ADAV400 register dump using Sigmastudio


I am working on a troublesome legacy design using ADAV400 audio DSP.

Can I get a register dump from the DSP without creating a project in Sigmastudio?

I hope to be able to boot from the existing host, then to switch I2C lines to USBi and try to read the registers of the DSP.

Does this idea make any sense?

Are there other ways to implement register dump without intervention from the existing host?

Thank you for your help!
