Hi Giovanni

for jtag connection one can look at EVK schematic on

thank you !! I would like to ask you another question how is the processor (a53 or m7) decided on which is debugged? I am looking at the demoapps for IAR
(I am interested in loading my FSM on the processor) I would like to debug on port jtag. How can I be sure the finite_state _machine with debugging is loaded on
the m7 core? thank you very much

each debugger script is named *a53 or *m7. Please look at documentation included in SDK.
