Hi,

Im getting the following error while compiling the u-boot source code for t4240rdb-64

Use the following command sequence for install u-boot source code:

bitbake -c cleansstate u-boot

bitbake -c patch u-boot // source of the u-boot

The following command sequence was used for u-boot compiling for the T4240rdb board.

1. . fsl-setup-env -m t4240rdb
2. bitbake fsl-toolchain
3. $ cd build_<machine>_release/tmp/deploy/sdk
4. $ ./fsl-qoriq-glibc-x86_64-ppce6500-toolchain-2.0.sh

                               in the folloing folder:

QorIQ-SDK-V2.0-20160527-yocto/build_t4240rdb/tmp/deploy/sdk

5. source environment-setup-ppce6500-fsl-linux

in the following folder:

/opt/fsl-qoriq/2.0

6. Go to the following folder:

/QorIQ-SDK-V2.0-20160527-yocto/build_t4240rdb/tmp/work/t4240rdb-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git

Issue the following commands:

1. a) export ARCH=powerpc
2. b) make ARCH=powerpc CROSS_COMPILE=file:///opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin/powerpc-fsl-linux-gnuspe  T4240RDB_defconfig

See the configuration files in the /configs folder.

1. c) make
