DuduOS help on Teyes CC3

Saburo

DUDU-Meng On my side, the SWC will work as expected. I only have the black border issue.

HAccord8

DUDU-Meng yes unfortunately they still break (same like version 2.25.1020.0906)after device goes into sleep mode and wake up. The only way to fix them is to kill the app and reopen or restart the unit.

The version 2.25.0926.1708 didn't have this issue at all but like you said FYT developer changed some logic

HAccord8

@DUDU-Meng I am sure any DuduOS update will have CarLink version after 1708 and it will break my SWC. I am not if that can be fixed since the app comes from FYT. Can you give feedback to DuduOS developer to make CarLink app a User app and not System app so i am able to downgrade to CarLink version 1708 in case i decide to install final version of DuduOS 3.7

The user app can be downgraded but system app cannot

DUDU-Meng

HAccord8
This cannot be converted into a user application; it requires system privileges to function properly.

DUDU-Meng when the new DuduOS arrives the final version of 3.7 and i update from my beta the CarPlay will be upgraded and my steering wheel controls break? What i will do then?

DUDU-Meng

HAccord8
We've been unable to reproduce the issue where the steering wheel controls don't work with CarPlay, and other users are experiencing normal functionality. Therefore, I'm unsure where the problem lies on your end. Have you tried updating the MCU?

HAccord8

DUDU-Meng that is my MCU version and sorry i am not sure where to find the latest.
Also, as we are CarLink newer version is breaking the SWC why do you think MCU has to something with it?

Also, you mentioned you tested on Cc3 and it was fine? What was the Firmware version, MCU version on that Cc3? And how did you connect up the SWC on that CC3? Through canbus or direct to headunit? And did you map the keys from DuduOS settings app?

My CC3 has already flashed the MCU's TZY into the NOR base version using the device.
Since TZY's MCU requires MS to perform certain checks, it disrupts the 360 layout. That's why I switched it to NOR several years ago—testing confirms normal control.
Looking at the image, your MCU is from 2022. Check if there's a newer version available and try upgrading. The resistive SWC handles the MCU's operation.

DUDU-Meng Which Firmware do i need to install for this? Ive found 2
Global_DUDU7862_2511041806_2510200925.7z
and Global_DUDU7862_2503070219_2502111106.7z

Awaiting Beta test approval but have got some responses on telegram yaoxilong. Anxious to install on my 10.1 Joying Radio that is 1280x800

JRANGER615, it would be better if you showed some manners and started a new thread instead of hijacking a thread about a different topic.

JRANGER615

HAccord8 my bad, i thought this was about the latest 7862 help thread didnt realize it was only specifics to the apl

DUDU-Meng thanks.

Can i switch to NOR?

Also that is the last MCU i found from 4pda? Any suggestion where i can find? Teyes would not help with anything

DUDU-Meng

HAccord8
NOR can be upgraded with any custom MCU firmware, but it cannot be restored.
TZY cannot directly upgrade NOR; it requires programming devices like JLink or GDlink.

HAccord8

DUDU-Meng if you could pass me on some instructions on how to achieve it. I can give it a try

and also suggestion where to find the latest MCU

DUDU-Meng

HAccord8
If you want to flash it as NOR, you'll need a programmer, which can be a bit of a hassle.
You could try looking for other versions of the TZY firmware to upgrade with.
There are many CC3 users in the Telegram group, but none of them have raised this issue.

HAccord8

DUDU-Meng yes my friend i strongly believe none of them has updated to any version after DuduOS v251104 that contains the CarLink version 2.25.0926.1708, which is the version without any issue.

I'm sure when new DuduOS beta version is released with any CarLink version after 2.25.0926.1708 and anyone running TeyesCC3 with resistive SWC will face this issue.

I will look for newer MCU version and see if it helps.

Could you do me a favour please? Can you pass this feedback to FYT who develops CarLink, they might have a solution
