fail to boot up again for c6748 after pulling the "reset" pin low

hong wang

Hi,all

When power is on,the c6748 working well on my board.

There is a button between the "GND" and the "RESET" pin of c6748.

now I want to reset the dsp,so I push the button down ,but c6748 doesn't work, I connect my emulator(XDS560) to dsp successfully,so I think it is boot faliure reason.

What is the reason for this?

best regards

Hong Wang,

What is the C6748 doing after the RESET button is released? I am asking what you observe in CCS through the XDS560 emulator.

Does the RESETOUTz pin go low when the RESET button is pressed?

Section 5.4 "Reset" of the datasheet explains the various types of resets and how the pins are used to assert each.

What boot mode do you use?

What have you learned since posting your question?

Regards,
RandyP
