Coming out of the Asleep mode in LS1028ARDB

sameer_chouksey · ‎03-10-2020

Hello everyone,

I am using LS1028ARDB switch for some applications. The switch is working fine except sometimes when it goes to asleep mode. The D25 LED will turn ON and will be on all the time. I tried resetting and restarting the device but still the device is not coming out of the asleep mode.

Can someone please help me with the procedure to bring the device out of the asleep mode?

Thanks & Regards,

Sameer

Please provide U-Boot and Linux booting log as textual attachment.

I am not able to access the board when in SD boot. As soon as I power it on LED D25 turns yellow and the power button SW1 also turns yellow. I don't see any thing on the teraterm.

The only time D25 turns off and the power button SW1 is not yellow is when I change SW2 to eMMC boot mode. I am attaching the logs when it is in eMMC boot.

Regards,

Sameer
