 +Gpt img file may cause errors when using parted (main and backup gpt corrupt) or gpt errors in uboot on reboot. This can be also caused by backup-gpt not overridden by image (end of disk).
 +
 +Parted:
 +
 +  Error: Both the primary and backup GPT tables are corrupt.  Try making a fresh table, and using Parted's rescue feature to recover partitions.
 +
 +Uboot (sw reboot):
 +<code>*** ERROR: Can't read GPT Entries ***
 +find_valid_gpt: *** ERROR: Invalid GPT ***</code>
 +
 +This can be fixed with sgdisk by exporting and re-importing the gpt
 +
 +  sudo sgdisk --backup=bpi-r3_sgdisk.gpt /dev/sdb
 +  sudo sgdisk --load-backup=bpi-r3_sgdisk.gpt /dev/sdb

 +
 +=== Emmc partition creation ===
 +
 +Todo...currently only via linux initrd from nor/usb
 +
 +It is possible to create gpt in uboot. Example for rk3568:
 +
 +https://source.denx.de/u-boot/u-boot/-/blob/master/include/configs/rk3568_common.h#L29
 +
 +https://elixir.bootlin.com/u-boot/latest/source/include/configs/rockchip-common.h#L85
 +
 +This creates a env var with the partition definition for rk3568 (not bpi-r3):
 +
 +<code>
 +"uuid_disk=${uuid_gpt_disk};" \
 +"name=loader1,start=32K,size=4000K,uuid=${uuid_gpt_loader1};" \
 +"name=loader2,start=8MB,size=4MB,uuid=${uuid_gpt_loader2};" \
 +"name=trust,size=4M,uuid=${uuid_gpt_atf};" \
 +"name=boot,size=112M,bootable,uuid=${uuid_gpt_boot};" \
 +"name=rootfs,size=-,uuid="ROOT_UUID
 +</code>
 +
 +Which can be used like this:
 +
 +  mmc dev 0
 +  gpt write mmc 0 $partitions
 +
 +defined table this way (blocks only):
 +
 +<code>
 +setenv partitions "uuid_disk=${uuid_gpt_disk};name=gpt,start=0,size=34,uuid=${uuid_gpt_table};name=u-boot-env,start=8192,size=1024,uuid=${uuid_gpt_env};name=factory,start=9216,size=4096,uuid=${uuid_gpt_factory};name=fip,start=13312,size=4096,uuid=${uuid_gpt_fip};name=kernel,size=100M,uuid=${uuid_gpt_kernel};name=rootfs,size=0,uuid=${uuid_gpt_rootfs}"
 +</code>
 +
 +but i got error on write...maybe because a gpt already exists
 +
 +<code>
 +MT7986> printenv partitions
 +partitions=uuid_disk=;name=gpt,start=0,size=34,uuid=;name=u-boot-env,start=8192,size=1024,uuid=;name=factory,start=9216,size=4096,uuid=;name=fip,start=13312,size=4096,uuid=;name=kernel,size=100M,uuid=;name=rootfs,size=0,uuid=
