DLPDLCR230NPEVM: The LEDs on the Board are not coming back on

Tool/software:

Hi team,

Since I enabled the LEDs the system has not produced light.

Before plugging in the EVM I verified the Power supply etc by starting the system up without enabling the PI controls. So that should not be the issue.

I have been stepping through each setting required to operate the board. Ie verifying all GPIO pins are set correctly per the User manual dlpu103b.

I successfully updated the firmware on the system and I am able to communicate with the different subcomponents.

I am running Raspberry Pi OS (Legacy) Kernel 6.1 and Debian version 11. 

I am able to communicate with boards etc just get the LED's back on? 

Any suggestions welcome.

    Hello User,

    Since I enabled the LEDs the system has not produced light.

    The LEDs should come on automatically and not require a user to send a command. When the EVM was first received and connected to power did the LEDs come on?

    What is the status of the HOST_IRQ and D_DONE LEDs on the board?

    Best,

    John
