Hello,
I have been studying the F280049M controlCARD design. It looks like the one has to set the card to debug differently than for flash programming. If I read the schematic correctly, the JTAG signals are active when one wishes to program the flash, but the SCI pins must be active to debug. In a standalone design we will most likely be using an XDS200 programmer/emulator, but I need to know how to wire the CTI20 or TI14 connector to the target DSP, which will be an F280049PZ 100-pin device. Do I wire in the EMU0 and EMU1 to an SCI pin pair (TI14 connector) or EMU0 – EMU4 (CTI20 connector)?
Thank you,
Errol
Errol,
Do you plan to debug and program the flash with the XDS200? If so, you would just connect the JTAG or cJTAG signals normally.
There is a snippet in the datasheet with respect to no EMU support so you won't have to worry about those signals:
I think there is some misunderstanding in the role of SCI pins. Can you help me understand how they fit into the picture?
