Denago 10.1" display

[HoleIn12]

Good Evening! Anyone know how to get into the settings of the Denago 10.1" Display? Not the setting can normally see on the screen, but rather the system settings.

I have seen android based 10.1" displays (carplay etc), that can get in there and reset or change the side soft buttons, etc etc... but this does not work the same way.

Thanks

On the Kandi, also a 10" Android, if you swipe up, you can get to settings and other apps.

Ed, thanks, unfortunately that doesn’t work on these carts.

I haven't seen the display of the Denago but I'm going to guess that like many other cheap-o carts, the display is not Android but a very low end tablet with an Operating System (OS) that’s probably Melis RTOS

I have one on my desk that was having an issue. Here is a pic of the only markings on the back of it.

can you take the cover off and get a few good pictures of the board and larger ICs?

Absolutely can.

thanks for pictures. It's a little tough to read any of the labels. And the MCU label has been ground off.

It looks like the MCU is an Allwinner, maybe a F1C100s or F1C200s.

to the left of the MCU is an 8 pin chip, that's probably 64Mbit (8MB) SPI NOR flash like a Winbond 25VQ64ASIG or similar. If you dump the flash contents using an SPI reader (e.g., CH341A or Bus Pirate), you could analyze the firmware to confirm the MCU and OS

the main connector is well labeled. And I see a CANH and CANL, probably for displaying CAN messages from controller and BMS.

Impressive information! They definitely tried to remove the label, but a light and magnification helped a bunch.

nice pictures

Sunplus SPHE8368 is an ARM Cortex-A9 either running a Sunplus Proprietary RTOS or an embedded linux like Melis

Do you have or know of any update files for your display?

ESMT F50L2G41XA, is manufactured by Elite Semiconductor Memory Technology (ESMT). This is a 2G NAND Flash memory chip used for firmware storage that you could attempt to dump. The datasheet is here:

I'm not sure about that 3rd chip, the markings seem to be EW3048? Nothing comes up for that or similar for me. It could be a LCD controller chip. I see a chip on aliexpress for ew3048 but no description other than "SUHMS"
