I am trying to get the Device ID of a Photon through the SWD interface (I couldn’t get JTAG to work). I am in J-Link Commander and trying to read the memory location 0x800473C for 6 bytes as follows:
J-Link>mem 0x800473C, 6 0800473C = FF FF FF FF FF FF
As you can see, I am only retrieving all ones. Can anybody tell me what is wrong? Am I reading the wrong memory register?
Thanks in advance!
