Why is the SD card failed to boot using make_sdimage.py to create rootfs to 7G and overall usage to 8G for A10 SoC?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to the boot rom does not deal with offsets (in bytes) bigger than 32 bits (2^32), A10 SoC would fail to boot using the image generated by the command make_sdimage.py  \
      -f \
      -P uboot_w_dtb-mkpimage.bin,num=3,format=raw,size=10M,type=A2  \
      -P rootfs/*,num=2,format=ext3,size=7G  \
      -P zImage,ghrd_10as066n2.core.rbf,ghrd_10as066n2.periph.rbf,socfpga_arria10_socdk_sdmmc.dtb,num=1,format=vfat,size=500M  \
      -s 8G  \
      -n sdimage.img

    Resolution

    Hand-crafted an SD card image manually with the partition laid out as follows:
    demo@demo-pc:~$ sudo fdisk -l /dev/sdb

     Device Boot      Start           End              Blocks            Id              System
    /dev/sdb1          22528          1046527         512000             b               W95 FAT32
    /dev/sdb2         1046528         15726591       7340032             83              Linux
    /dev/sdb3           2048          22527           10240              a2              Unknown

    The boot partition is at the low offset, and the Linux root file system partition is at the highest offset. 

    Then, manually write files into the corresponding SD card partition on a Linux host PC.
