of the board. https://photos.app.goo.gl/ikSCNH7s59f2v5EE7 if serial logs are needed i can solder some wires to gather the info. thanks.
  3. works like a dream @jock. here's my freshly installed/updated hk1 max box dmesg using latest libreelec hdmi patched 6.3.13 kernel. i hope mainline gets around to updating hdmi timing stuff. brcm 6334 2.4G and 5G works out of the box. using it currently as pi hole box. for those having problems with rtl 2734c (rtl8237cs). wireless module that gets detected but cannot connect to AP, here's a reuploaded nvram you can try out (no guarantees though), it solved my problem way back with the rounded h96 max i am using as klipper host. file is not mine, credits to the original uploader. dmesg.log nvram_2734c.txt
  4. @FatalWorld there is a kernel oops about swapper being tainted. your board is the same as mine albeit with different wifi chip. these are the things i would try if that was my board: 1. backup original firmware and try flashing different firmwares on the emmc chip from the github page. 2. if running from sd card, i would try a different sd card just to test filesystem stability. 3. i would also try ram testing. 4. upload logs for different test image used. just do a "dmesg >> dmesg519.log", download that log using winscp and include it in your next post, it would help jock and others with debugging where your problem is coming from. got mine solved that way. cheers and good luck!
  5. please indicate box type and board version, if posible attach top and bottom images of the board.
  6. board version? sometimes those 4 pads do not work for me, what i sometimes do when i'm feeling lazy is i try connecting the ground on the board first then i try connecting the rx pin of usb serial to different pads of the board while booting to find its tx pin. you only need two pins to capture serial debug logs. i found mine at the back of the board. i think i posted the pics in this post at page 26. you get very low chances of bricking your board if you do it this way. other method i use is a low cost stm32 o-scope and a multitester which a is way safer method in my opinion.
  7. very strange indeed. i was testing it on a uhd 55" samsung tv that has not been updated for about 2 years, it is plugged in to hdmi ARC port, so that maybe the source of my confusion too. the reason why i bought the same board as yours is to see if they would all behave the same way and indeed they have. i really need to start learning how to compile the kernel for these boxes, i do have experience compiling kernels for linux desktop and server but that was way back when 2.6 was bleeding edge.. dmesg-rk3328yx.log
  8. hello everyone. i just got an hk1 max with yx_rk3328-v1.0 board and tested it with 5.15 kernel and 5.19 images. HDMI works great on 5.15 out of the box, 5.19 on the other hand has no hdmi display. kernel 5.19 with the libreelec patch has hdmi display out of the box.
  9. hello. 5.19.15 kernel works both on rounded and square h96 max box v1.4 boards and so far they are both running stable with hdmi display for about 6 hours now. attached are the dmesg logs for both boxes. for the square box, i did a fresh install of @jock's full image and for the rounded one, i have installed the new kernel and dtb. i2cdetect -l needed sudo and the output is the same as @MattWestB's. dmesg-square.log dmesg-rounded.log
  10. @jock awesome! it worked like a charm, unfortunately i was not able to upload a dmesg log. will upload it tomorrow after i test it on the rounded one too. it runs at 1.3GHz and 76-83 degrees celcius and is very usable as minimal desktop, it even has compositing enabled, with a little bit of active cooling and a better case with more ventilation, it can be nice mini workstation. usb is also stable for both usb2 and usb3, i tested it with usb3 hub and plugged in 4 devices(printer, keyboard, mouse and a usb microscope) and they all worked fine.
  11. @jock good news! i tested you edge build of 5.19 kernel and dtb and it booted great with hdmi output on the squared h96 max v1.4 board. i reckon it would work flawlessly on the rounded one too. sorry for the crappy image quality i tested this at work.
  12. @jock the hdmi does not work on both rounded and squared one with 5.19 kernel. date markings are exactly the same "2020/06/29" as well as board version rk3318_v1.4 on both boards. the board version was under the heatsink, i just used my phone's flashlight to see and read the board version. also out of curiousity i opened up my dead tylex v88 mini board and the external crystal is 26MHz and uses a 3R3 inductor, seems the SPxxxx wifi chips all need external crystal and inductors. @MattWestB i do not know if i2c is used for communication with hdmi but both boards do behave the same, the both have hdmi output on 5.15 and both have no output on 5.19, the components around the hdmi looks exactly the same but i will take better pictures tonight when i get back home from work.
  13. hello again. @jocki'll be taking pics of both boards tonight and extracting the dtb's. some vendors do give clues as to what wifi chip is placed on the board. my squared h96 max v1.4 board works fine on 2.4GHz and 5GHz and works on default distro of the 5.15 kernel build including hdmi, hdmi does not work on the 5.19 kernel though. my rounded one which i will disassemble seems to have the same board but has no 8 segment lcd. it works almost the same as the squared one with the exception of the nvram that needs replacing. edit: i seem to have identical boards for the rounded one and the square one, both are rk3318 v1.4 dated 2020/06/29. differences are square and rounded respectively. wifi chip: fx8934, sp2734c crystal beside wifi chip: none, 37.4MHz inductor beside wifi chip: none, 4R7 fd6551 and 8 segment: yes, no square pics:https://photos.app.goo.gl/U5LEJrav5FZMh6LEA rounded pics: https://photos.app.goo.gl/dUBqpmVfWpshq4PV9 i think @fabiobassa can chime in on the hardware part because it seems we can put in an fd6551 and an 8 segment on the rounded h96 max box easily and make openvfd work on it too. i also think we can transplant a similar but better wifi chip on it if ever we have those on hand.
  14. there seems to be 2 types of h96 max on the market, one is the more rounded and smaller case which has an rk3318 and 2734c chip that is working only on 2.4GHz and the other one has a bigger case with square corners which has real 4334 wifi chip and supports both 2.4GHz and 5GHz bands. Some square box with lower specs for storage 2GB ram +16GB has 2734c but 4GB+32GB almost always has real 4334 chip. i bought both. the square one is about $3 more expensive than the rounded one. my square h96 max seems to have real rk3328 (verified by using hexdump) and am testing xfce 5.15 version at the moment, hdmi sound doesn't seem to work though. but overall stable at 1.3GHz with a little bit of active cooling. anyways, if you're gonna play with boxes like this, make sure you have an extra cable to the router ready always. my setup includes an always ready rig for uart, usb male to male, ethernet cable and 5v supply ready for quick hookup. the rounded one i have is currently running my 3d printer and will not be updated anytime soon. i'm planning on getting an hk1 max as that is @jock's testing platform, i hope i get lucky and get the same specs.
