  1. @KSilva That does not look at all the serial output of the board, but rather some Windows log of some sort. You are definitely not reading the board serial output correctly.
  2. In fact instructions in no case tell to erase flash when you use multitool. In case of NAND chip (and multitool clearly tells you when the board is equipped with NAND), you must use steP-nand, as stated per instructions
  3. Bad thing: you tried something that was totally not suited for your board. If your board still boots, please don't try it again or you overwrite the bootloader. The update will come via regular apt upgrade when Armbian team will rebuild the APT packages (I don't know the date, maybe it already happened...)
  4. Hello. That's for boards with NAND, eMMC users don't need that. What flash memory do you have?
  5. I took a look to the DTB of the firmware and the OTG port is enabled in both u-boot and in Android linux kernel. This does not mean that is effectively wired to any physical port though, but there are good chances it is. Anyway I also installed the firmware of your board on a board of mine, it boots and works flawlessy. I was able to enter loader mode just pressing the reset microbutton and plugging the USB male-to-male cable in the OTG port. From there, rkdeveloptool was able to discover the board and potentially I could follow the procedure on the first page. Now I ha
  6. Shorting the board, as long as you have the pins exposed, should be pretty simple. Use a cross or flat small screwdriver over the exposed pads nearby the eMMC chip: even those pads are unpopulated, usually they are still connected to the electric traces. Be careful to find the correct orientation of the chip to find the two pads to short. To be honest, some people also say that the 7th and 8th pads should be tried from any edge, because orientation may change. On my boards the working pads are always 7th and 8th starting from the same edge of the circle marking but on the opposite side. Y
  7. Hello, there is a section in the first page for your case: no sd card slot + eMMC. You don't need the USB stick and the multitool (that's for people with NAND). You need an USB male-to-male cable and rkdeveloptool to burn directly the image on the eMMC.
  8. Keeping android on emmc is not supported because requires some additional steps and a different bootloader arrangement.
  9. Very cool product, 3568 in action
  10. There is definitely something wrong with your board, and indeed this looks like an instability caused by some hardware fault or misconfiguration. Of course I suggest you to exclude the wifi because it is the most probable offender, so don't use it and blacklist the module too to avoid any possible interference. Then limit the cpu frequency to 1.2Ghz: as I already said 1.2Ghz is the rated frequency for rk3228a; 1.3Ghz is overclocking. Of course you can have hardware problems everywere: the board may be faulty, the RAM may be faulty, the NAND may be faulty, etc... the stack dump d
  11. It looks like nothing more than scrapped orange pi's with another name and the ancient H3 SoC. I would not buy it.
  12. Never had such problem. I have a box with buster minimal kernel 4.4 attached in LAN and I have no reachability problems (ping, but ssh and samba too). It is always there and always answers promptly, even if I leave it alone for hours. I installed openmediavault and various other services on it, so don't know if some tunables have been changed, but for sure I did not change any parameter from stock. Still I use it with LAN cable, which way more reliable than wifi by far.
  13. Hello @gurzixo, most of your observations are true, I will add some precisations to make things more clear as long as I see you like having things tidied up The box is surely intended by rockchip to run under Android, but tools are definitely OS-agnostic. Also the tools given by rockchip are intended also for other SoCs that are publicized and sold and supported for use in Linux (like rk3288, rk3399 and rk3328). Not exactly. Armbian is a set of scripts and patches that allows building Debian-based (so Debian, but also Ubuntu) images capable to boot on several ARM
  14. rk322x-config sets the maximum cpu frequency to 1.2Ghz in case you have an rk3228a because it is their rated speed. Maybe your board has a rk3228a but you choose rk3228b or rk3229. About wifi performance, it is perfectly normal that TX and RX performance differs. Usually TX is a bit higher than RX, but that depends a lot on the setup and the connected devices. If a process is using more than 100% of the cpu (I guess you mean using top or htop) it means that the process is using more than one core. This is perfectly normal although. The only issue with legacy 4.4 kernel is the lo
