I want to update the uboot from 2021.04 to 2024.01 on my imx8mp. My current Yocto image create 5 partition with guid partition table. I install this image with UUU-tool and the build-in script emmc_all. Everything is fine and work.
u-boot=> mmc dev 2
switch to partitions #0, OK
mmc2(part 0) is current device
u-boot=> mmc part

When I compile the uboot 2024.01 and flash the uboot over UUU-tool
uuu.exe SDPS: boot -f flash.bin
uuu.exe FB: flash mmc2boot0 flash.bin
The uboot start but my partitions are gone
u-boot=> mmc dev 2
switch to partitions #0, OK
mmc2(part 0) is current device
u-boot=> mmc part
Partition Map for MMC device 2 -- Partition Type: DOS
Part Start Sector Num Sectors UUID Type

If I flash the old uboo (2021.04) with UUU-tool again the partitions are all restored.
First I thought that the partition table is overwrite, but it can't because with the old uboot every thing is recovered
I use an imx8mp with 8GB emmc. The emmc has two hw boot partitions.
Where is my mistake? Any sugestions?
