Hello,
This is my first time in JTAG on a custom board! so what are the main points to keep in mind while debugging through JTAG, and how can i do it on LPC1517 custom board via LPCXpresso IDE?
Is it like normal debugging?
I checked the 'RUN CONFIGURATION' to change SWD to JTAG, but there was no JTAG option in drop down menu! How can I make the Debugging via JTAG?
Thanks in advance
LPC15xx does not have JTAG (for debugging) - it has SWD instead, which is superior to JTAG (faster, more features etc). Yes it is like 'normal debugging'.
Suggest you read the User Manual section on debugging in the MCUXpresso documentation, where this describes how to use the debugger.
p.s. suggest you use MCUXpresso, which replaced LPCXpresso a couple of years ago.
