I am trying to bring up a custom board and I keep getting a Kernel oops!

Specifically this message before a stack/register dump:

kernel BUG at /dvs/git/dirty/git-master_linux/kernel/nvidia/drivers/platform/tegra/tegra_cbb.c:839!

I am using the standard image from the Jetson AGX on my custom board and have tried to build other images using my pinmux config (without success of flashing it). I do not have U501 present and am working on getting that resolved, however the design guide says that this is not needed.

I woul dlike a list of what all these panic modes are (eg please publish tegra_vbb.c) so that we can diagnose our own hardware.

What would be useful is a very basic ‘kernel’ image that has no peripherals and just uses UART as the terminal. This way we can see if the CPU and other system stuff is running.

Thanks,

Here is a snipped of the log if this helps. I’m at the stage of hardware bring up and I need to know the root cause of this kernel oops. Thanks.

I’m welsh too !
I’m going to move this post to a different category, the team there will be in a better position to help you.

Thanks. Diolch yn fawr !! (I don’t speak Welsh but grew up there).

Remove “quiet” in your /boot/extlinux/extlinux.conf and flash your board again to enable full logs.

And I think this is still related to hardware design. You may clarify what is added on your board in comparison with our developer kit.

Or you can just test this module on developer kit first to make sure it is working fine.

This is basically a cut down version of your carrier board. The module works fine in your carrier board. I am trying to get it to boot in our custom board and I can’t find out what it’s failing on. If I could find out what is causing a spurious interrupt or incorrect state I might be able to isolate the problem.

The only thing that has changed on out custom board is the PCIe interfaces. All other peripherals are removed. USB, HDMI, Etc removed. I have kept the M2/M interface and SD interface. Also none of these devices are populated: U513 is not present. U501 is now present and has a clone of the contents of your Carrier board. I still see the same error whether booting from EMMC or SD. I’m pretty sure it’s related to the hardware design but I don’t know what to look at since the error is cryptic! - I will try as you suggest. The module has power. I am looking at the UART3 debug terminal for the status. I see that I2C 0x50 times out and this is apparently internal to the module. I don’t understand why this is as I don’t have anything on that I2C bus. I have an EEPROM at 0x56 as per your original schematics.

Thanks. Log of SD boot up below.

  1. Just let you know, it would be better to attach your log as text file here. Otherwise if you keep pasting more and more logs directly, it will be hard to read this post or using search function.

  2. It seems that every time the system gots cpu error, the last driver is ufs tegra. Do you have ufs on your board design? If not, how about disabling it from device tree first?

Thanks Wayne.

So in all reality I’m not that familiar with the whole device tree build process for custom hardware. I’m the hardware guy and I’m kind of running blind as I have no software support currently (maybe you can suggest a consultant ?). If there is a detailed step by step process on how to map IO’s correctly in the config tree and build an image + flash that would be very helpful. I have built the *.dtsi files and have basically been mucking around trying to figure out how to build things. However there’s a lot of stuff in there that I don’t know or understand.

What would be helpful would be a command line step-by-step guide for myself and people like me who are bringing up new hardware.

Cheers.

Just to add to this my process is: build, try and program on an AGX carrier board and them move the module to our custom hardware.
