66AK2G12: GPMC and EMU pin conflict

Srikanth Kacchu1

Part Number: 66AK2G12

I planned to implement 20 pin header mating for XDS200 emulator in my board. This emulator pinout has EMU02, EMU03 and EMU04 signals which are pin multiplexed with GPMC address which is already used in my design for NOR Flash interface.

Can anyone say how to implement both emulator and GPMC?

Hi,

If the pins can be muxed as EMU & GPMC, then you cannot use them both at the same time.

Best Regards,

Hi Yordan

I guess most of the designs implement the GPMC interface. If it so, can't we implement the JTAG configuration with additional emulator pins? Only minimal JTAG configuration to be implemented?
