ASUS tinker board 2s, GPIO runtime error

[tangochuynam]

after installing asus gpio and I import ASUS.GPIO as GPIO, it shows this error RuntimeError: This module can only be run on a ASUS Pi!

[tangochuynam]

I check the py_gpio.c and found this error. // detect board revision and set up accordingly

if (get_asuspi_info(&asuspiinfo))
{
    PyErr_SetString(PyExc_RuntimeError, "This module can only be run on a ASUS Pi!");
    setup_error = 1;

check code in cpuinfo.c, this snippet code I don't understand it involves for older tinkerboard, maybe not work for tinker board2s if (!found) return -1; info->p1_revision = 3; strcpy(info->revision, revision); info->type = "Tinker Board"; info->processor = "ROCKCHIP3288"; info->manufacturer = "ASUS"; info->ram = "1024M";

I use the latest version(Debian-Buster-v2.0.0),The same problem is not fixed.

I think it'd be better to use /proc/device-tree/model for board identification instead of /proc/cpuinfo, whose display format is more likely to change.

I have "Tinker Board 2 Debian 10 V2.0.4" OS for the 2S board and the GPIO driver is not working either, is there any solution to make a simple led on/off test?

[JasonShiao]

As a workaround, you can simply modify the get_asuspi_info function in source/cpuinfo.c and make it return 0.

[dpergarc]

I have just tried that workaround, and despite the fact that it compiles and executes the script, the operation of switching on/off the led is not executed.

Hi @tangochuynam ,. @JasonShiao @dpergarc : The gpio python library of ASUS tinker board 2s(RK3399) preinstall in the image by default. Don't reinstall and compiler the source by the github because the github library is for Tinker Board S(rk3288). Please reference the related source path for Tinker board 2s in /usr/local/share/gpio_lib_python_rk3399/

Thank a lot!
