General New Joying Android 10 UIS7862 Octacore 1.8GHz (4GB RAM, 64GB flash)

The atoto one will most likely work with atoto units only. All other DVR cams are most likely the same thing just with a different brand sticker slapped on it. I personally wouldn't use those DVR cams since they're limited to 720p resolution at a measley 30fps. They also feature ADAS but most people end up turning it off since alerts are annoying and delayed and end up being dangerous if you actually rely on it, so it's a toy at best.

The atoto cam is actually an Anytek x28 cam, and it works with other "none atoto" HUs...
I don't care much if it is full hd or only 720p -720p should match our screen resolution anyway. So I think pic quality at night and app quality matters more.
And yes I do know it's a toy gimmick -But my car is all about toy gimmicks
I also realize that none of the hu resellers produce their cams, so identical are available from other cheaper sources. But I have read that some cams looking identical have different hardware inside, so I'm a little worried that cheaper version might be inferior.

Anyone have any experience with these dvr cams?

Hi Guys,

I'm trying to source a third party display to fit in a custom dash kit for my vehicle. I'm not too familiar with firmware and drivers but I write Javascript evey day, can solder, and fabricate reasonably well.

Does anyone know where to start?

• It sounds like the unit has to be using LVDS or MIPI to talk to the mainboard (because that's what the CPU supports), but beyond that I have no idea what to look for in a display controller.
• If moving to a different resolution screen, are there config files that need to be updated in the firmware? Is this just like updating a JSON config?
• Has anyone tried swapping two different Joying screens on the same head unit?

If it can help you I found that file online. It's a collection of configs for different display. I used one of the file to make a 1024x600 display work on a Joying head unit that came originally with a 1280x720 display.
If you find a display that match one of these config files you can flash it by copying it on a USB key along with the 'lsec6521update' binary like any update or firmware.

EDIT: XDA didn't like me attaching the photos, just got broken links so I'm sorry that they're embedded like this.

Joying just sent me a review unit of their new 10.1" Android 10 head unit so I figured it should have its own thread. It looks like they're pumping out updated versions of all their previous devices by the day so I imagine they'll have versions of this in all the different screen sizes soon. First impression is good. The interface is appreciably more responsive than the Intel unit I currently have in the car. I'm working on some videos but figured I'd throw some pictures in here. Here is an unboxing and interface tour video:

The PCB looks is clearly iterative but looks to have some significant redesigns, especially with the power supply which is much larger than on the previous Intel design, through that might be required for extra derived voltages for the new UIS7862 SoC.

The previous Intel PCB used an STM32 MCU in between the main SoC and the bluetooth module which probably contributed to the difficulty interfacing Bluetooth devices that weren't specifically allowed by Joying. The area where this chip was now looks to be filled with power components though the same Bluetooth module is still used. I'm hopeful that this means there's direct communication from the SoC to the BT module, but that'll take more digging to determine. There is also a new general purpose ARM Cortex-M4 MCU added between the SoC carrier board and the DSP chip (GigaDevice GD32F330R8T6). I'm curious if that's taken the place of the old STM32 chip or if it's used for something else. Hopefully I'll be able to determine what it's used for, but I'm not touching anything until I get it installed and reviewed.

The green PCB is the Intel board and the yellowish one is the new Android 10 board. Of note is the fact that the new PCB has Joying's name silk screened onto it where the old Intel one didn't. So, at bare minimum, this board is spun just for Joying, even if the only differences are the silk screen layers.

Any requests for specific details?

how is the heat sink attached to to cpu? and what are the dimensions of heat sink
thinking about adding fan when mine arrives. My px units ran hot
thanks

Sure if you are going to encode for hours, a fan might become handy...

My unit runs at 60 at ambient (23°C). Worthwhile question...

WATERCOOL IT!
No honestly I hate fans so if I don't feel it slows down due to thermal throttling I will just let it swet.
60°C at idle? Seems a bit high if so. But without knowing where the sensor is placed, this reading isn't very useful.
Anyone knows what temperature the unit starts throtteling? That could give an idea about what temperature the manufactor believe is safe.
Do we know what process the soc is build on?

 

[TacticalSmoores]

I see 40°C+ ambient temps in the summers. There's no airflow behind my headunit. I think I will need to invest in a fan and heatsinks.

I'm thinking Noctua's NF-A9 FLX (92mm) would work pretty well in a car. It comes with adaptors that should bring 15v down to 12v. And, at 17db you're not going to notice it behind the dash.

2 days ago I replaced my tomostrong 4core 16/1gb headunit with a mekede 7862 128/6gb unit. So far I have been quite happy with the new unit. But I just realized that bit perfect audio output through the spdif does not seem possible :-(
Anyone knows if the 7862 can play bit perfect audio through usb with usb audio player pro?

I am not sure that this a Joying problem but I am asking anyway.

I recently checked my Google devices page and cleaned it up by signing out of old devices which I do not own anymore. Mistakenly I also signed out of my Joying headunit remotely.

When I got in my car the next day I could not sign in to my account anymore. The Check Info window flashes and returns to the previous window. This happens with Play Store, Maps, Chrome, etc.
I did some research and though it might have something to do with the Android System Webview issues of recently. I tried every solution I could find but to no avail.

In the end I decided to do a factory reset but to my surprise, I still can't sign in to my Google account after a reset! The issue is the same, the Check Info windows flashes and disappears. So either the Joying factory reset is not a deep enough reset or something is wrong with my Google account?
I am very hesitant to sign out of my other devices to see what happens there.

I would appreciate some help.

Not sure if this will be relevant with the Joying or not, but just found the USB Mode toggle on the UIS7862 IDoing. It's the "..." menu at the root of developer setting. Two items in Chinese, top one is host mode, bottom is device mode. Got USB Debugging working fine even with usb-c cable from my laptop.

What is the password for developer settings?

on my Idoing, it's 3368

Replying my self (going mad?)
Unisoc 7862 is most probably build on TSMC 12nm. So same process as Geforce 10/16/20 series.
Would you be worried if your geforce ran at 60°C ?

 

[Allan_Hun]

on my Idoing, it's 3368

So same pass as factory settings?

yes

How can I reboot my unit without disconnecting the battery?

I can't speak for Joying, but the Idoing has a reboot option in the status bar as well as a reset paperclip hole

Thank you. Stupid me totally forgot about the reset hole...
My old ****ty 1Gb unit had reset in factory option, so only used the reset hole once trying to update the unit.

 

[xdamember2]

Do you, or anyone else, happen to know what frequencies the 7862 supports?
I need 800, 1800 and 2600mhz for 4g. It would be a deal breaker if I have to connect through my phone's hotspot...

Here's what Joying told me:

item only supports the below types:
GSM: GSM850 EGSM 900 DCS1800 PCS1900
WCDMA: BAND1 BAND2 BAND5 BAND8
TD-SCDMA: BAND34 BAND39
TDD-LTE: BAND34 BAND38 BAND39 BAND40 BAND41
FDD-LTE: BAND1 BAND2 BAND3 BAND5 BAND7 BAND8 BAND20 BAND29A

and not supported types:
AT&T: BAND12 BAND14 BAND17 BAND29 BAND30 BAND66
Verizon Wireless: BAND13 BAND66
T-Mobile: BAND12 BAND66 BAND71
Sprint: BAND25 BAND26 BAND41
