Here is the .wks file I have used: part /mnt/boot --source bootimg-partition --ondisk mmcblk0 --label edgeos-boot --active --align 4096 --fixed-size=100M --fstype=msdos --use-uuid part / --source rootfs --rootfs-dir=sdcard-image --ondisk mmcblk0 --use-uuid --uuid=EA2EEE0B-5C82-4817-8439-1202B5E5651A --fstype=ext3 --label edgeos-root --align 4096 --fixed-size 1G part /mnt/rootfs2 --ondisk mmcblk0 --use-uuid --uuid=EA2EEE0B-5C82-4817-8439-1202B5E5651B --fstype=ext3 --label rootfs2 --align 4096 --fixed-size 1G part /mnt/conf --ondisk mmcblk0 --use-uuid --fstype=ext3 --label edgeos-conf --align 4096 --fixed-size 20M part /mnt/data --ondisk mmcblk0 --use-uuid --fstype=ext3 --label edgeos-data --align 4096 --fixed-size 2947M bootloader --ptable msdos ...and here is what parted thinks about the content of the image: Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 8192s 212991s 204800s primary fat16 boot 2 212992s 2310143s 2097152s primary ext3 3 2310144s 4407295s 2097152s primary ext3 4 4415487s 10500095s 6084609s extended lba 5 4415488s 4456447s 40960s logical ext3 6 4464640s 10500095s 6035456s logical ext3 When I try and resize the extended partition to the end of the disk (it's a 16GB SDCARD) with the following command I get an error parted /dev/... resizepart 4 -1s bash[177]: Expand extended partition(4)... Error: Unable to satisfy all constraints on the partition. I have searched the internet but can't seem to find any suggestions about what could be wrong, any ideas? Best Regards Peter Smith
