Exploring the problem of popping sounds

Janebo

dudu-lai hi, I tried to make a video, it's little bit problem to hear the sound in the recording, even it's very loud, My phone mic is not great catching sounds from the subwoofer, but the sound is there when you see the screen go black on shutdown

Upgrade the new MCU firmware to test whether the problem is solved
If the issue is still not resolved, please provide the upgraded MCU version information and a video showing the issue reoccurring.

dudu-lai that's ok, I will update it, should the Isec6318update be included to the usb stick?

dudu-lai

Janebo yes

dudu-lai hi, pop sound was still there, this time I can hear the amplifier is delayed shutdown, it should be the other way around, first shutdown amplifier then shutdown DSP/preamplifier, I forget to take pictures of the system because I was getting problem with the MCU hardware keys, so I flashed the last MCU again,

Janebo If the issue is still not resolved, please provide the upgraded MCU version information and a video showing the issue reoccurring.

Janebo

dudu-lai hi, I am online, I didn't Flash The head unit again since there is a heat wave here now, it's too hot outside, I can try later today today when it's cooler outside, I'm experiencing everytime when I flashing new firmware then I have to adjust my settings and relearn the MCU key also,

Janebo OK

Hello @dudu-lai ! I'm experiencing a loud thump/popping sound on startup with my Dudu7. Everything on SWC with Canbus is working - would you be able to suggest any options for me -

My car is a Fiat 500e 2016, from what I understand it does have a factory amp, I have not been able to make any changes on the Vehicle settings for the amplifier setting through canbus settings.

Here are the details I can provide attached. And link to video hopefully you can see.

longone Hi, I have submitted a request to view the Google Drive you shared, please approve it.
If the AMP settings or volume in the vehicle information cannot be adjusted (non-CANBUS activated AMP), it is usually activated by the control line. Can you confirm this?

Janebo

dudu-lai hi, I flashed MCU 20250715
I'm not able to use this version because it make my MCU key not working properly, not able to reconfigure the key with MCU key app either

dudu-lai Review request approved! Yes - correct, using amp-c line is connected and is how the dudu7 is activated. But I still cannot make any changes to the actual settings through the vehicle information screen.

Should I be using a different canbus vehicle setting?

dudu-lai

longone No, you just need to update the MCU firmware.
Please make sure to connect the car AMP control line using the AMPcont cable on the A connector of the DUDU.

dudu-lai Updated with the latest MCU from original post - and that appears to have taken care of the worst of it! Thank you!

Janebo MCU version 20250715 has been released. Currently, no other users have reported abnormal MCU button operation. What kind of button are you using?

Janebo Could you please print the ylog of the MCU button that cannot be learned using the MCU250715 version?
