I forgot to attach some additional details:
```
sudo fdisk -l /dev/sda
Disk /dev/sda: 58.24 GiB, 62534975488 bytes, 122138624 sectors
Disk model: STORAGE DEVICE
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Device Boot Start End Sectors Size Id Type

```
The image was generated via buildroot using genimage:
```
image boot.vfat {
vfat {
file EFI/BOOT/BOOTAA64.EFI {
image = "Image"
}
extraargs = "-F32" # tried with and without this flag,
same issue.
}
size = 255M
}
image sdcard.img {
hdimage {
}
partition bootloader {
in-partition-table = false
offset = 512
image = "u-boot.bin"
}
partition rootfs {
partition-type = 0xEF
bootable = "true"
image = "boot.vfat"
offset = 1M
}
}
```
bootflow -la without the debug messages:
```
=> bootflow scan -la
