Differences Between Warm Reset and Software Reset of C674x

Hi,
Let me do some sanity check with code and get back to you on this.
Thanks for your patience.

Hello Tsutomu,

I will try to find the difference and significance of SWRESET in SoC specification document and update you.

Thanks for your patience.

Hi Tsutomu,

Like the warm reset, the software reset preserves data in the internal RAM and initializes the all internal logic to the default states?

I've tested sw that has reset code (RSCTL) and able to retain the "Shared RAM" content after I did sw reset.
Yes, it would preserves the internal RAM content when we do sw reset.

Titus,

Thank you for the test. It will be of much help for me. But do you have a specification on the software reset?

What do you mean by specification of sw reset ?
If you expecting timing related, then, Senthil would assist you on this.

Titus,

Thank you very much for your reply.

Since my customer is designing a C674x board now, he is very interested in the device pin states at the software reset. The data sheet says "All device pins go to a high-impedance state" at the warm reset. Does it also happen at the software reset? Thanks.
