Hi all, I need to compile a simple serial driver but I miss something. First of all the kernel-related files. uname -r returns 4.4.194 So I downloaded both kernel-linux-4.4-rk3399-debian10.zip and linux-4.4.194.tar.gs files from tinkerboard and kernel git sites. The compilation is run by: root@linaro-alip:/home/amtek/linux_customVCOM_103# more compile.sh #!/bin/bash make -C /lib/modules/`uname -r`/build M=$PWD and the Makefile contains: root@linaro-alip:/home/amtek/linux_customVCOM_103# more Makefile # # Makefile for the USB serial custom driver. # # Object file lists. obj-m := customvcom.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) M=$(PWD) clean: $(MAKE) -C $(KDIR) M=$(PWD) clean If I copy the kernel folder from zip files to /source/kernel/ folder I have: root@linaro-alip:/home/amtek/linux_customVCOM_103# ./compile.sh make: Entering directory '/source/kernel' make: *** No rule to make target 'FORCE', needed by '/config_data.gz'. Stop. make: Leaving directory '/source/kernel' Any idea?

Hi all, tinkerboard 1 and Linaro Stretch OS: root@tinkerboard:~# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 9.3 (stretch) Release: 9.3 Codename: stretch root@tinkerboard:~# chromium --version Chromium 63.0.3239.84 built on Debian 9.3, running on Debian 9.3 We developed a web page that plays a MP3 triggered by javascript command: new Audio('mp3/'+sound).play(); It happens that when we automatically launch the browser after the boot by a script, the sounds are not played - no errors in js console and dmesg output. When we launch the same script from a terminal (same user = linaro) the sounds are played! We don't understand why! I only see a slightly different process (the last one) related to chromium: NO PLAY root@tinkerboard:~# ps axu | grep chrom linaro 1253 4.9 3.6 543976 74340 ?

Hi all, Tinker2 with Linaro Debian buster 10. We need to avoid the keyring request on a 'svn update' run on the machine but from a remote shell. If I run the same command on a local shell I have no request and then no problem. How can i avoid the request? Thanks

Hi all, we are using a TinkerBoard with Android. Every time we connect a USB device, a window ask us to enable USB and this setting is not remembered after the next boot. Is there a way to disable this notification? Thanks

Hi all, I need to connect in the simplest mode a GPIO pin (as INPUT) to the contact of a relay (not the control pins of the replay) that connects the pin to the GND. Of course I'm using the internal pull-up resistor but I don't know the value of this one. Is it a problem to connect the pin directly to GND or better to use a resistor to limit? Value? Thanks a lot! Regards

Hi all, I need a low consumption state then I put the Tinker in sleep mode by the command: echo mem > /sys/power/state Now I wake up the board by a button soldered in pins near the video connector. It is working well but I'm looking for different pins on the header, just to avoid the soldering. Thanks!
