Linux/TMDSICE3359: Boot time optimization

Hi!

From your content I came to link http://arago-project.org/wiki/index.php/Setting_Up_Build_Environment

I have made all operations to:

$ cd tisdk
$ ./oe-layertool-setup.sh -f configs/arago-rocko-config.txt
$ cd build
$ . conf/setenv
$ TOOLCHAIN_PATH=$HOME/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf MACHINE=am335x-evm bitbake $HOME/tisdk/sources/oe-core/meta/recipes-core/images/core-image-minimal

The result is 1 error:

I hope you tell me about this error (or it is unimportant).

This link provide old info that might be not up to date. Please refer to the below links for customizing the default TI PSDK:

Note also that we have minimal rootfs that you might use to boot faster, check below pointers:

In 1.2.2.2. Build Steps:
the command:
./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-05.01.00.11-config.txt

create the directory:
tisdk/sources/meta-processor-sdk

the shows an errors:

I would suggest you to open new e2e thread regarding errors during Yocto Layer configuration.

Let me know if you have any further questions regarding boot time optimization in u-boot or linux kernel.

Regards,
Pavel

Pavel Botev,

ok, I'll open the new e2e thread.
