HI!

I updated mender to 1.7.0 thud and meta-freescale to thud for my iMX6ULL evk board. Also, I added these two lines in local.conf:

MENDER_FEATURES_ENABLE_append = " mender-uboot mender-image-sd"
MENDER_FEATURES_DISABLE_append = " mender-grub mender-image-uefi"

However I cannot build with mender.

First I updated mender patches "0003-Integration-of-Mender-boot-code-into-U-Boot.patch" and "0004-Disable-CONFIG_BOOTCOMMAND-and-enable-CONFIG_MENDER_.patch" to apply them to u-boot 2017.03 thud. The cose is the same, but I simply regenerated patch files because weren't apply.

However I cannot build yet. The error is:

HI!

I updated mender to 1.7.0 thud and meta-freescale to thud for my iMX6ULL evk board. Also, I added these two lines in local.conf:

MENDER_FEATURES_ENABLE_append = " mender-uboot mender-image-sd"
MENDER_FEATURES_DISABLE_append = " mender-grub mender-image-uefi"

However I cannot build with mender.

First I updated mender patches "0003-Integration-of-Mender-boot-code-into-U-Boot.patch" and "0004-Disable-CONFIG_BOOTCOMMAND-and-enable-CONFIG_MENDER_.patch" to apply them to u-boot 2017.03 thud. The cose is the same, but I simply regenerated patch files because weren't apply.

However I cannot build yet. The error is:

You probably need this patch [1], could you try applying it as well to your 2017.03 U-boot and check back.

Hi, thank you for the answer.

I applied your patch but it isn't working yet. The issue seems the same.

The patch is applied successfully in both work/..../u-boot-imx/..../git/tools/ and work/..../u-boot-imx/..../git/tools/env

Error message is:
