tms320c6424 warm-reset

Other Parts Discussed in Thread: TMS320C6424

Hello.

I want answer to problem in my circuit.

I am using TI's chip tms320c6424.

By the way, I have a problem that warm-reset does not operate.

It includes two of the DSP in my circuit.


test results are below.

1. When driving one DSP or two DSPs reset, RESETOUT signal has low to high transition.

2. I have changed the R447 resistor value to lesser(1.2k ohm), but the board doesn't operate.

3. When driving each DSP reset pin(with one DSP), but the board doesn't operate.

4. I think that PCB Artwork has no problem.

5. I connected the reset signal to the one DSP chip, But the reset doesn't operate.

6. It changed the 3.3V voltage to 2.8V. So the warm-reset was operating successful.
