Hi Deepak,
Sorry for not being clear the first time around. My objective is to write a program with which i will be able to access the u-boot version.
Form Linux that is I guess. If you have CONFIG_VERSION_VARIABLE defined in your U-Boot configuration, then according to README (see, documentation can help sometimes):
- U-Boot Version: CONFIG_VERSION_VARIABLE If this variable is defined, an environment variable named "ver" is created by U-Boot showing the U-Boot version as printed by the "version" command. This variable is readonly.
This variable will also end up in the saved environment, (after at least one saveenv), so you could use the "standard" fw_printenv tools in tools/env/.
Also i would like to add a new parameter to the bootstrap which would specify the bootstrap version.(which i want to according to changes i make to bootstrap)
You;d have to define what "a bootstrap" is for you.
i assume that for this i will have to write a version string to the nand flash and then try to access it for the linux kernel....but thats just an idea...have no clue how to....
Well if "bootstrap" is e.g. a combination of a U-Boot version + a way to boot Linux, you could simply pass an linux commandline option which is not evaluated by the kernel itself, say "bootstrap=..". In Linux you can use /proc/cmdline to read the command line and find your switch, voila.
