[U-Boot] Can i pass pass an environmental variable or argument from command line to build u-boot?

[U-Boot] Can i pass pass an environmental variable or argument from command line to build u-boot?

[harsha kiran]

Hi !

For our project, we are trying to build the Bootloader with a Software
partnumber. and i want it to be displayed on the first U-boot print..


U-Boot 2014.07 (Nov 05 2014 - 16:27:50) PN#12345678-001

I2C:   ready
DRAM:  256 MiB
WARNING: Caches not enabled
MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1
Using default environment

I was able to do this by adding the following in the boards.cfg file..

Active  arm         armv7          am33xx      ti             
am335x_abb_uboot    am335x_abb_uboot_npa_dev				
am335x_abb_uboot:SERIAL4,CONS_INDEX=4,NPA_DEV,IDENT_STRING="PN#12345678-001" 

But i want to pass the IDENT_STRING from the command line to build the
u-boot..the command i use is 

sudo make ARCH=arm
CROSS_COMPILE=/abb/compilers/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin/arm-linux-gnueabihf-
-j8 -s am335x_abb_uboot_npa_dev_config

is there a way i can pass this argument while building the u-boot? 

Thanks,
Harsha

Upgrade to current mainline and you can use CONFIG_LOCALVERSION for what
you want.

[U-Boot] Can i pass pass an environmental variable or argument from command line to build u-boot?

[harsha kiran]

Thanks Rini,

We have freeze the code base of bootloader for 2014-07 main line.

What can be another alternate approach? i was looking at the make file and i
see that they take everything before _config and is sorted to find all the
right pieces from boards.cfg file

%_config:: outputmakefile
	@$(MKCONFIG) -A $(@:_config=)

i was thinking to add something which can parse the Partnumber after the
_config..i am not sure if its a good approach..

Thanks,
Harsha

Why don't you save your favorite version string into a file "localversion"?
This feature is available in v2014.07.
