Debian 12 SDK

AngelF — Mon, 23 Sep 2024 08:38:49 GMT

Hello,

We have read that NXP has released a new version based on Debian 12 (kernel 6.6.3) for i.MX processors
We want to use it in our own design based on i.MX8m plus, so we need to port uboot and kernel.
Could you please help us to find out how to get the toolchain, rootfs, uboot and kernel source code ?
kind regards and thank you

Angel

HI @AngelF!

Thank you for contacting NXP Support!

You can see all the documentation available for Debian in the links below:

Hi Chavira,

Thank you very much for your help.

My host is ubuntu 24.04, so I follow steps and now I have everything ready to generate Debian images inside a docker container.

Now we need to be able to offer our customers a toolchain so that they can cross-compile their applications in standalone mode aoutside the container. So we would like to be able to generate the toolchain in the same way as we generate it with yocto (populate_sdk command).
How can we get the toolchain using Flexbuild?

Best regards and thank you

HI @AngelF!

According with previous cases of the same topic.

After installing flex-builder and setting up compiling environment, you could find toolchain(GCC) is deployed in /usr/bin folder.

$ which aarch64-linux-gnu-gcc
/usr/bin/aarch64-linux-gnu-gcc

Glibc is deployed in /usr/aarch64-linux-gnu/lib/ folder.

If the tool chain doesn´t exist please let me know.

Best Regards!

Hi Chavira,

Yes, I can find aarch64-linux-gnu-gcc and glibc in the container, but I was trying to generate the whole toolchain instead of copying file by file.
When installing NXP yocto firmware, we can use the populate_sdk command to generate the full toolchain and we can deploy to customers in a "professional" way.
So, with Debian 12, is it possible to generate a complete toolchain or do we have to go file by file?
Best regards and thank you

Hi @AngelF!

Talking with the internal team I got the next answer:

To cross-compile applications in standalone mode, users can use aarch64-linux-gnu-gcc compiler, which is installed by command "sudo apt-get install -y crossbuild-essential-arm64 gcc-aarch64-linux-gnu g++-aarch64-linux-gnu binutils-aarch64-linux-gnu" on Ubuntu host.

Best Regards!

Hi Chavira,

Thank you very much for your help.
This could be an option, but we are also considering building the toolchain from NXP release 6.1.22_2.0.0, as this release includes gcc 12.2.
Both Debian 12 and gcc 12.2 include glibc 2.36, and this is an important point when our customers need to cross-compile their FW.

Best regards
