Hi,
I'm configuring new partitions on emmc. I need 5 partitions for OTA with RAUC (2xrootfs, 2xbootfs and 1 data).
I saw [here][1] I need to configure Toradex Easy Installer to use GPT instead of the old MBR if I want more than 4 partitions.
Changing from MBR to GPT works well, I have my 5 parts on eMMC.
However, I want U-Boot to be able to determine which partition is bootable with the following command:
# part list mmc 0 -bootable devplist
as far as I tried, my devplist variable stayed in "non defined" state:
# printenv devplist
## Error: "devplist" not defined
I expected to see my partition 1 (bootfs1) in that variable as I configured my json image file with the following information: (based on https://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs)
"partition_type": "BC13C2FF-59E6-4262-A352-B275FD6F7172",
"active": true,
Do you know how can i correctly place the bootable flag on GPT partition with Toradex Easy Installer?
For debug, the attached image.json result in this mmc configuration:
Colibri iMX7 # mmc part

Secondary question : How can I set the "Name" parameter of the partition with Toradex Easy Installer ?
