+Compile everything and buildr the rootfs image:

+    ├── flash.bin
+    ├── ddr3*

+Flashing the emmc card image
+==========================
+
+To install the image on on eMMC
+
+  $ sudo uuu -b emmc_all output/images/flash.bin output/images/sdcard.img
+
+
+Preparing the board
+===================
+
+ * Connect a serial line to the board
+ * Power-up the board
+
+
+Booting the board
+=================
+
+By default the bootloader will search for the first valid image, starting

+How to build it
+===============
+
+Configure buildroot:
+
+  $ make bsh_smms2pro_defconfig
+
+Change settings to fit your needs (optional):
+
+  $ make menuconfig
+
+Compile everything and buildr the rootfs image:
+
+  $ make
+
+
+Result of the build
+===================
+
+After building, the output/images directory contains:
+
+  output/images/
+    ├── bl31.bin
+    ├── Image
+    ├── flash.bin
+    ├── ddr3*
+    ├── rootfs.ext2
+    ├── rootfs.ext4 -> rootfs.ext2
+    ├── rootfs.tar
+    ├── sdcard.img
+    ├── u-boot.bin
+    ├── u-boot-nodtb.bin
+    └── u-boot-spl.bin
+
+
+Flashing the emmc card image
+==========================
+
+To install the image on on eMMC
+
+  $ sudo uuu -b emmc_all output/images/flash.bin output/images/sdcard.img
+
+
+Preparing the board
+===================
+
+ * Connect a serial line to the board
+ * Power-up the board
+
+
+Booting the board
+=================
+
+By default the bootloader will search for the first valid image, starting
+with the internal eMMC.

Same here.

You mean the UBOOT_TOOLS* package. I will drop as soon as I have a uboot downloading point in apertis (better the this one)

I think Heiko means BR2_PACKAGE_HOST_IMX_MKIMAGE=y, indeed I've just built successfully the defconfig.

Quoted 7 lines

So I give you a:

Reviewed-by Giulio Benetti <[email protected]>

removing BR2_PACKAGE_HOST_IMX_MKIMAGE=y

and with the promise to bump Linux and U-Boot versions as soon as new versions are released with the goal of removing the -rc1 versions.

Forgotten to mention again, we need Ariel "Tested-by:" before applying.

Regards
