Clean/Rebuild target using bitbake

dhavalvadhar — Wed, 19 Aug 2015 09:21:19 GMT

Hi,

I want to clean the binaries generated using 'bitbake' command and rebuild the following two targets:

1. I ran command 'bitbake core-image-minimal'. And at the end it will generate few images which will be deployed at "<build dir>/tmp/deploy/images/<target device>/" path. Now next when I run this command it will generate all new images and create appropriate sym-links. But it also kept older images. How can clean this?

2. I ran command 'bitbake imx-test'. It will build the unit tests and then generate the binaries at "<build dir>/tmp/work/<target device>-poky-arm-gnueabi/imx-test/<version>/..." path. Now, after changing one of the source file, I again ran the command 'bitbake imx-test'. But it didn't compile the updated source file and thus didn't generate the binary. How can I achieve this?

I would appreciate if someone can help me understand and resolve this.

Thanks,

Dhaval

Use following command sequence.

bitbake -f -c compile imx-test

bitbake imx-test

Thanks

Hi Saurabh,

Thanks for your quick reply!

1. What about the first question of my post.

2. I have tried the command you have suggested and that works fine. Now I want to add a customized capture application within imx-test and want to build it. For that I put that application in mxc_v4l2_test directory and updated the mxc_v4l2_test/Makefile as follows:

ifeq ($(PLATFORM),$(findstring $(PLATFORM),$(CSI_LIST)))

OBJS += $(OBJDIR)/csi_v4l2_overlay.out \

$(OBJDIR)/mx6s_v4l2_capture.out \

$(OBJDIR)/sampleCapture.out

Then I rebuild the imx-test using same commands. But it is not generating the .out file!! Am I doing something wrong?

Also, how can I build the imx-test using 'make' command i.e. without using 'bitbake'.

Thanks,

Dhaval

For your first post check following.

YOCTO project clean

For your second post.

Use attached folder , put you file as "mxc_test_out.c"

Hi Saurabh,

Thanks for your reply! I was able to build the *.out file using the Makefile, after removing linking of '-lvpu -lipu as I didn't get these libraries. After that I try to run the compiled *.out file on i.MX6. And it is giving me strange error.

Compilation logs:

$ make clean;make

Though this file is exist, it is giving the error 'No such file or direcory'. Not able to understand why?

Please help me here.
