iMX51 EVK u-boot build question

[brianlin]

Hi all,

I download [imx-android-r10.4_bundle_BSP.tar.gz] from Freescale website and follow its user guide [i.MX Android R10.4 User Guide].

I am trying to build a u-boot image by myself. So I follow all the steps of source code download like below.

$ cd myandroid/bootable/bootloader
$ git clone git://git.denx.de/u-boot.git uboot-imx

After [uboot-imx] folder download finish. And finish apply R10.4 release patch.

Then I try to follow below steps and caused an Error message below. I found there is no string [mx51_bbg_android_config] in makefile. and related mx51_bbg_android file such as mx51_bbg_android.h in [uboot-imx] folder. Which steps I missed? Please help me. Thank you.

$ cd ~/myandroid/bootable/bootloader/uboot-imx   
$ export ARCH=arm
$ export CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.3.1/bin/arm-eabi-
Command to build for i.MX51 BBG board is:
$ make distclean
$ make mx51_bbg_android_config
$ make

Error message:

make: *** No rule to make target `mx51_bbg_android_config'.  Stop.

The DENX U-Boot is the mainline U-Boot and the MX50EVK board target is different.

Please use:

make mx51evk_config

[brianlin]

Many Thanks! It works.

Another question, what name I should put for Kernel build. Seems below name is incorrect.

make imx5_android_defconfig

[brianlin]

Sorry, I found out the correct name.

$ make mx51_defconfig

Now I am checking how to build Android image with correct product name.

$lunch imx51_bbg-user

Error message:

build/core/product_config.mk:203: *** No matches for product "imx51_bbg".  Stop.

** Don't have a product spec for: 'imx51_bbg'

** Do you have the right repo manifest?

I am not an Android guy so I won't be able to help here.

Thank you Otavio. But here I face a boot problem. After I build u-boot.bin and uImage. I flash in my SD card and try to boot MX51 EVK board. It cannot boot-up. I don't know what's wrong. Can you give me some advice?

Here is my SD card partition status:

Device Boot	Start	End	Blocks  Id  System
/dev/sdb1	19532	13949064	6964766+  83  Linux
/dev/sdb2	13949065	14925664	488300  83  Linux

Flash u-boot-no-padding.bin command:

$ sudo dd if=u-boot-no-padding.bin of=/dev/sdb bs=1K seek=1; sync

Result:

What is the log, in serial console?

[brianlin]

Hi,

Serial console showing like this when I press power bottom up. (when my finger leave the bottom). Seems no boot start. Is it my partition wrong? or something else? Thanks.

It could well be it; I'd test the Yocto built image as I know it works.

[brianlin]

Hi, I follow below link. It works.

i.MX51 EVK U-boot

Double check the u-boot repo. I don’t have the documentation at hand, but it can be this git://git.freescale.com/imx/uboot-imx.git
