  1. The image is Armbian Bionic desktop legacy kernel 4.4.y Armbian_20.02.11_Rockpi-4b_bionic_legacy_4.4.213_desktop.img
  2. Hello all, After some time without touching it, I came back to my Rockpi 4B. I installed the latest armbian bionic image on a samsung 64Go card. All seems to work fine for the first boot. But when I try to restart the system I don't get any display on screen. To get it back I need to unplug HDMI plug and re-plug it. Didn't found any conversation about that trouble? Is it a bug or is there something I can do to fix it ? Thanks for your answers. Pat
  3. Hello all, After having done the mod suggested by Martin I have now a wifi used as hotspot which is stable. But the signal is really, really weak. So when I am more than 5m from it my PC doesn't catch the signal which is something like 25% of the full scale. Is there something I can do ?
  4. @martinayotte Your mods works fine but only to connect to a network. But the wifi is really unstable when used as hotspot. Hope it will improve a bit in the future with new firmwares. ping PING ( 56(84) bytes of data. 64 bytes from icmp_seq=1 ttl=64 time=1970 ms 64 bytes from icmp_seq=2 ttl=64 time=948 ms 64 bytes from icmp_seq=3 ttl=64 time=91.1 ms 64 bytes from icmp_seq=4 ttl=64 time=118 ms 64 bytes from icmp_seq=5 ttl=64 time=4.38 ms 64 bytes from 172.
  5. Obviously the problem comes from the Armbian image. I tested the Radxa Ubuntu server and with it the wifi is functional. Maybe I have to do the same as you have done, compile a kernel on my side. What type of platform do you specify Rockpro64 ?
  6. So, what's the blip ? What kernel do you use Martin ?

  8. Hello all, I have just got a all new Rockpi 4B. I have installed the armbian image and xfce desktop. I just have a problem, the wireless device is not available. hwinfo --short gives the following result. I guess that broadcom is the wifi device but looks not to be recognized by the armbian image. Am I right ?
  9. Hello, After having done the mods I have compiled all successfully. And tadaam, now all works fine. I finally have user access to the GPIO. A very great thank to all of you guys. Hope those patches will be part of the official release of ARMbian. Best regards Patrick
  10. Sorry Tony, but as I haven't got answers about my question that is why I asked it again. If I have been able to do it by myself I would have. But unfortunately I don't have the knowledge to do it. I thank you for the help you provide to all the linux users community of this board.
  11. Back with my problem of gpiomem public access. Does anybody can help ?
  12. Hello Is there a support to access to GPIO for anybody (/dev/gpiomem) like on RPI3 ? Someone suggested me to use it. But I am too much awkward to create from scratch a kernel that include it. Thanks
  13. Hello all, I have initiated this project months ago : I had on previous version of Armbian (5.32) solved (partially) the wifi instability. Today with new version whatever I do, the wifi remain instable. Furthermore I tried to drive a focuser directly from the GPIO extension port. But I can't use it because of a leak of privileges. To make it work I need the /dev/gpiomem public access. I saw that it might be implemented in the last version of TinkerOS (2.0x). Will it be implemented in Armbian next versions ? Because of t
