Booting up Ultrazed-EG dev board

1 Nov 2022

Hello all,

I am not able to boot up the board even after following the steps exactly given in the manual. It seems that the board is not drawing any current as the fan which I am mounting on it is also not powering up and the PS red LED is also not glowing. Apart from that, I am not able to find the "rootfs.cpio.gz" file in the downloads section of AVNET. Any leads on this would be greatly appreciated.

Thank you

Check the booting mode configuration: DIP setting as below

I used a carrier board with Ultrazed-EG before. So please read the hardware user guide for your trouble-shooting:

Good luck!

No idea about that. Maybe some other members who have worked with the Ultrazed-EG may help you out

Thanks rsjawale24. Do you happen to know anything about the "rootfs.cpio.gz" file ?

I would suggest to use a digital multimeter to check if the board is getting the supply or not. Maybe some power supply IC has failed or shorted. You can identify the power supply area on the PCB by inspection method. Just follow the path from the power input side. First check the voltage at the power input.
