I am attempting to integrate JTAG Boundary Scan onto an existing ARM9 board using SAM-ICE as the JTAG Emulator.
One unfortunate oversight is that CPU/System Reset (
nRST or aka
nSRST ) was not brought out onto the header on this board. However, JTAG
nTRST is exposed.
Would I still be able to execute JTAG Boundary Scan without access to system reset pin? The documentation on this is not clear, as both reset pins are technically "optional".
