Other Parts Discussed in Thread: CC2530
Hi.
I am trying to connect USB ZigBee CC2530 dongle (from CC2530 Mini ZNP kit) to AM335x starter kit board running EZLinux.
I rebuilt the kernel with the CONFIG_USB_ACM & CONFIG_USB_SERIAL_TI (ti_usb_3410_5052) options enabled.
When I attach the ZigBee to USB the new device /dev/ttyACM0 comes up, but opening the port fails.
Has anybody any idea on what to do?
This is what happens when USB is attached and minicom tries to open the port:
