Unexpected U-Boot behavior when building Boot2Qt distro with Yocto

I am working with NXP i.MX 8QuadXPlus Multisensory Enablement Kit (MEK) and I'd like to use Boot2Qt so I created Boot2Qt distro using this guide, the steps I did are:
$ git clone -b thud git://code.qt.io/yocto/meta-boot2qt.git $ cd meta-boot2qt $ ./b2qt-init-build-env init --device imx8qxpmek $ export MACHINE=imx8qxpmek $ source ./setup-environment.sh $ bitbake -k b2qt-automotive-qt5-image.bb
After a while the image is generated, then I use the NXP manufacturing tool to flash it to the eMMC that MEK board includes:
sudo ./uuu -v -b emmc_all imx-boot-imx8qxpmek-sd.bin b2qt-automotive-qt5-image-imx8qxpmek.img
Finally Boot2Qt boots fine and I can see Neptune starting, but when I try to modify the U-Boot enviroment variables, somehow the boot partition gets corrupted.
Here is my U-Boot outputU-Boot 2018.03-imx_v2018.03_4.14.98_2.0.0_ga+g0d6d880779 (Jan 29 2020 - 17:15:28 +0000) CPU: Freescale i.MX8QXP revB A35 at 1200 MHz at 22C Model: Freescale i.MX8QXP MEK Board: iMX8QXP MEK Boot: MMC0 DRAM: 2.8 GiB VService: Connection is ok on MU mu@5d230000 TCPC: Vendor ID [0x1fc9], Product ID [0x5110], Addr [I2C1 0x50] MMC: FSL_SDHC: 0, FSL_SDHC: 1 Loading Environment from MMC...

Any tip of what I need to do to get to the modify the environment variables in U-Boot without corrupting my boot partition? or maybe I need to modify something in my recipes?
Thanks
