Rockchip PX6 with MCU STM32

[berrie60]

I dont have the above problem.
All can be saved.

Only now is whenever I start the car, the EQ will be back to default.
I need to press the EQ button/app and then i custom EQ will be back.

I think likely is some setting i miss.??

I have the same problem. Did youfind a solution?

Hello guys, can anyone with a working back camera post the exported config file so i can patch mine ? Everything works except reverse camera since i've done a factory reset/flashed another software. I have no options for back camera except "camera: normal/mirrored" in factory settings. I've opened my own config file and i think this is the option i have to modify, but i don't know what to modify here.
Thanks

Hi.look this. Maybe reinstall Factory apk ?

 

[r473r]

Hello! I've just got this unit from Eunavi for my BMW E39. My data is following:

Android Version: 10
Hardware Information: RK3399 - ROM 64GB - LPDDR4 4GB - 1024X600
CPU: 8 Core (Quad Cortex - [email protected] Quad Cortex - [email protected])
Kernel Version: Linux 4.4.167+ - Thu Aug 6 16:04:11 CST 2020
OS Version: KC1E0130-P01-11.1.4.8.1 - BLINK161 - 20200806 - N3
MCU: STM32 - 20200721 - 11 - KC6 - 40

The device works pretty good, except the following issues... There is almost no bass on whichever type of music it plays. Bluetooth, radio, youtube... Everything is flat at sounds terrible. DSP settings (EQ) helps a bit, but still very poor flat sound, much worse then my old android non-dsp unit... Then I discovered the settings screen for DELAY and I tried setting rear speaker values to more then 200 and BAM... Great and very clear bass is there... But whenever device resets, it loses the settings Actually it visually shows as its still set to previously selected value, but the effect of the value is not applies, up until I try to re-set the value again (playing around with the value restores the bass immediately)... Any ideas on how could I solve this, to avoid having to play around with the settings each time I start the car ?????????

Do I have to root my device before I can see Android_config.xml?
I cant find it.

Someone have connection and access to Android Auto ?

 

[MrSchlumpf]

My phone is always searching for it. But it doesn't work over WLAN or Bluetooth. But that's ok, because android auto can only use your phones GPS and that sucks in my case. I use Google maps on the headunit with a WiFi connection to the phone. Navigation works like a charm. What I miss is the hands free speech assistant.
You can use Android auto with the built in app "easy connect " or maybe it works by usb?

 

[berrie60]

Thanx. I have to look at easy connect.
I dont know how to connect my phone wifi ti the head unit.
I google for it.

You have to make a hotspot on your phone and log the headunit in. To automate it use an app like "carspot ready" for it.

Anyone has a solution for a whitelist app or mod? I'm in stock with root and need YouTube to resume playing after sleep. That option was available on my old mtcd with hal9k mod. This unit kills all proceses, even waze/maps... That is a real bugger.

 

[tvladan]

Have you ever found the code for this?

Hello
for this car radio has the MJZ setting line you need a code and does anyone know it??
what does mjz mean..thank youView attachment 5547663View attachment 5547665

So... This thread seems kinda dead... Probably because this stm32 units are kinda crap. Still... Does anyone have a .img rom file with the latest updates? Preferably starting with os_update_KC1E0129-P01-1.1.4.9.1_20210812 or later?
I messed with mine and lost sound (again) and none of the img's I could find online solve my sound problem...
Maybe someone can make a rkdump file form an existing running board with dsp. I would really appreciate it.
Thanks.

Thanks for the answer. In tried both 9 and 10 in that drive link a couple of days ago. No luck. Both boot up just fine but with no sound. I have an unbranded with DSP china 9 inch device. It came with fake 10 from the seller. (can't get a reply from the seller... So that's a dead end)

I backed up my partitions (via adb pull) but i missed the bhd one.

Flashing either img from that folder results in working system with no sound, than if i flash my backed up partitions one by one(rkdevtool via maskrom) the situation either remains the same or i get stuck at android logo.

Also those images seem to be from a boison device. I had the stock launcher with big tiles and a slightly newer model. (2021 build).

hello this is my headunit I put the picture with the info in the attachment. Is there any firmware avialable to flash on this one? Since I had some really big trouble with the wifi and my mobile hotspot, I would like to know if there is any upgrade or better firmware. Also the radio is really slow as it open google maps it takes forever to load. Does anyone have a step by step guide to do flash upgraded firmware?
