apport information
** Tags added: apport-collected impish
** Description changed:
The current versions of gpiod, libgpiod-dev and libgpiod2 (1.6.2-1) use
version 1 of the GPIO character device API. However, they cannot work
because the interface is disabled in the default kernel (tested with
5.13.19). After rebuilding the kernel with the option
CONFIG_GPIO_CDEV_V1=y, the gpiod tools work as expected.
What I expect to happen:
$ gpiodetect
gpiochip0 [0-003c] (8 lines)
$ gpioinfo
gpiochip0 - 8 lines:
line 0: unnamed unused output active-high
line 1: unnamed unused output active-high
line 2: unnamed unused output active-high
line 3: unnamed unused output active-high
line 4: unnamed unused output active-high
line 5: unnamed unused output active-high
line 6: unnamed unused input active-high
line 7: unnamed unused input active-high
$ gpioget gpiochip0 0
1
What actually happens:
$ gpiodetect
gpiochip0 [0-003c] (8 lines)
$ gpioinfo
gpioinfo: error creating line iterator: Invalid argument
$ gpioget gpiochip0 0
gpioget: error reading GPIO values: Invalid argument
$ cat /proc/version_signature
