I tried connecting JLink debugger to OMAPL138 eval board. But the tool (used to connect debugger to board) is displaying a message as "J-Link found 0 JTAG device, Total IRLen = 0 JTAG ID: 0x00000000 (ARM9) ". Would you please let me know why this is happening?
You are in the wrong forum. This forum is for the Stellaris family of processors.
You would probably be better served in a J-Link forum or a forum for the OMAP processors.
