DUDU7 LATEST MCU FIRMWARE.

Like I mentioned in my post "I first updated my normal firmware to 250820 (other users: this is beta, not generally available)."
The current stable version (official as DuDu calls it) is the 20250729.
Normally I would not mention the beta version but after the several issues and fails with the OTA updater, I wanted to be as complete as possible.

You can become a beta tester: This FAQ, bullet #1. https://forum.dudu-auto.com/d/110-faqcasto-zadavaemye-voprosy
I do not know if this is still open. Use the translate functionality.

surfer63 ok, i understand now. I have exactly the same problem with OTA updater when i try to update BT via OTA. After couple of times it updates, but the updater is buggy indeed

It is now also addressed in the Telegram group. Hopefully DuDu will pick up soon.

Hello, Do you have the older 2024 stm32ud.bin MCU file?

I installed the new stm32ud.bin 20250715 MCU version from the 2024 version I previously had on my DUDU7 and it disabled my chassis's hardware buttons. Once I reselected the Raise CANBUS, 2 of the 6 buttons became functional and hard coded to "Back" and "Radio" functions with the others becoming inoperatable and no longer able to remap per the "MCU Panel Mapping" App. It sounds like the new MCU only reads the buttons as preconfigured options per the CANBUS now instead reprogrammable keys.

Btc3111 Hi, I experiencing the same problems as you with the hardware button as you, didn't work and could not configure the button with the MCU key app, I solved it by flash the previous MCU firmware, lucky that I saved my MCU files for the other MCU,

Does anyone have a file with the 2024.01.24 MCU version? Or another one from 2024?

also after the MCU update on the version of 2025.07.15 lost control of physical buttons. Maybe who's throwing MCU 2024.01.24

Can I update the mcu but remain on OS 3.5? I do not want to lose CarPlay in PIP so I want to stay on 3.5. I do have some cellular connection issues and hopefully a mcu update may help.

DUDU-Meng hi, i do experience the after reset explosion sound on my unit (DUDU6). Is the fix by updating the MCU? I have canbus but theres another thread saying the box sending incorrect speed (and veri high 500kmh). Is this related to MCU? Also, i have limited data provided by canbus. Only door status, swc, incorrect speed. Other than that no like steering angle reverse projection, headlight trigger, reverse trigger, reverse sensor also suddently not detect (rear right, already try replace but still got issue). BTW im using Raise Geely Persona 2015

hafiz_tahir This is caused by the DSP suddenly losing power and then being powered back on. Using conventional restart methods will not produce this sound.

DUDU-Meng i see, noted on that

I find latest MCU firmware "7870-dudu7-mcu-250830" because mine with my new dudu7 is 2024.01.24.

But what is latest bluetooth firmware ? mine is 2025.03.27

=> DUDUOS is V250905

Is this the official BT firmware version or a test version which you received on this forum?

Mikescotland

Benlatak but why? Have you got specific faults that are known mcu update will fix? Because you may kill the unit doing so and there isn't any recovery in FYT from this incident.

surfer63

We mix 2 things here: latest BT-firmware and latest MCU-firmware.
Like @Mikescotland mentions: Be very careful with upgrading the MCU-firmware.

Slavus

surfer63 received from OTA

Benlatak

Slavus because you are beta-tester or something else ? No OTA received for me except OS update V250905.
