![]() ![]() The UDEV rule might come in handy later, but this is sufficient for now! I chose the asterisk because I don't know if the 1420 number ever changes. solved it! Thank you! :) I tried this before, but apparently I was editing the Makefile of a different directory than the one I was trying to link and flash, so I thought changing it didn't have any effect. I don't fully understand the difference between tty and cu and not at all the difference between usb and wchusb, but I'm almost sure that the tty.usbserial-1420 worked before (and worked with the asterisk). Changing it to wchusbserial1420, either preceded by tty. dev lists tty.usbserial-1420, tty.wchusbserial1420, cu.usbserial-1420 and cu.wchusbserial1420 for the Arduino. The isp wires and vcc/gnd connected to the chip that I want to program. I understand that my writing wasn't clear enough: 10uF cap across reset/gnd. The filesystem where /home is located has to support Extended Attributes. Thanks for the replies! 10uF is the recommended value for an Arduino mega across it's reset and ground pin, but I tried other values too. #Inappropriate loctl for device unrarx how to#Any thoughts on how to fix this error? Attachment(s): I also attached my code and makefile (with. However, if I create a simple blink script inside the Arduino IDE and upload it using the IDE, it works flawlessly. I also tried programming an ATtiny13a chip, giving the same error. I tried quitting the Arduino IDE, Restarting my mac, 0.1uF and 1000uF cap, unplugging the programmer's usb cable and a different usb port. ![]() I installed Avrdude with Homebrew and also installed CrossPack. Now, since I think it uses Xcode, I moved it back to the applications folder on my mac. Maybe it has something to do with the fact that I moved Xcode to my external hdd, because I ran out of space. The expected result was a write to the chip, followed by a flashing LED (blink test code). It worked before, so I'm a little surprised. I'm using an Arduino Mega as programmer, with Arduino as ISP sketch flashed on it, 10uF cap across reset/gnd and isp wires and vcc/gnd connected to the chip that I want to program. Ioctl("TIOCMGET"): Inappropriate ioctl for device To then activate ACLs either remount the root volume (mount -o remount,acl /), or reboot the system (as the acl option is now in the options field for the root volume). #Inappropriate loctl for device unrarx install#I wanted to program an ATmega32A PU, but upon flashing (using make flash or make install in terminal), I get this error:Īvrdude: ser_open(): can't open device "/dev/tty.usbserial-1420": Resource busy What you have to do is to change your /etc/fstab file for the root volume to add the 'acl' option. ![]()
