  1. No,I don't care about legacy kernel,I posted it is 5.10.y in my blog,and the title is 'orangepi4 mipi dsi'
  2. yes,you can got all info by view my blog https://imdrq.cn on pc
  3. Yes,after the lcd display ok,I drive the touch by FT5x06 in mainline
  4. It works on main line kernel 5.10.6,rk3399 can use that patch(author is not me) driver mipi dsi: https://patchwork.kernel.org/project/dri-devel/patch/95f16906d654057c912f089d286bd51856ee3bdf.1607892237.git.tommyhebb@gmail.com/
  5. hi,you can read this know how to write panel dts for kernel 5.x https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/display/rockchip/dw_mipi_dsi_rockchip.txt
  6. I tried a lot few days to driver a 3.5" TFT(the display ic is ST7701S,touch ic is FT5316) MIPI DSI color display panel on Orange Pi 4 with kernel 5.10.y . but I unexpected found it worked on linux 4.4 legacy kernel ( but I don't want use legacy kernel ),that below: But on kernel 5.x have some serious error in dmesg: [ 6.135383] rockchip-drm display-subsystem: bound ff940000.hdmi (ops dw_hdmi_rockchip_ops [rockchipdrm]) [ 6.136150] rockchip-drm display-subsystem: bound ff960000.mipi (ops dw_mipi_dsi_rockchip_ops [rockchipdrm]) [ 6.405472] dw-mipi-dsi-rockchip
  7. oh,this patch was out of date,and it is use of mainline.you can use the armbian's image latest
  8. Because default firmware include default mac, Please download the file and replace the default firmware file: /lib/firmware/brcm/BCM4345C5.hcd,then reboot
  9. Look like you install image and dtb correctly,but you edit armbianEnv.txt not correctly or put overlay-user files not correctly.(Oh,I see my previous post,I spell error,should 'sudo apt install bluez') Yes,this is not easy for simple user.I edit dts include bluetooth and not need add 'overlay-user',so: restore your armbianEnv.txt install following dtb files reboot And should see: root@orangepi4:~# dmesg |grep Blue [ 3.982085] Bluetooth: Core ver 2.22 [ 3.982126] Bluetooth: HCI device and connection manager initialized [ 3.982135] Bluetooth: HCI socket la
  10. Oh,my error,I add bluetooth by dts,bluetooth will auto finish on boot,so don't need install bluetooth by armbian-config(because armbian-config use brcm_patchram_plus,it conflicts with the dts way). so you need use armbian-config remove bluetooth,then 'apt install bluz',and reboot And can you show me 'sudo dmesg | grep Blue',I want to make sure that you have placed the file correctly
  11. Please back up your old files. There is Image and dtb and overlays and bt firmware. OrangePi4-Bluetooth-Mic.zip
  12. About the Orangepi 4 's bluetooth chip AP6256,I read hci how get bluetooth mac address from 'https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/bluetooth/btbcm.c',the origin firmware file /lib/firmware/brcm/BCM4345C5.hcd include default mac address '43:45:C5:00:1F:AC',it is cause driver mark it 'HCI_QUIRK_INVALID_BDADDR',so I use hex editer change the default mac to '43:45:C5:00:1F:CA',you can use this firmware file replace /lib/firmware/brcm/BCM4345C5.hcd and not need do 'btmgmt --index 0 public-addr 11:22:33:44:55:66' set bluetooth mac after boot. BCM4345C5
  13. @piter75 Maybe the mic need fix,I see the OrangePi_4_schematic_v1.3.pdf,I found MIC_IN1P not link to IN1P.It causes the recording to be abnormal. This is a dts overlay,I tested recording better,I am not sure it is correct(because orangepi4 include two mic,one from board,one from jack). mic-opi4.dts
  14. well,it useable with or without headless,so just do as you like
