问题
I have a problem configuring the bootrom parameters for my virtual machine VxWorks 5.5.
I want to change the target IP address. I tried modifying the DEFAULT_BOOT_LINE macro in config.h. But, I didn't work. I use printf to check the value of DEFAULT_BOOT_LINE. It didn't changed.
This seems that DEFAULT_BOOT_LINE is defined elsewhere beside config.h and can't be modified. Do you know what the problem is? Is there other methods to change the bootrom parameters?
回答1:
To erase BOOT_LINE_ADRS and get back to DEFAULT_BOOT_LINE,
-> my_boot_line = malloc (8)
-> memset my_boot_line, 0x00, 8
-> memset my_boot_line, 0xff, 4
-> sysNvRamSet my_boot_line, 8, 0 /* This line depends on your BSP. */
To change boot parameters at the bootrom prompt,
[VxWorks Boot] c
To change boot parameters at shell prompt,
-> bootChange /* at the shell prompt */
