OMAPL137-HT: Emu pins

Part Number: OMAPL137-HT

Hi team,

I got a question from customer.

"I am designing a board using OMAPL137BPTPH (the high temp component, 176-pin package) and I cannot find the EMU pins for the JTAG emulators. How do I perform JTAG emulation, debugging with this component? "

Thank you very much for your help.

Best regards,

    The JTAG signals are used as the primary interface for debugger functions.  What debug functions are you trying to use that require the EMU signals?

    Regards,

    Hi peaves,

    Thank you for your help.I got feedback from customer.

    "I don't know. I see some OMAP devices have EMU0 and EMU1, but not the one I am using. I was hoping you could clarify what those pins are for."

    Thanks a again.

    Best regards,

    The OMAPL137 design has EMU[1:0] pad, but it does not appear they are connected to pins in the OMAPL137-HT device. These signal functions support board-level cross-triggering and HSRTDX. However, HSRTDX is a feature that is no longer supported in CCS.
