拿到了Hi3559A的開發板，先簡單記一下開發流程:建編譯環境，測試demo，相機功能模塊規劃，原理設計，layout,打樣貼樣，
調樣，寫驅動、應用。
萬事開頭難！
看了一下板子，幾乎和網上的一樣，感覺大家都直接就cp原廠就開賣了。

因爲板子只有一塊，裏面原來燒錄的不敢覆蓋先，調試發現板子只燒錄了linux，沒燒驅動ko，沒燒sample.通過NFS，用SDK020自帶的ko,./load3559av100_multicore -i,卻無法加載成功。
mnt/hi3559a/out/linux/multi-core/ko # ./load3559av100_multicore -i

把文件系統（yaffs2）重燒，問題還是一樣。ko是Hisi發佈的，不知道是不是燒錄的內核映像版本不同？還是SDK的toolchain版本不同？

基本確定是toolchain版本：
板子的gcc version
Linux version 4.9.37 (pub@BVT-SDK) (gcc version 6.2.1 20161016 (Huaweiliteos_v100_20170512) ) #1 SMP Mon Apr 2 19:57:38 CST 2018
020的gcc :

hdmi可以出圖，
顏色的偏的問題確定是IRCUT沒有切對，
可以用himm工具測試，
>>>
接下來，再看看SD卡的功能
