    Yamaha RX-V581 DSP dump files

    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.

              Request: SPI Flash BIOS Dump (Winbond 25Q128) for Dahua NVR4216-4KS2
              by spmetroil
              Hello,

              I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
              The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).

              I have a CH341A programmer and I already attempted the following steps:
              1. Identified the correct chip (W25Q128, 3.3V SPI flash).
              2. Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
              3. Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI
              ...

              Canon DR-1210C flash dump request
              by bamdad61
              Dear folks, recently got a canon dr-1210c and it worked perfectly just for one day. Right now it shows all possible errors on the screen and do nothing. I tear down the device and found a 32 pin plcc flash chip. I thought reprogramming firmware might be helpful. The firmware update file from canon support include a dll file which doesn't help. So if anyone has the dump it would such a great favor to share.

              Nikon D800 camera - flash don’t work and capacitor don’t charge
              by corrize
              Hello, I'm stuck in troubleshooting…
              The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

              In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
              When I press the flash button, it's detected by the system, flash icon appear on LDC display....

              lenovo P720 SIO flash dump
              by numerlor
              Hi, the SIO firmware flash in my lenovo P720 seems to be corrupted, after a reboot POST fails with CPU1 fan failure and all fans set to max, proceeding with booting shows SIO FW no response.

              I've tried using the lenovo sio update utility but that fails with "EC Autho Value not Match" when the system reboots for the update. The efi update tools has a S04FW.cap file but it's 256kb which seems too small?
