 | If your board has some NVRAM memory, it would be a good idea to use it for bootloader purposes. After writing a module for our NVRAM memory (out of scope for this paper), we modified the bootloader, so that the kernel command-line, and MAC address were saved in NVRAM. When the bootloader starts, it checks NVRAM and if it is initialized (by a certain magic number), the bootloader uses the command line written there. Otherwise, the bootloader reverts to a default command line, allowing the user to edit it. |
