Problem in Raspbian, discussed in: https://github.com/raspberrypi/linux/issues/553
Does not occur in Pidora. Raspbian decided to extend the export operation to user space but the implementation is ugly - the write to /sys/class/gpio/export completes before the user-space logic modifies the created files, which can disrupt use of those files. "Wait a bit" can help, but is unsatisfactory because there is no reliable definition of how long "a bit" must be to be effective. The write to /sys/class/gpio/export should block until the user-space operation is complete. _______________________________________________ avrdude-dev mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/avrdude-dev
