I enter the password once and the script passes it to the various commands. I spent two days on Scenario A and 3 hours on Scenario B.I'm using here-documents in a bash script to automate installation and setup where a password is required many times. The /dev/cu.usbmodem1421 was listed as a port option. Unplugged and replugged the USB cable into my arduino.I installed 'Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino version 1.6.8.In the IDE go to Tools-> Boards -> Boards Manager.Then I installed an updated board configuration from arduino and it worked! Testing on the first board I'd used under scenario A were successful as well. I repeated the steps in scenario A above but the problem remained. ![]() #INAPPROPRIATE LOCTL FOR DEVICE UNRARX DRIVERS#Checked the drivers and low and behold, the darned FTDI drivers had RETURNED!! It had been a while since Scenario A had occurred and since then I'd installed a few OS updates. ![]() There was only one Port listed in the IDE, dev/cu.Bluetooth-Incoming-Port. Ioctl("TIOCMGET"): Inappropriate ioctl for device Attempts to load sketches resulted in this lovely error: Using Port : /dev/cu.usbmodem1421Īvrdude: ser_open(): can't open device "/dev/cu.usbmodem1421": No such file or directory This board was an import and clearly not an original Arduino/Genuino. When you restart the arduino IDE, you should see a more comprehensive list of ports besides just the bluetooth port. Task c will be the same EXCEPT you'll type this instead: csrutil enable Restore the apple csrutil by following steps a and b above. Remove the FTDI drivers by opening the terminal program again and entering the following command: sudo rm -R /System/Library/Extensions/AppleUSBFTDI.kext #INAPPROPRIATE LOCTL FOR DEVICE UNRARX HOW TO#Here's how to do that: a.) power off the mac then hold 'command'+R during the restart until the image of the apple appears.ī.) when the screen refreshes, click on 'Utilities' menu then 'Terminal.Į.) Restart This required a restart in recovery mode. Then you'll need to re-enable it when you are done. You'll have to disable this process to remove the FTDI driver. The process that enforces this rule is called csrutil. Apple recently installed a new utility that prevents removal of what it considers to be critical components. #INAPPROPRIATE LOCTL FOR DEVICE UNRARX DRIVER#
