Hi everybody:
I'm building wic and ubifs images for a custom MACHINE, this is my machine conf file:
#@TYPE: Machine

I've also created an `u-boot-engicam.bbappend` recipe to patch also the u-boot default config:

Just to set my custom DT from default. Also This one is my custom DT:
https://jfernandz.me/~wyre/imx6ull-microgea-joifi.dts.txt
But you can compare it with the one this vendor ships by default for their evaluation carrier board:
https://jfernandz.me/~wyre/imx6ull-microgea-microdev.dts.txt
As you can see in the MACHINE config file I'm deploying both dtb. The problem is the SoM is able to boot the .wic image from mmc. However, when I flash the NAND with the script I'm using:
setenv mtdids 'nand0=gpmi-nand'
setenv mtdparts 'mtdparts=gpmi-nand:4m(boot),8m(kernel),1m(dtb),-(rootfs)'
#zImage
tftp ${loadaddr} zImage
nand erase 0x00400000 0x00800000
nand write ${loadaddr} 0x00400000 0x00800000
#DTB:
tftp ${loadaddr} imx6ull-microgea-joifi.dtb
nand erase 0x00c00000 0x00100000
nand write ${loadaddr} 0x00c00000 0x00100000
#FS:
nand erase.part rootfs
tftp ${loadaddr} rootfs.ubifs
ubi part rootfs
ubi create rootfs
ubi write ${loadaddr} rootfs ${filesize}
ubifsmount ubi0:rootfs
ubifsls
It's apparently properly flashed as you can see:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) ]---
So the kernel isn't apparently able to locate/mount properly the rootfs partition. The vendor factory new DT produces the same output, So I'd say it's not a DT thing. Also ... as I've said ... the SoM is perfectly able to boot from mmc if I flash there the .wic image variant (produced in the very same execution of bitbake)
I think I must be missing something, so ... I'd appreciate your help and any clue on why is happening this.
Thank you very much.

Do you think it might be due this?

Well, I think I found the problem, actually the U-Boot version (maybe this specific build)
U-Boot 2016.07-gfab75f3-dirty (May 16 2019 - 12:08:22 +0200)
That one is the brand new U-Boot build it comes flashed in NAND from the provider. The U-Boot version this recipe delivers (u-boot.imx) boots perfectly the som from NAND. However ... I'd like to understand why this was happening, apparently the roofs.ubifs wasn't being flashed in the proper gpmi partition?
ubi0: attached mtd1 (name "mtd=3", size 499 MiB)
The new u-boot build (I mean the mine one) apparently uses mtd4 ... but I'm not sure if this is because of some environment misconfig or because of the build itself.
Also ... this is a problem for me... because this will mean I will have to look for a method to flash u-boot from itself because I find unconvenient to have to boot a mmc (SDCard) to flash u-boot and then boot the new flashed u-boot to flash the whole NAND and being able to boot the som.
