Hello

My environment is i.MX6Q and Android 4.4.2.

I want to build fw_printenv but get stuck,and this is my steps:

l@workspace-All-Series:~/android-4.4.2_sdi_in/bootable/bootloader/uboot-imx$ make distclean

l@workspace-All-Series:~/android-4.4.2_sdi_in/bootable/bootloader/uboot-imx$ make mx6q_sabresd_android_config

Configuring for mx6q_sabresd_android board...

l@workspace-All-Series:~/android-4.4.2_sdi_in/bootable/bootloader/uboot-imx$ export ARCH=arm

l@workspace-All-Series:~/android-4.4.2_sdi_in/bootable/bootloader/uboot-imx$ export CROSS_COMPILE=~/android-4.4.2_sdi_in/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

l@workspace-All-Series:~/android-4.4.2_sdi_in/bootable/bootloader/uboot-imx$ make env

make -C tools/env all MTD_VERSION= || exit 1

Thank You

use another cross compile "arm-fsl-linux-gnueabi-" is OK, build cmd like below:

$ make mx6qsabresd_defconfig
$ make CROSS_COMPILE=/opt/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- env

I also meet this question, my step is like below:

Is there something wrong in this uboot source code?

use another cross compile "arm-fsl-linux-gnueabi-" is OK, new build cmd like below:

$ make mx6sxsabresd_defconfig
$ make CROSS_COMPILE=/opt/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- env

but why pre toolchain which build from yocto project 4.1.15-2.0.0ga is not OK?

build cmd like below:

$ bitbake meta-toolchain

or

$ bitbake meta-toolchain-qt5

Dear Qiulong Li:

you can compiled fw_printenv with gcc -static option.

eg:

modify $(UBOOT_PATH_TOP)/tools/env/Makefile

pastedImage_1.png

what's more,you should use linux-gnueabi- not for android  provied prebuilts/gcc/linux-x86/arm/arm-linux-androideabi.

eg:

export ARCH=arm

export CROSS_COMPILE=/opt/Embedsky/tq-linaro-toolchain/bin/arm-none-linux-gnueabi-

modify $(UBOOT_PATH_TOP)/tools/env/Makefile

make env

Hi Qiulong

these are special uboot utilities and its support/building may depend on uboot version.

Please read about its usage on uboot wiki:

HowCanIAccessUBootEnvironmentVariablesInLinux < DULG < DENX

and post possible questions on uboot mail list

U-Boot Info Page

For android 4.4.2 uboot  building it may be useful to look at attached Porting Guide sect.1.2.1

Preparing the Code

Best regards

Hi igor

Thanks for your reply.

My u-boot's version is v2009.08.

The attach file you give me tells me how to  Preparing the Code,I have read and I'm sure my environment is OK,because I can build u-boot.

I can use the follow cmd to build u-boot

make distclean

make mx6q_sabresd_android_config

export ARCH=arm

export CROSS_COMPILE=~/android-4.4.2_sdi_in/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

make

But I can't use the follow cmd to make make fw_printenv

make distclean

make mx6q_sabresd_android_config

export ARCH=arm

export CROSS_COMPILE=~/android-4.4.2_sdi_in/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

make env

Thanks

Qiulong Li
