Hi!
I builded a Image with following instruction
> **[GitHub - SolidRun/lx2160a\_build: Scripts to build basic images for LX2160A COM...](https://github.com/SolidRun/lx2160a_build/tree/master)**
>
> master
It’s give me two images:
lx2160acex7\_2000\_700\_3200\_LX2162A\_CLEARFOG\_18\_9\_0-3fbd680.img lx2160acex7\_xspi\_2000\_700\_3200\_LX2162A\_CLEARFOG\_18\_9\_0-3fbd680.img
I choose the upper for dd to uSD Card with:
```auto
sudo dd if=lx2160acex7_2000_700_3200_LX2162A_CLEARFOG_18_9_0-3fbd680.img of=/dev/sdX bs=4M conv=fdatasync status=progress
```
I do following postion on the buttons
Plug in the power
Nothing happen only blinks a red led
Why?

Is there a limition of size for uSD card?

You seem to have built images for our LX2162a based SOM platforms. What command are you using to build the images? You can test images from here, [SolidRun Images](https://images.solid-run.com/LX2k/lx2160a_build/20240731-2a7ab21) Make sure to download the ones that don’t have LX2162A\_CLEARFOG in the name.

Thanks for reply.
I build from this description.

The command is following which I used
```auto
docker run --rm -i -t -v "$PWD":/work lx2160a_build -u $(id -u) -g $(id -g)
```
I will try a pre-builded image without CLEARFOG and will give you answer how it’s working or not

No isn’t working. It goes mad. The device is blinking with red and green leds like some police lights.
I use a 128 GB Samsung PRO uSD card.

Have I to flash the SPI too? I have flashed the SPI with following
```auto
lx2160acex7_xspi_2000_700_3200_LX2162A_CLEARFOG_18_9_0-3fbd680.img
```
and i didn’t change it for the this image. [lx2160acex7\_2000\_700\_3200\_8\_5\_2-2a7ab21.img.xz](https://solid-run-images.sos-de-fra-1.exo.io/LX2k/lx2160a_build/20240731-2a7ab21/lx2160acex7_2000_700_3200_8_5_2-2a7ab21.img.xz)

if the ethernet lights are flashing then the security core can’t read the RCW from the uSDHC card. I would recommend trying another card. It is possible that you have a bad write on your card, so sometimes writing all zero’s to the first 16MB’s of the card can help, before flashing a new firmware.
