How to recompile when using ltib for compiling u-boot and kernel

[jayakumar2]

Hi,

I'm using L3.0.35_4.1.0_130816_source ltib to build for the MX6SL evaluation kit. I noticed that each time I make a change to u-boot takes quite a bit of time. Eg: I just made a change to a printf in board/freescale/mx6sl_evk/mx6sl_evk.c , and I recompiled by doing:

lucid@ubuntu:~/6sl/ltib/rpm/BUILD/u-boot-2009.08$ ( cd /home/lucid/6sl/ltib/ ; ./ltib -m scbuild -p u-boot )

and that kicks off a full rebuild as shown below part A. That takes a lot longer than desirable. I tried to escape this by doing:

( echo makeuboot ; cd /home/lucid/6sl/ltib/rpm/BUILD/u-boot-2009.08/ && PATH=/home/lucid/6sl/ltib/bin:/opt/freescale/ltib/usr/spoof:/home/lucid/6sl/ltib/bin:/opt/freescale/ltib/usr/bin:/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin make CROSS_COMPILE=arm-none-linux-gnueabi- )

but this seems to work only the first few times. After that, it gets this weird error:

Generating include/autoconf.mk

fatal: cannot describe '9b3adb2c5d3015ff4d14b56623b9edbc4c698105'

It is much worse for rebuilding the kernel. Every time I build it recompiles everything even though I changed just a single line in board/freescale/mx6sl_evk/mx6sl_evk.c . Eg:

Is there a way I can avoid all of this?

Jaya,

The simple way to go to the source directory and use "make" command. Before run "make" just set the CROSS_COMPILE

export ARCH=arm

export CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi-

If you are open to migrate to Yocto Project, you can use the FSL Community BSP as it provides support for i.MX6SL EVK board and provides a newer version of U-Boot (2013.04-fsl and 2013.10).

[jayakumar2]

Thanks Otavio. Yes, I like Yocto/OE based recipes and intend to migrate to it in the longer term. I'm glad to hear that there's a community behind it. However, in the short term, looks like I have to stay with ltib. Hopefully I'll find a way to recompile faster than doing scbuild each time. Thanks.

[OtavioSalvador]

Jaya, alright.

Just bear on mind that 3.0.35-4.1.0 was the last LTIB release and 3.10.17-1.0.0 (for Yocto Project) is in beta already.

Anyway... good luck with the project.
