AM335x building the Linux SDK

Bailin Cao

Hello there,

I am in the middle to build am335x SDK under Linux using MACHINE=am335x-evm bitbake arago-core-tisdk-image. To my surprise, the building process started 6 hours and it just finished about 1/5. Can anyone tell me if there is anything wrong with it? Why does it take so long to build it?

I just noticed that there are two versions of SDK,

ti-processor-sdk-linux-am335x-evm-03.00.00.04-Linux-x86-Install.bin

and ti-processor-sdk-linux-rt-am335x-evm-03.00.00.04-Linux-x86-Install.bin

I think that the later is the real time version. Is there any documentation about their differences?

I have started MACHINE=am335x-evm bitbake arago-core-tisdk-image and have to wait for days to let it finish. Can I run "MACHINE=am335x-evm ARAGO_RT_ENABLE=1 bitbake arago-core-tisdk-image" after "MACHINE=am335x-evm bitbake arago-core-tisdk-image" finishes? Or Should I interrupt " MACHINE=am335x-evm bitbake arago-core-tisdk-image" and start "MACHINE=am335x-evm ARAGO_RT_ENABLE=1 bitbake arago-core-tisdk-image" straightaway?

Many thanks

Hello Bailin,

Depending on your CPU/RAM/HDD configuration or if you are building over virtual machine it is expected the building to take a long time.

Check this thread out. You can find a document about rt here.
e2e.ti.com/.../1781655

You can run
"MACHINE=am335x-evm ARAGO_RT_ENABLE=1 bitbake arago-core-tisdk-image"
after "MACHINE=am335x-evm bitbake arago-core-tisdk-image"
but sometimes it fails during the linking stage due to the old temporary and cached object files. The same applies to the interrupting. In these cases you can clean the failed recipe along with the sstate and restart the compilation.

MACHINE=am335x-evm bitbake <failed recipe> -c clean
MACHINE=am335x-evm bitbake <failed recipe> -c cleansstate

Best regards,
Kemal

Hi Kemal,

Thank you very much indeed for your reply.

Please tell me what the difference between building the SDK and installing the SDK?

Bet regards,

Bailin

When you install the SDK you get kernel, U-Boot sources and precompiled rootfs tarball and you can rebuild the kernel and U-Boot. When you build the SDK you download and build kernel, U-Boot and all the rootfs components.

Thanks. There are procedures to build the SDK. I believe that installing the SDK will be a lot quicker. Does "./ti-processor-sdk-linux-[platformName]-evm-xx.xx.xx.xx-Linux-x86-Install.bin" compile the kernel and U-Boot, and then install the kernel, U-Boot and pre-compiled rootfs? Best regards, Bailin

Yes, installing the processor SDK and rebuilding the U-Boot and kernel is the fastest approach. You can find the installation and build steps described here and here.

Hi Kemal,

I failed to install RT AM335x SDK. Please see the attached file for more details. Please advise me what I should do next. Should I start from scratch?

Many thanks and kind regards,

It fails because of this error:
Exception: OSError: [Errno 2] No such file or directory: '/home/bailin/ti/tisdk/build/arago-tmp-external-linaro-toolchain/sysroots/am335x-evm/pkgdata/runtime-reverse/kernel-4.4.12-g3639bea54a'
Please, check why this happened.
