[imx6q][android]學習筆記-修改android程式碼裡的分割槽資訊

出現這個錯誤：fs_mgr: Error opening block device (No such file or directory)fs_mgr: Failed to get ext4 fs size on /dev/block/mmcblk3p5.fs_mgr: Could not set up verified partition, skipping!

應該是imx6q-sabresd板子預設的sd槽是sd3，而我的是sd1, 所以需要將myandroid/device/fsl/imx6/sabresd_6dq.mk檔案中

PRODUCT_SYSTEM_VERITY_PARTITION := /dev/block/mmcblk3p5

改為，

PRODUCT_SYSTEM_VERITY_PARTITION := /dev/block/mmcblk0p5

還有這個myandroid/device/fsl/sabresd_6dq/fstab.freescale檔案中
