Is there a way to determine whether the code’s running on a JTAG-enabled or a ‘regular’ ME/ME9210? (I’m talking about when running the code from flash in a standalone situation, not during debugging) ---

The following API call may help you out. The function, “are\_we\_in\_debugger”, located in netos7X/src/bsp/init/armX/NCC\_INIT.c returns a Boolean indicating if a debugger is present or not. More information on this function can be found in the API reference guide under the “Miscellaneous” category. Declaration BOOLEAN are\_we\_in\_debugger (void); Return values Value Description 0 No debugger detected 1 Debugger detected ---

Thanks for that, but not quite what I’m looking for. I want to tell whether or not I’m running on the JTAG hardware platform, even with the JTAG emulator not connected (so that I can enable/disable use of the second serial port)
