Thanks for the pointers. I think I came across this post but maybe did not read it carefully enough. It is true that if I generate the partitions using parted by hand and leave a gap inside the extended partition before the first logical partition then the problem goes away. What I’m struggling with is how to make wic (via the .wks file) insert this space. Peter

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?
