Supplement for Building Older AUTO Linux BSPs

はい

1. Introduction

Since the CodeAurora shutdown, in order to facilitate the build for older BSPs(versions prior to 34.0), the method with necessary patches/scripts is provided by NXP to adapt the changes, for details, it could be accessed via the following link:

https://community.nxp.com/t5/S32G-Knowledge-Base/How-to-build-older-Auto-Linux-BSPs/ta-p/1637516

(Note that the operation steps provided by this document could be used solely without referencing the document from previous link.

This document could be treated as a supplement of the above link, since the operations would only workable upon the scripts provided from the original document, for diving into the internals, it is strongly suggested reading the document above)

However, recently the following errors may be found during the old BSP builds:

./migrate.sh --full --work_path ./BSP34 --release_branch release/bsp34.0

By investigating the issue, it is caused by the service changes from Linaro.

2. Additional Operations

For fixing the issue met, the following new steps are suggested for the users who still want to utilize the older BSPs, taking BSP34.0 builds as an example below:

Prepare the working scripts/patches mentioned in the previous link mentioned:

git clone https://github.com/nxp-auto-linux/linux-bsp-utils.git
cd linux-bsp-utils/codeaurora_migration/

Manually creating working directory and enter it, to start the repo init operation.

mkdir BSP34/auto-bsp
cd BSP34/auto-bsp
repo init -u https://github.com/nxp-auto-linux/auto_yocto_bsp -b release/bsp34.0

Then apply the patch in BSP34/auto-bsp/.repo/manifests directory
```
cd BSP34/auto-bsp/.repo/manifests
patch -p1 < OldBSPs.patch
```
Execute the script that downloaded from github in step 1
```
cd ../../../..
./migrate.sh -s -p ./BSP34
```

Enter the bitbake shell

cd BSP34/auto-bsp
source nxp-setup-alb.sh -m <target_machine>

Start a build and then test the image built on the board
```
bitbake <target-image>
```
