依照著clone device/brobwind/rpi3，增加local_manifest, repo sync..
repo init -u https://android.googlesource.com/platform/manifest -b android-9.0.0_r50 repo sync
出現 mkfs.fat Error , 據說是 4.1 版的問題，所以..

手動把 sd card partition1 mount 起來，把 out/.../rpiboot/ 下的檔案都 copy 過去，就可以開機了。所以猜是 fat16copy.py 的修改失敗了。
看看mkfs.fat 的 option 有沒有有關 reserved_sector ...
mkfs.fat 4.1 (2017-01-24)
No device specified.
Usage: mkfs.fat [-a][-A][-c][-C][-v][-I][-l bad-block-file][-b backup-boot-sector]

[-h hidden-sectors][-F fat-size][-r root-dir-entries][-R reserved-sectors]
[-M FAT-media-byte][-D drive_number]
[--invariant]
[--help]
/dev/name [blocks]
也順便看一下 build/make/tools/fat16copy.py，其中 main:
print("Usage: fat16copy.py [ ...]")
print("Files are copied into the root of the image.")
print("Directories are copied recursively")
看來就是一個很方便直接 copy file 到image file 的 tool，不用 loop mount ..======== 參考reserved sector = 1
所以就是..
