Using Debug brick


Recommended Posts

Hello list,


I try to use the jtag interface of the debug brick with a Olimex ARM-USB-OCD-H interface and openocd, but the dc brick is not recognized.

Openocd gives:


Error: JTAG scan chain interrogation failed: all ones

Error: Check JTAG interface, timings, target power, etc.

Error: Trying to use configured scan chain anyway...

Error: sam3.cpu: IR capture error; saw 0x0f not 0x01



Is there anything wrong? Has anyone used the jtag interface?
