Morello board hangs before reaching UEFI at LcdGraphicsOutputDxe.efi

Mostafa Saleh

Hi,

I just started with the Morello board, and after flashing the latest prebuilt on a USB memory,  Linux wouldn't boot to home and hangs at SMP bringup which pointed me to

 Morello: Pre-built images stall at "smp: Bringing up secondary CPUs" 

Then I go the latest firmware prebuilt 

https://git.morello-project.org/morello/board-firmware/-/tree/morello/mainline?ref_type=heads

And flashed it on the SD card as mentioned in 

https://git.morello-project.org/morello/docs/-/blob/morello/mainline/firmware/user-guide.rst#id23

And now I can't reach UEFI boot menu and it hangs as follows:

Please note that I have no screen connected, and when I connect one via HDMI it still hangs with slightly different error

    Hi Mostafa,

    After checking on the shared logs I could see the following in the SCP logs:

    [    0.000000] [PCIe] Powering ON controller...
[    0.004050] [PCIe] Timeout!
[    0.006834] [FWK] Process event ([NOT 17:0]: [ELM 17:0] -> [ELM 34:0]) (-7)
[    0.013758] [CCIX] Powering ON controller...
[    0.018023] [CCIX] Timeout!
[    0.020809] [FWK] Process event ([NOT 17:0]: [ELM 17:0] -> [ELM 34:1]) (-7)


    What I believe that the hang is properly because of the issue with the PCIe controller which has not been turned on as the stage where boot hangs in UEFI is actually followed by the PCIe enumeration and as evident from SCP, the controller is not on so it's in a wait queue, I guess.

    Few things to check from here:
    1. Can you check the power supplies if they are as per the guide?
    2. Any secondary media or any external device connected to the board via PCIe, CCIX or USB interface? If yes, can you please unplug everything and check a nominal boot if that takes you through the UEFI menu?
    3. If available, can you please try the same firmware on any board? We are not facing it currently on any of the other Morello boards.

    Thanks,
    Himanshu
