17:56:25Posterdatithen why I cannot access /sys/class/gpio/gpioXX directories?
17:56:42PosterdatiI've got the right udev rules running
18:04:29jackdanielPosterdati: there must be something wrong with permissions. ecl works as any other program inheriting uid and gid from the invoking user.
18:04:45jackdanielmaybe you haven't log out and log in back after adding udev rules?
18:05:34pjbAll I know is that ccl cannot read "files" in /proc as normal files, (using read-sequence) and that I had to use read-line instead. cf. com.informatimago.common-lisp.cesarum.stream:contents-from-stream
18:25:11Posterdatijackdaniel: the problem seems to be that when I export the gpio, writing to /sys/class/gpio/export with a common lisp function, the /sys/class/gpio/gpioXX is created with the correct permissions, but
18:26:37Posterdatiif I wait after exporting that the /sys/class/gpio/gpioXX becomes group readable/writable it waits forever
