What am I missing here to boot the kernel and mount root file system for AVNET MicroZed board - how to debug here?

dexterous.me82
dexterous.me82 over 5 years ago

I have an AVNET microzed board  PB-AES-Z7MB-7Z010-G board.

It just says "Starting kernel ..." and I don't see anything further.

How do I see all the logs? I don't know why it is stopped like - "Starting Kernel..."?

 

From where this print is coming and why I can't see any more logs?

 

Here are the logs -

    HI there,

     

    Are you using the PetaLinux image we created, or the Yocto image you mentioned in another thread?

    The boot messages are buffered, so it is sometimes very difficult to tell where *exactly* the kernel has hung during boot.  One thing I can think of is to make sure the "partition" size definitions in the u-boot config (for the kernel, ramdisk, dtb, etc.) are at least as large as the kernel, ramdisk, and dtb files.  If you have a tftp server you could try pausing u-boot and boot the system via tftpboot instead.

     

    Or, better yet, download and install a known-good PetaLinux BSP:
    MicroZed

    Can you please point out to me to building  PetaLinux  for my AVNET MicroZEd board?
