Yamaha RX-V581 DSP dump files

[nams2590]

Hello everyone,

I'm currently trying to troubleshoot a Yamaha RX-V581 amplifier.
The whole HW looks fine to me but I notice the DSP flash memories are empty.
As a result their is no sound on HPs and speaker menu is not available.
Does anyone has these DSP flash memory content?

The related 2 memories are Winbond W25Q32.

That would help a lot.
Thanks in advance

Best Regards

Hello,

FYI, I'm trying to get in touch with Yamaha audio support service.
Hopefully, I'll get the DSP flash memory contents.
If yes, I'll post these on the forum.
Finger crossed

IC44 and IC48 from RX-V583. Both SPI chips 25Q32FVSIG. DSP circuit does look very similar, so give these a try.
