BSP Porting Guide -Errors while compiling uboot-sh

[srinivasaporam]

Hi,

We have got a customized board which has been designed based Wandboard -dual.

While porting the BSP we are follwoinf the Yocto project's "BSP porting guide.pdf" according to which we have done the following steps:

1. We came to know that working directory for uboot is:

/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git

2. We have prepared the code for uboot by

2.1 Copy the board directory, as shown below:

$cp -R board/wandboard board/wandboard_dual_lpddr2

2.2 copy the existing configuration file (.h file) for the custom board

$cp include/configs/wandboard.h include/configs/wandboard_dual_lpddr2.h

2.3 Create one entry in <UBOOT_DIR>/boards.cfg for the new -based configuration.

We have created following entry :

Active  arm	armv7	mx6	-	wandboard	wandboard_dual_lpddr2
wandboard:IMX_CONFIG=board/wandboard_dual_lpddr2/wandboard_dual_lpddr2.cfg,MX6DL,DDR_MB=1024

2.4 Renamed the file /board/wandboard_dual_lpddr2/wandboard.c to /board/wandboard_dual_lpddr2/wandboard_dual_lpddr2.c

2.5 Changed the line

COBJS:= wandboard.o    to

obj-y := wandboard_dual_lpddr2.o

3. Created a shell script under <UBOOT_DIR> named build_u-boot.sh.

The file contents are as follows:

#!/bin/bash

export ARCH=arm

export CROSS_COMPILE=/home/srinivas/fsl-community-bsp/build/tmp/sysroots/x86_64-linux/usr/bin/cortexa9hf-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi-

make distclean;

make wandboard_dual_lpddr2_config

make

4. Compiled U-Boot by using $bash ./build_u-boot.sh which is giving so many errors

the errors are as follows:

/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git/include/configs/wandboard_dual_lpddr2.h:115:13: error: expected '}' before 'CONFIG_DEFAULT_FDT_FILE'

  "fdt_file="CONFIG_DEFAULT_FDT_FILE"\0" \

             ^

/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git/include/env_default.h:122:2: note: in expansion of macro 'CONFIG_EXTRA_ENV_SETTINGS'

  CONFIG_EXTRA_ENV_SETTINGS

  ^

make[1]: *** [env_common.o] Error 1

make[1]: Leaving directory `/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git/common'

make: *** [common/libcommon.o] Error 2

So after going through errors i have modified the /git/include/configs/wandboard_dual_lpddr2.h where "fdt_file="CONFIG_DEFAULT_FDT_FILE"\0" \ is been changed to "fdt_file=CONFIG_DEFAULT_FDT_FILE\0" \ the same way same variable is changed in /git/board/wandboard_dual_lpddr2/wandboard_dual_lpddr2.cfg

now when i run the command for compiling uboot: $bash ./build_u-boot.sh following errors are coming

/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git/include/asm/arch/mx6-pins.h:18:2: error: #error "Please select cpu"

#error "Please select cpu"

  ^

make[1]: *** No rule to make target `.depend', needed by `libwandboard.o'.  Stop.

make[1]: Leaving directory `/home/srinivas/fsl-community-bsp/build/tmp/work/wandboard_dual-poky-linux-gnueabi/u-boot-fslc/v2013.10-r0/git/board/wandboard'

make: *** [board/wandboard/libwandboard.o] Error 2

what is problem. Why uboot is not compiling. after compilation only, we can customize it. how to resolve this issue.

Hi,

Please try the next configuration:

Active  arm	armv7	mx6	-	wandboard_dual_lpddr2	wandboard_dual_lpddr2
wandboard:IMX_CONFIG=board/wandboard_dual_lpddr2/wandboard_dual_lpddr2.cfg,MX6DL,DDR_MB=1024

Best Regards,

Alejandro

Hi,

after trying your suggestions also, we have got the following errors:

Did you try to build the original target reference first?

Please try that first and make sure do not moidfy the functionality of the code when porting U-boot first.  Just make sure that you are including the correct .h files in the .c ones.
