Hello,
I am new to OPENOCD. I am trying program/debug TIVA TM4C1294XL board with emBitz and OPENOCD. I am getting errors as shown below. I have also pasted output with -d3 switch at the bottom. Does anyone know how to resolve this?
After a couple of tries the processor does get programmed and halts at the RESET entry but its very unreliable.
Thanks.
