SecureXperts Posted May 16, 2019 Share Posted May 16, 2019 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?

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 Link to comment Share on other sites More sharing options...

But I presume that GPIO14/15 are not at /dev/serial0 or /dev/ttyAMA0, but maybe some thing like /dev/ttyS1 . Link to comment Share on other sites More sharing options...
