DUDU7 LATEST MCU FIRMWARE.

DUDU-Meng Спасибо. Пока попробовал установить снова прошивку MCU, И установка прошивки со сбросом данных (Factory Reset) не помогла.

Will you still have this issue when using other versions of MCU firmware?

makc-ko

DUDU-Meng Нет, это только на этой версии. На других версиях MCU хлопки во внешнем усилителе при выключении магнитолы или перезагрузке.

Can you measure whether the amplifier control cable still powers on after you have a silent ignition issue?

makc-ko

Пропадает управляющее напряжение на rem.

Could you help me check the REM voltage when there is sound and when there is no sound? It's best to take a video or photo, thank you

DUDU-Meng

One more question: Do you have the ACC power-off delay enabled? If so, how much time was set? You can turn it off and try again to see if this feature is causing it.

DUDU-Meng Пробовал отключать задержку это не помогло. Ставил 1, 3, 5, 6 секунд это тоже не помогло.

Что в ней исправлено?

One of my 9.5 inch DUDU7-9.5-8-128 unit started behaving weirdly, it often turn off completely even after 2-3 hours of ignition off, sometimes on starting the car, after booting completely, bottom bar icons disappear.

MCU version is from 2024, and firmware version is 3.7. Factory Reset won't solve this problem.

Can this MCU work on my unit?

DUDU-Meng Try this version

A huge thank you! With this version (s3-dudu7-mcu-260529), I got the hands-free opening and closing back on my trunk (2021 Peugeot 3008 PHEV). You're doing fantastic work!

DUDU-Meng

makc-ko May I ask if upgrading this 260529 version MCU still doesn't solve the problem?

DUDU-Meng

Modified some logic of REM after ACC was powered on.

makc-ko

DUDU-Meng Частично, но иногда слышны хлопки когда завожу машину. Было бы идеально если бы можно было регулировать не только задержку выключения устройства, но и задержку выключения REM внешнего усилителя. И задержку выключения звука.Всё это можно менять в MCU, я так полагаю.

DUDU-Meng

makc-ko
I'm sorry I didn't understand what you meant. Do I need to manually turn off and then turn on the REM switch after ACC is powered on in the MCU version 260529 to make any sound?
I saw that when you start this version, you will hear a beep, right?

makc-ko

DUDU-Meng Версии 260529 всё работает. После включения и выключения ACC сам обратно включается REM. Руками переключать не надо.

From the perspective of MCU design rules, this issue is multifaceted. You can upgrade the MCU and upgrade the system to check the battery voltage. Only then can the main root cause of the problem be found

DUDU-Meng

makc-ko
260529 version of the MCU has already solved the problem, right?

makc-ko

DUDU-Meng Да. Но остались иногда хлопки в усилителе при выключении.

DUDU-Meng This doesn't happen on another unit a 10-inch DUDU7 installed in that vehicle using 9 to 10-inch frame and it was working fine, didn't go shutdown in less than 72 hours. Purchased the 9 inches to be used and it is giving this problem, sometimes, it turns off even after 10 minutes of ignition off, and when put the switch on ACC, it starts from booting which means it turned itself off. Battery voltage 12.46 when I saw this condition yesterday.

There are many causes of sleep failure. In the 260430 system, we fixed the RDS hibernation failure issue, meaning that if you were listening to the radio before shutting down, the next startup would most likely restart.
There are many other causes of this phenomenon: after sleep it still runs a high-frequency app, and the total current exceeds 1.16V (the voltage conversion current at pin 13 of the MCU can be measured).
Apps running in the background that have actions that prevent hibernation or crashes can also cause this issue.
Shutdown after sleep exceeding 70 hours (MCU firmware default)
After a certain number of successful sleep cycles, it will be forcibly restarted once (system count).
There are many policy discussions about dormancy
I have an MCU version here, please try it. If it solves the sleep issue, this version removes current detection during sleep (MCU pin 13 voltage).
