Apalis IMX8: imx6q-pcie 5f010000.pcie: PCIe PLL lock timeout

Technical Support
,
1

I’m using the Apalis IMX8 SoC mounted on the Ixora V1.2A carrier board powered by a 12V@2.5A OTS power supply. It has been flashed with a custom image based on tdx-reference-minimal-image. I am monitoring the boot process via a serial cable connected to the UART1 pinouts on the Ixora board.

When powered on, the boot process fails to complete after hitting the error “imx6q-pcie 5f010000.pcie: PCIe PLL lock timeout”

Is there a way to fix this? Is there something that could have caused it? Other boards with this same setup do not encounter this issue.

Thanks!

Hey @ruffle,

We have this error reference on our troubleshooting page, this same serial debug hang-up. This occurs on the first boot with an image w/o Secure boot (on the order of minutes), but subsequently faster on second boot and onward.

Are you able to reboot this module, wait ~a few minutes and see if the module boots and check if second boot is quicker?

When you say this doesn’t occur with other boards and the same setup…Do you mean, the same SoM, carrier board, debugging method, and the same exact image loaded?

Thanks for the suggestion. I tried that and after about 18 minutes the boot process has not moved. I am including the full boot log below in case I missed something else obvious. One thing I do note is that I don’t see the Starting version 250.5+ message or something like it.

When you say this doesn’t occur with other boards and the same setup…Do you mean, the same SoM, carrier board, debugging method, and the same exact image loaded?

Yeah; specifically, after I encountered this issue, I took another Apalis out of its package (had not been used before), put it on the same ixora board with the same power supply, cables, etc, used Tezi to flash the image in the same way, did a reboot, and did not see this issue on that first boot.

5

Hey @ruffle,

Being that the setup + image works with a new Apalis Module. Can you put the non-working module into recovery mode and with our easy installer, reinstall the image.

-Eric

6

Just tried this; no change.

7

@ruffle,

Same error I assume as well?

Would you mind trying again, but instead of your custom image, with the easy installer, pick one of the based reference images to see if the module will boots? This will allow us to either look towards hardware or software for solutions. And also post the boot logs if an option again.

Thanks you,

-Eric

I tried loading the reference image. I don’t think it succeeded but I’m not sure; there is a login prompt but the HDMI output never came up. The serial output was

Hey @ruffle,

From the logs it looks like the module can correctly boot into the default username/password: torizon/torizon. It looks like you used the reference image without the evaluation contains. So it makes sense you do not see an output on the HDMI. Here is the list of images, there is a tab that states “With evaluation containers”

Is there versioning difference between the Apalis IMX8 that works and the one that does not?

-Eric

10

The image that does not work on this unit works on every other unit

11

@ruffle,

Correct, I’m trying to isolate if its a specific hardware version of the IMX8 could be the source of error.

As an example: Are all modules the same Apalis IMX8 … [V1.1A] or possible Apalis IMX8 … [V1.1E]

There is usually, if not peeled off a sticker on the module that will say. Or with a BSP 6 Torizon installed you can get from the output sudo tdx-info

-Eric

12

They both have those stickers and both say V1.1D.

13

I think that the most likely scenario here is that I made a mistake handling the one that does not currently work, and it has become damaged in some way. I was hoping that there might be a clue about what I did wrong or what its condition is.

14

@ruffle,

Given the identical modules, and same hardware, I believe it is best to go down the path of an RMA.

To setup an RMA with us please see the following link for instructions, it will have you fill out a form.

Then you can ship this to our offices at the following address:
