Hi Nandish SG,

You are asking about the u-boot variable, so you will find that under uboot-imx directory.

For board specific file you can have a look at uboot-imx/board directory. Other environment specific variable can be found in uboot-imx/include/configs/<board>.h and uboot-imx/env directory.

Hi Nandish SG,

Sorry for the inconvenience, can you please make us clear about which source code you want. Like savenev how it works? Or something like below

include/configs/<board.h>

example:

include/configs/mx6sllevk.h

Hi Nandish SG,

Sorry for delayed response.

You can find the source code of uboot command under <u-boot-src>/cmd/ directory.

Let me know in case of any concerns.
