  1. Hi I would need the GPIO 15 & 16 Serial Port at Physical Pin 8 and 10 referenced as /dev/serial0 or /dev/ttyAMA0 And here dmesg output dmesg | grep tty [ 0.000000] Kernel command line: earlyprintk root=UUID=bae26a9d-0ce2-427d-b5ad-fc7e7f9144e6 rootwait rootfstype=ext4 console=ttyS2,115200n8 console=tty1 panic=10 consoleblank=0 loglevel=1 ubootpart=6dc22fe6-01 usb-storage.quirks= cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory swapaccount=1 [ 0.001831] console [tty1] enabled [ 2.395963] ff180000.serial: ttyS0 at MMIO 0xff180000 (irq = 39, base_baud = 1500000) is a 16550A [ 2.396976] ff190000.serial: ttyS1 at MMIO 0xff190000 (irq = 40, base_baud = 1500000) is a 16550A [ 2.398003] ff690000.serial: ttyS2 at MMIO 0xff690000 (irq = 41, base_baud = 1500000) is a 16550A [ 2.398219] console [ttyS2] enabled [ 5.187164] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB0 [ 5.188446] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB1 [ 5.190296] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB2 [ 5.192186] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB3 [ 8.533335] ttyS2 - failed to request DMA [ 10.494551] usb 1-1.1: cp210x converter now attached to ttyUSB4 [ 10.542230] usb 1-1.3: FTDI USB Serial Device converter now attached to ttyUSB5 [ 17.112699] ttyS0 - failed to request DMA Thanks
  2. Hi I need to do the following things on my Tinker Board S what i normally do on Raspberry Pi 3: raspi-config; system; Hardware; 5 interfacing options, 6 Serial Would you like a login shell to be accessible over serial? = No Would you like the serial port hardware to be enabled? = Yes then I need to add the following line in the /boot/config.txt dtoverlay=rpi3-minuart-bt This activates the Serial Console on /dev/serial0 Where do I config Serial and how? what is the correct dtoverlay for the miniuar-bt in tinkerboard? does anyone have a hint for me?
  3. Hi martinayotte, thanks a lot for your input. Indeed i2c7 was not loaded. ;-) To add this overlay the good command is overlays=i2c7 without dash. Now all my HATs communicating over this bus is working like a charm!
  4. Hi pavelectric The /dev/i2c-2 is not available on my Image. Do in need to load some Kernel modules for that? Thanks
  5. The file is /boot/armbianEnv.txt and not in the /etc ;-)
  6. I have the following hat http://wiki.seeedstudio.com/Raspberry_Pi_Relay_Board_v1.0 my image detects the i2c interfaces and mounts them in /dev as i2c-0 i2c-1 i2c-3 i2c-4, I can scan the different i2c interfaces as folloging interface i2cdetect -y 1 root@rockpi:~# i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: UU 11 -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- I have set 0x20 address on my relay Board but cannot see the interface. Has anyone a hint what configuration settings i need to change Many Thanks Roman
  7. Its not just a hazzard of fire and forget... It's the missing differance of the Kernel Configuration coming from radxa.com and the Armbian RockPi4b Kernel config! ;-)
  8. Mabee we should change the Titel to "RockPi 4b Kernel Configuration suggestions"
  9. Today I comment my own post with the solution I have found: I propose to add these Kernel Configuration into the Actual development image It should work with 4.20.x and 5.x Kernels Please feel free to comment these additional Kernlel Parameters Have a nice Day Roman
  10. Hello, I would like to build my own Image. I have successfully build my img file and could flash it to my SDCard. When I boot the Image I have no Output on the HDMI port so I cannot even say if the Image is booting or not. There is also no IP address taken from my DHCP Server. How do i correct this two issues?
  11. Hello, I have several Hardware working with the Tinkerboard / S and like to propose those to the "Tested 3rd party hardware" section To whom can i address this? Thanks Roman
  12. Hello NicoD Yes indeed the Ubuntu Server image from radxa with SDCard is working fine…. it's just the Armbian
  13. Hello to all, I'm just impressed about your comments for my simple question… Many thanks to all who have brought ideas. +1 for Splitting this thread…
  14. Hello, I search the Documentation about LED and Its blinking status. My Board does not anymore boot, Green LED is on (not blinking) red LED is blinking regulary CPU gets very hot and no Screen output. I use the latest armbian image using the following link https://dl.armbian.com/rockpi-4b/Ubuntu_bionic_default_desktop.7z Does anyone have a hint for me Many Thanks Roman
  15. Hello, When I would like to start my PPP connection my Kernel says missing Module: I use the RockPi 4b with the Image https://dl.armbian.com/rockpi-4b/Ubuntu_bionic_dev_nightly.7z root@rockpi00001:/opt/LTE# pppd call gprs & root@rockpi00001:/opt/LTE# Couldn't open the /dev/ppp device: No such file or directory modprobe: FATAL: Module ppp_generic not found in directory /lib/modules/4.20.13-rockchip64 pppd: You need to create the /dev/ppp device node by executing the following command as root: mknod /dev/ppp c 108 I have created the mknod /dev/ppp c 108 but nothing changes in terms of Modules. Could you please add this module to the next build please? Many Thanks Roman
