Hi Noor,

I just came across your post for a booting error with VxWorks (https://epics.anl.gov/tech-talk/2022/msg01756.php), and we just started encountering the same error on our system.

I was wondering if you had any success on resolving this? Any advice or tips would be greatly appreciated!


If I understand right that you're seeing the error message "WARNING:Bootline longer than BOOT_LINE_SIZE (255 bytes). Not saved to NVRAM." then the reason is described in the error message itself — VxWorks CPUs only have a small amount of NVRAM available for storing the boot parameters, and the error is telling you that the parameters you are trying to set need more storage than is available to hold them.

In the case asked on tech-talk the user may have copy/pasted extraneous characters into their parameter strings, and deleting them helped resolve the error for them. If that isn't the case with your settings you will have to work out how to shorten one or more of the file paths in those parameters, until you can get them all to fit. Soft links on the server may be one way to do that.

HTH,
