VxWorks: Why bootline can't be changed？

Question

I am trying to revise the bootline of VxWorks by running the “bootChange” command in shell.

I can successfully see the change right after i run this command by checking “version” command, but when i really try rebooting the VxWork, the changes wasn't applied.

So i am confused and hope i can get some insight of why such change doesn't work.

By the way there does have a flash as the main storage in my equipment, and i believe the bootrom image which contains the booline was burned in that flash.

And i have checked that the flash wasn't mounted in VxWorks by running “devs” command.

Seems like your question is missing your commands and your configuration setup as such we can't help you and this question is going to be closed — Tarick Welling, Apr 28 '20 at 08:57

Is your system booting with U-Boot or with a VxWorks Bootrom? You might confirm which VxWorks version is used.

If you have a bootrom, try the to change the boot line parameter from the bootrom context by using the command "c". You can also pass the full boot line parameter preceded with "$" to tell to the boron to use this boot line instead.

Note: devs in VxWorks would not display the flash/nvram being used for storing the boot line parameter. You might check the file target.nr, target.ref in the BSP directory.
