I was trying to resize partitions of Intel Edison which runs on Yocto system. I destroyed partition 1 somehow. So when I reboot system it loops forever to boot the system correctly. So, interrupted boot sequence and checked for partitions to see what is wrong. As you can see down below partitions start from number two not one! According to error from bootloader it searches for part 1 but cannot find . So how can I add/ create/ repair manually partition 1 to recover system?
boot > printenv partitions
partitions=uuid_disk=${uuid_disk};name=u-boot0,start=1MiB,size=2MiB,uuid=${uuid_uboot0};name=u-boot-env0,size=1MiB,uuid=${uuid_uboot_env0};name=u-boot1,size=2MiB,uuid=${uuid_uboot1};name=u-boot-env1,size=1MiB,uuid=${uuid_uboot_env1};name=factory,size=1MiB,uuid=${uuid_factory};name=panic,size=24MiB,uuid=${uuid_panic};name=boot,size=32MiB,uuid=${uuid_boot};name=rootfs,size=512MiB,uuid=${uuid_rootfs};name=update,size=768MiB,uuid=${uuid_update};name=home,size=-,uuid=${uuid_home};
