研究方向
從 issue 中連結的 fork 核心原始碼和 device-tree 檔案開始，接著將其串接後的 DTB 輸出與官方 boot.img 以及預先建置的 DTB/DTBO 進行比較。檢查封裝差異以及開機期間的 ramoops 輸出。完成的標準是找出原因，並產生一個能夠封裝進 boot.img 且可成功啟動 Picasso 的 DTB/DTBO。
由索引模型根據 Issue 內容生成。
描述
I don't know if it's my mess-up, but I was not able to build the exact same dtb image as found in the official boot.img. My built dtb image is 4.4M when concatenated while the official one is only ~800K, and most importantly, when packaged into boot.img, the one built by me does not work and fails straight into bootloader. In console-ramoops I can't even see kernel messages during such a crash, which probably means the kernel isn't even booted enough to output anything to ramoops. I tried to unpack the concatenated dtb images and compare them one-by-one, but it seemed to me that even the same dtb in the two images do not really match up and differs quite significantly.
In my current effort to port LineageOS 17.1 to this device, I resorted to using OSS kernel + prebuilt DTB / DTBO for now. I hope that this can be sorted out soon as some of my kernel changes had to be dirty hacks without functional OSS DTB / DTBO.
Of course, since I'm not aware of anyone else that is currently trying to build kernel + dt for this device, it could be totally my fault instead of Xiaomi's. But for now since I do not know, I'm keeping this open until someone fixed it or could help figure out why mine does not work. My forked kernel source code (with dt included) is at https://github.com/PeterCxy/android_kernel_xiaomi_sm7250
