Make error while adding support for custom board in u-boot.

[sujay1]

I have a custom board based on ls1021atwr and I've added a layer in u-boot (u-boot 2016) board file as:

u-boot/git/board/my_vendor/board_name/

I copied the .c file, Makefile and kconfig and placed in this folder.

I then followed all steps mentioned in the answer to this thread:

https://community.nxp.com/thread/380164#comment-590485 

but while building with bitbake -C compile virtual/bootloader I get:

| make[1]: *** No rule to make target `board/vendor/board_name/board_name.o', needed by `board/vendor/board_name/built-in.o'. Stop.
| make: *** [board/vendor/board_name] Error 2
| make: *** Waiting for unfinished jobs....

Can anyone tell me what I'm missing?

I had incorrectly changed soc field in board/vendor/Kconfig.

Setting it solved the issue

1. In Yocto environment please create meta-freescale/conf/machine/<customboard>.conf.

2. $ source setup-env -m <customboard>

3. $ bitbake u-boot -c cleansstate

    $ bitbake u-boot -c patch

    Go to folder build_<customboard>/tmp/work/<customboard>-fsl-linux/u-boot-qoriq/2018.09+fslgit-r0/git/.

4 . Please create folder board/freescale/<customboard> for your target board, please put Makefile, Kconfig and .c file in this folder.

5. Please create header file include/configs/<customerboard>.h based on ls1021atwr.h.

6. Please add configs/<customboard>_nor_defconfig based on ls1021atwr_nor_defconfig.

7. Go to folder build_<customboard>, execute "bitbake u-boot -c compile", if failed go to step 4 to continue to modify u-boot source code.

8. $bitbake u-boot
