I’m trying to get set up and running with the particle programming shield (on Mac OSX Yosemite), but I’m running into some bugs. I’ve been following these guides:
I’ve gotten through compiling OpenOCD and flashing the firmware. I am now trying to run OpenOCD with the following command:
openocd -f interface/ftdi/particle-ftdi.cfg -f target/stm32f2x.cfg -c "gdb_port 3333" -c "\$_TARGETNAME configure -rtos FreeRTOS"
I am getting the following error:
Error: libusb_claim_interface() failed with LIBUSB_ERROR_ACCESS Error: unable to open ftdi device with vid 0403, pid 6010, description '*' and serial '*'
In the second guide (README), it mentions that on Yosemite, I might need to unload/load kext:
Note: On OS X Yosemite, you will have to unload and load the kext for the serial1 to showup after every restart of the computer.
sudo kextunload -bundle com.apple.driver.AppleUSBFTDI
sudo kextload -bundle com.apple.driver.AppleUSBFTDI
I thought this might be the issue, but when I try to run either of the commands, I get the following error:
(kernel) Kext com.apple.driver.AppleUSBFTDI not found for unload request. Failed to unload com.apple.driver.AppleUSBFTDI - (libkern/kext) not found.
I’m not sure what the problem could be, and I’m stuck. Any help/advice appreciated!
