What's the difference between auto_yocto_bsp and radar-sdk for S32R45

Hi,

I try to build the linux image for S32R45. I find there are two ways to get linux bsp:

A: https://source.codeaurora.org/external/autobsps32/auto_yocto_bsp (S32R45_LinuxBSP_33.0_User_Manual.pdf)

B:https://source.codeaurora.org/external/autoobsps32/extra/radar-sdk (S32R45_RSDK__1.0.0/Docs/RSDK_User_Manual/index.html)

What's the difference between A and B? B contain RSDK, and A not?

Hello,

The radar-sdk (B) adds an extra yocto layer on top of the basic bsp (A). This layer takes care of generating the .ko modules, libraries, and dts changes to enable the Radar SDK (RSDK).

This means that you can use drivers for internal IPs like:

SPT, BBE32, LAX, OAL, MIPI_CSI2 and the TEF82XX Radar Front end.

One thing to keep in mind is that (B) requires to download the RSDK source code offline from nxp.com, as this source code is not public in codeaurora.

Saludos,

Alejandro

Hi, Alejandro

Do it means I can only get Binary file(such as modules, libraries) from codeaurora, and package them to linux rootfs by "bitbake" command?

download the RSDK source code offline from nxp.com, waht is the URL or path to download it?

best wishes!

Most of the recipes fetch the source code as well, but in case of the Radar SDK, it only builds the .ko, libraries and installs them into the rootfs. The recipes into meta-rsdk do not fetch the source code of the RSDK.

To get the source code of the RSDK you have to sign-in into your NXP account. Go to Software Licensing and Support-> Software Accounts->Automotive SW S32R45 Radar SDK.

You should see something like this:

Hi, Alejandro

I have installed RSDK__1.0.0 into the path as same as S32DS in windows. According to me, i can build RSDK application by S32DS.

But, I see the .ko and libraries of RSDK(LAX, SPT, etc.) will be build with command “make” on <RSDK_User_Manual>. What is the environment on <RSDK_User_Manual>? win or linux?

In addition, can I use "make" to rebuild RSDK Simply in windows, or copy RSDK__1.0.0 directory to the linux(Ubuntu) , and rebuild it?

Is there a more detailed help document?

Hi please refer to the attached document.

It contains a detailed description of the steps to build the RSDK on Windows.

Please notice that the document is for a different and previous version of the RSDK, but the overall and general steps should be quite similar.

Saludos,

Alejandro
