After PROJ_ON pulls high, the RESETZ indicator light keeps on and off periodically， connected DMD and LEDs or not is the same phenomenon. Please help, thanks.

Hello Sun,

Welcome to the E2E forum.

Are you experiencing this issue with an EVM or a custom design?

How frequently is this occurring after the PROJ_ON switch is in the on position? Every 30 seconds or some other interval?

Can you connect with the Light Control GUI with your device?

Regards,

John

Hello Sun,

Could you please confirm whether this is new EVM you recently bought and facing this issue or is it something that you are observing after using a period of time

Regards,
