I am trying to build a embedded Linux system for
karo imx6 8033 som with 4GB SD card on it by using
buildroot to build rootfs, Configuring kernel 4.11. I am using
mfg tool to write the system on module. After flashing the SD card, I see that rootfs partition is just 300MB.
# df -h Filesystem Size Used Available Use% Mounted on /dev/root 282.5M 136.7M 130.8M 51% / devtmpfs 342.1M 0 342.1M 0% /dev
TX6DL U-Boot > mmc part Partition Map for MMC device 0 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 2048 30720 0cc66cc0-01 0c 2 32768 614400 0cc66cc0-02 83 3 647168 7086080 0cc66cc0-03 83
Each block is 512B so 614400*512=300MB. It is not enough for my work.
I want to learn in which step this configuration of partition is set while configuring rootfs, kernel or u-boot? MFG tool also has configuration file. If this partition is set while sending rootfs, kernel and U-boot, which parameter of MFG tool should I change to enhance the rootfs partition?
there is a way at this link after flashing the SD card. But I need a solution before flashing it.
