• Create a vFAT filesystem on partition 1 via sudo mkfs -t vfat /dev/sdXXX1, whereby XXX symbols the above detected SD card identifier.
• Create a an ext3 filesystem on partition 2 via sudo mkfs.ext3 /dev/sdXXX1, whereby XXX symbols the above detected SD card identifier.
• No extra filesystem for partition 3 is needed.

...

• Copy the linux root filesystem to the ext3 partition 2 and decompress it if it is compressed.
  
  • For Linux this can be done using the following steps:
    • Mount the ext3-partition (in this case 2) to an available folder (e.g. /mnt/mountpoint) via sudo mount /dev/<correct partition of the SD card> /mnt/mountpoint
    • Extract the <root filesystem>.tar.gz via sudo tar -xvf <path to compressed root filesystem>.tar.gz -C /mnt/mountpoint/ 
    • Synchronise the buffers via sudo sync

0xA2 Partition 3:

• Insert the SD card to a Windows OS.
• Start the SoC EDS Shell as administrator. To do that navigate to C:...\intelFPGA\18.1\embedded\ , right click on the file "Embedded_Command_Shell.bat", and select "Run as administrator". Click Yes in the window "User Account Control".
• Identify one of the SD card letter(s).
• Copy the preloader to the 0xA2 partition 3 via alt-boot-disk-util -p <path to the preloader image>preloader-mkpimage.bin -a write -d <SD card letter>

mount/umount muss noch beachtet werden!!!!!

Requirements

Was soll das folgende heißen?

Unknown - partition for u-boot config script and how to setup (uboot.scr)

                   The main u-boot environment can be saved with saveenv

vfat-partition:          optional - Linux-Config-Script / main u-boot instead a2-partition

Data of each partition

Before writing data to the partitions, unmount the device
      sudo umount /dev/sdX*
and plage the SD card  in and out of the card reader.

W95 Fat32 partition

The W95 Fat32 partition needs to be formated.
   sudo umount /dev/sdX*
   sudo mkfs -t vfat /dev/sdXp (p=partition number, needs to be 1)

...

u-boot.img muss auf diese Partition!!!!

ext(2/3/4) partition

The ext(2/3/4) partition is formated via:
   sudo mkfs.ext3 /dev/sdXp   (p=partition number, should be 2)

After the operation finishes, use a data browser to copy the Linux root file system / rootfs   to it.
An other approach is needed for a compressed root file system. Befor decompressing a ... .tar.gz file to the SD card, it needs to be mounted to a mounting point. This requires an existing folder to write to. Usually these folder is placed inside the mnt folder, for example:   sudo mkdir /mnt/card   (create mounting point folder)

Mount it:
   sudo mount /dev/sdXp /mnt/card   (p=partition number, should be 2)

//////////////////////// SOC EDA Installation für Linux !!!!!!!!!!!!!!

a2 partition

This partition needs no formatting, the data needs to be copied with the tool
alt-boot-disk-util .

The tool should be in the folder:
   \intelFPGA\18.1\embedded\host_tools\altera\diskutils
Copy the   SPL u-boot.bin   and   the Main u-boot.img   to it, change to the directory:
   cd pathToAlt-boot-disk-util   (cd=change directory)
and run:
   sudo pathToAlt-boot-disk-util -p preloaderImage.bin -b mainU-boot.img -a write /dev/sdX   (the tool finds the a2 partition)

Lastly, unmount the Sd card ( sudo umount /dev/sdX* ) and test it.

(The tool dd can also be used to write the preloader - sudo dd if=pathToSplUboot of=/dev/sdXp seek=0 bs=64k conv=fsync)
