Compiling uImage with all linux modules

yusufalti333 — Wed, 13 Nov 2019 08:38:14 GMT

Hello,

I am trying to compile a new kernel obtained from GitHub - qoriq-open-source/linux (version 4.9) for t1042d4rdb-64b. using Yocto.

I followed the steps;

1) bitbake virtual/kernel -c cleansstate

2) bitbake virtual/kernel -c patch

3) replacing git folder with my new kernels source code (GitHub - qoriq-open-source/linux )

4) make ARCH=powerpc menuconfig

5) bitbake virtual/kernel

Result is, new kernel has compiled successfully but uImage does not contain the drivers I need. There is only 4 drivers in new kernel (deploy/images/t1042d4rdb-64b/rootfs.tar.gz) which is "hid" ,"input", "misc" and "staging". There are lots of driver folders in linux kernel 4.9 such as gpio,gpu,bluetooth, connector and so on..

Question is, how can I import the drivers I need to new uImage and put them into board ?

4) bitbake virtual/kernel -c configure

Is this the step where I enable/disable the drivers I choose ?

and also

5) make ARCH=powerpc menuconfig

Is this step enough to compile kernel with desired configurations for ppc 5500 ?

4) bitbake virtual/kernel -c configure

Configure Linux Kernel with default Linux Kernel configuration file.

5) make ARCH=powerpc menuconfig

Please configure Linux Kernel according to your desired configuration based on the default Linux Kernel configuration.
