  1. If you're doing a simple copy (with Thunar, Nautilus, Dolphin or the simple cp command) there's no synchronisation mechanism, so it's either Replace All or Skip All, meaning it will replace every file present at the destination, or skip the copy of any file being present at the destination, regardless of its other attributes. What you're looking for is a synchronisation software, like 'rsync'. Though, you should try your hands with this software using a few dummy folders, since synchronisation softwares can be complex. Rsync allow you to synchronise two folders, with options like "copy the files not present", or "only replace files that are more recent", ... And can also do that through the network.
  2. Well, to add the "Virtual Framebuffer" driver, you'll have to reconfigure and recompile the Linux kernel using the armbian build tools, and ensure that CONFIG_FB_VIRTUAL is set to 'y (* compiled within the kernel)' or 'm' (compiled as a loadable module) when configuring the kernel... If you're not familiar with these tools, and you have no idea what "recompiling a kernel" means, the $3 Dummy HDMI plug might be WAY better for the time being. Even more due to the fact that I'm not sure that it will solve TeamViewer problem entirely. I just think so, since the virtual framebuffer can be used for "off-screen rendering purposes", so TeamViewer should be able to use it to read/write pictures into the framebuffer, and then send it through the network... Edit : Yes, you'll need to follow the guide you mentioned, if you want to reconfigure and recompile a custom kernel for your board.
  3. Note that the serial console clock changes to 1500000n8 when it boots, so be sure that the serial console receiver also reads at that speed, else you might not see any log after booting.
  4. I guess that you could always try to recompile your kernel and enable the "Virtual Framebuffer" driver ( CONFIG_FB_VIRTUAL=y ) and see how it goes. This should create a virtual /dev/fbX node... If you don't plug your monitor on startup, this one should be /dev/fb0 . Else, you'll have to play with udev to either force vfb to /dev/fb0 or the rockchip driver to /dev/fb1.
  5. Is it possible to get the patched .dts file at least ? This way, we could create a patch and integrate it to the armbian build tree.
  6. Here's the (very late) pull request :
  7. Here's the patch : While the kernel drivers doesn't generate any BUG now, the connection still fails in one way or another, since hostapd appears to be unable to setup wlan0 correctly. Or maybe it's just my hostapd.conf that's badly setup... Give it a try and tell me how it goes. From 48646460655b36cb616c7ad05f66f63631bfe1d8 Mon Sep 17 00:00:00 2001 From: "Miouyouyou (Myy)" <> Date: Fri, 14 Aug 2020 09:27:49 +0200 Subject: [PATCH] drivers: staging: rtl8723bs: Initialize structures correctly This avoids a BUG when freeing the ressources in nl80211_send_station .

  8. Ok, that clearly seems to be a badly initialized structure issue. Changing struct station_info sinfo; by struct station_info sinfo = {0}; in drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c : rtw_cfg80211_indicate_sta_assoc remove the BUG calls on a client connection. Now, I'll have to test it in a real environment, to check if the Wifi connection works and is stable. I'll post a clean patch tomorrow.
  9. I'm trying to understand the issue, but it seems rather bizarre. Basically, when freeing the station_info structure in nl80211_send_station, kfree is called with a somewhat valid pointer, but then kfree (SLUB version) trips when calling PageCompound on the page of the provided pointer. My best bet is that the structure isn't initialized correctly, leading some fields to be initialized with garbage values. However, it seems strange that everything goes without any bug until that specific point.
  10. Just tried it today, but without network though. It boots correctly. There's no desktop, obviously, since it's a minimal image. But I was able to log-in as root, add a user, reboot a few times and log-in as the user. Could you tell us what's happening actually ? No Tinkerboard led ? Stays red without any activity ? It boots without HDMI ? An error message appears ?
  11. Thanks for testing ! I guess we can include this patch in the next release, then.
  12. It seems to be the same issue as : I'll try to investigate this, see if the patch provided there works nicely. Also, does this problem happens every time you run in AP mode ?
  13. Sooo, I tried to fix the issue, using a 5.8-rc3 kernel... While the frequencies are back, there's some heavy glitches with Panfrost drivers and I don't know if that's due to kernel changes (entirely plausible) or if that's due to the patch. I'll try test a 5.8-rc3 kernel without this patch, just to check who's the culprit. Meanwhile, here's a patch that brings 500Mhz frequencies back for Mali GPU on RK3288 boards : From 73258d32daf3a661281bb5c77c5e2e06c7ff714e Mon Sep 17 00:00:00 2001 From: "Miouyouyou (Myy)" <> Date: Fri, 3 Jul 2020 02:02:18 +0200 Subject: [PATCH] arm: dtsi: rk3288: add GPU 500 Mhz OPP again Undoing the very bizarre mainline kernel patch, 75481833c6dbab4c29d15452f6b4337c16f5407b which main purpose is to sync some 3.14 kernels hacks to mainline kernels, for reasons that only matter for a few Chromebooks, and shove it down the throat of every RK3288 user. If you need to avoid the GPU going to 500 Mhz on Chromebooks, remove the OPP entry inside the DTS that actually matters to RK3288 Chromebooks. Meanwhile, the 600 Mhz operating point can prove to be unstable on some RK3288 boards, while 500 Mhz works fine.

  14. Somebody had some issues with a few screens on X11, when testing the latest DRM patches to improve HDMI handling of various screens, and were able to force X11 to use manually input EDID values. If you could retrieve the EDID values used by the TinkerOS and feed them to X11, you might be able to get this resolution working... Though, that's a weird bug. I might have to reintroduce a way to get the list of EDID values obtained and evaluated by the DRM driver, for each plugged screen, in the dmesg logs.
