DDPAI Mini One - is it a new version ?

The official way to get a firmware update path is to send the POST request to http://apphw.ddpai.com/d/api/v1/version/check with the JSON encoded model name.
It was necessary to get the Mini 5's 4G bracket working.
I think it is about "to enable the data upload into chinese cloud".
However, I've been able to download China-based firmware in the past by going to the Chinese language section of the website. Seems like now that is no longer possible.
Yeah, the firmware download was available after clicking on the CN button, but not anymore.
I have ordered the second miniONE to dismantle it and search for the console UART0 pins.
 
miniONE has disappeared from the DDPAI website, is it officially discontinued now ?
 
I have managed to connect to the UART0 RX/TX pads on miniONE after disconnecting the IMX307 sensor, and to record the full u-boot+LiteOS bootlog. There are not that many surprises
(HI3516EV100 CPU, 64MB RAM, FORESEE 32GB eMMC, RTL8189fs WIFI, SC7A20 accelerometer. ChipON 8bit microcontroller KF8V11 https://www.chipon-ic.com/en ), the firmware has buggy USB storage mode.
Looks like a cheap mini3 brother (like mola N3 is for mini5).
It is possible to flash the Linux image from M6+, but there is one problem: missing ready to use Linux driver for the IMX307 sensor. I have found some source code on github,
but it is only for LiteOS and needs to be adapted. Playing with mini5 is more fun.

Hi @helg

Can you tell me what firmware you have on your camera?
I think I have the Chinese version of MiniONE with 4.5.2.10 firmware.
The DDPAI support sent me the v4.5.0.34_180914 firmware (downgrade ?!) but they don't know if it will work either. There is a possibility to turn it into a brick.

Thank you.

I need to solder a very fine pitch UART RX cable to dump my firmware from eMMC (after breaking the boot sequence in u-boot). This data is from the UART TX output:

I am not aware of any publicly available miniONE_nightvision firmware, can you upload this one for a closer inspection ?

Sure, here.

Do you have 4.5.2.29 firmware or newer available to download ?

P.S. Also, an interesting topic related to miniONE can be found here, but it's harder with creating an account ....

No, it was factory installed.

Your v4.5.0.34_180914 firmware version is for the IMX323 sensor, it may be a very bad idea flashing it for the IMX307 sensor.

The DDpai support team sent me the firmware but I never installed it ...

DDPai Mini One low light parking recording sample.


Comparing it to DDPai Mola N3.



DDPai Mini One low light driving sample.


Comparing it to DDPai Mola N3. You can see the Mola N3 booted up faster and started recording first before the Mini One. Both devices are powered by their respective hardwire power kits tapping at interior fusebox.


This concludes my findings on Mini One. Overall it is limited by low bit rate recording due to limited internal storage, and also by SOC limited to 3.75 MB/sec bitrate output. There is not very much else to report because at the ~US$50 price range within the DDPai family, the Mola N3 has a stronger feature set, better heat sink design, and better sensor and SoC combination.
He Richard,
Cross-link: observation on power consumption between Mini One and Mola N3.

Hey,

I've set up a DDPAI Mola N3 GPS dash cam & connected it to a micro UPS with 10000mah. Have set the parking mode to 6hrs.

But after 4hrs, the battery goes dry and my dash cam gets switched off.

Can anyone guide me,
1. what's the power consumption of my dash cam in parking mode.
2. What else dash cam settings can I change to ensure more back up.

Kindly help..
