更新

最好找到問題點了，主要的問題是因為opencv的作者roll back了，所以需要去修改bb檔案的commit，下方有相關的BB檔的opencv_4.2.0.imx.bb路徑，進去裡面把commit改成最新的就好了

我想要編譯一個yocto的系統鏡像 但是在fetch openCV repo的時候會發生錯誤
我有找到類似的問題
下面解決問題的討論有提到可能的原因是fetch的版本太老了
所以可以藉由更新yocto tree list就可以正常
但是我不知道怎麼更新yocto tree 因為它編譯的Img和我不同
所以應該不能使用他的更新方式去更新相關路徑
不知道有沒有方法可以更改fetch的路經呢?
或是可以下載到其他同樣版本的方法呢?

編譯的起因是因為我想要改變GPIO腳位的定義
我想要使用i.MX8上面提供的ECSPI2
但是根據的我理解 應該是要去更改編譯出來的DTS(設備樹)
設定pinctrl 更改CPU的相關腳位才對
然後再更新到裝置上面
如果理解有錯誤 請不吝指教

以下是相關的錯誤訊息
