Store the SD card image file that you obtained in section 5.3 in any directory of the development PC. Prepare a bootable SD card by entering the following command:

Please change "/sdX " depending on the appropriate environment.
Please replace "XXX.img" with the name of the SD card image file.
It is possible to prepare a bootable SD card in environments other than Linux, such as Windows, when using Win32DiskImager etc.

7.2.2.How to change the file inside the bootable SD card

Follow the steps in section 7.2.1 and prepare the SD card.
Insert the SD card into the development PC and wait until the PC recognizes it.
Check that there are three partitions in the SD card (see Figure 3).

Table 6 notes the role of each partition.

Partion Name	Use	Remarks
IMAGE	Kernel storage area	―
ROOTFS	Android File System storage area	Will be recognized by Windows
U-DATA	User data storage area (photographs etc.)	Will be recognized by Windows
N/A	Boot Loader storage area	Unmountable

Use the following commands and copy the Android file system to the / media / ROOTFS directory.

Note: Assuming that the ROOTFS partition of the SD card is mounted on / media / ROOTFS /

Copy the library downloaded in section 5.3 onto the micro SD card (see Table 7).

Table 7: Library storage directory

Library name	Storage directory
fepslge.socfpga5xs1.so	/media/ROOTFS/system/lib/hw
gralloc.default.so	/media/ROOTFS/system/lib/hw
libGLES_android.so	/media/ROOTFS/system/lib/egl

Refer to the RocketBoards.org website and copy the Kernel image to the /media/IMAGE directory.

RocketBoards.org Website

<http://www.rocketboards.org/foswiki/Documentation/AlteraSoCDevelopmentBoardYoctoGettingStarted>

To unmount the SD card, remove the micro SD card from the development PC.
