Exploring the problem of popping sounds

longone

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 OK

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?

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?

Slavus После обновления MCU 2025.07.15 физические кнопки перестают работать, который подключены к проводу key1. Программирование ничего не дало, они не программируются.
Работают только кнопки , которые по кан шине.

dudu-lai After the update of the MCU 2025.07.15, the physical buttons stop working, which are connected to the key1 wire. Programming has done nothing, they are not programmable.
Only the buttons that are connected by can bus.
