Re: [avrdude-dev] [bug #44218] linuxgpio not working with raspberryPi 2. Can't open gpioX/direction : Permission denied. Fixed by little delay
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 avrdude-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avrdude-dev
[avrdude-dev] [bug #44248] trunk version doesn't work with ch340g in linux
URL: http://savannah.nongnu.org/bugs/?44248 Summary: trunk version doesn't work with ch340g in linux Project: AVR Downloader/UploaDEr Submitted by: None Submitted on: Sat 14 Feb 2015 04:56:30 PM UTC Category: None Severity: 3 - Normal Priority: 5 - Normal Item Group: None Status: None Privacy: Public Assigned to: None Originator Name: neeo Originator Email: n...@xl.wp.pl Open/Closed: Open Discussion Lock: Any ___ Details: There're lots of arduino clones using ch340g usb converter - which uses ch341 linux driver. However latest (newer than 6.0.1) avrdude doesn't get serial settings from these devices (with error Cannot get serial port settings). The function ser_setspeed tries to get settings using ioctl(fd-ifd, TIOCGSERIAL, ss) - unfortnatelly the ch341 (nor the ch34x from the chipset vendor) doesn't implement any ioctls. avrdude 6.0.1 (and older) doesn't do all the ifdef magic for different OS, and it works as expected. ___ Reply to this item at: http://savannah.nongnu.org/bugs/?44248 ___ Message sent via/by Savannah http://savannah.nongnu.org/ ___ avrdude-dev mailing list avrdude-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avrdude-dev
