Title: Error conncting ARM-USB-OCD-H to openocd
Post by: kkry on November 07, 2021, 11:48:34 am
I launched openocd with the command:
openocd -f openocd-zcu102-olimex-arm-usb-ocd-h.cfgThe output:

Hmm, is it FTDI or libusb driver in the OpenOCD version that you use? Might want to edit that in the cfg. Also why only one interface is visible... It should list both the RS232 port at the back and the USB-serial converter. There is something fishy here. Maybe the interface is black listed?
