Since Trizeps VIII Mini and Myon II are software compatible, the same bootloader may be used for both modules.

Setup Cross-Build environment (View Software-Development-Kit on how to install.):
Ubuntu 18.04 is recommended for fsl-imx-wayland-glibc-x86_64-core-image-minimal-cortexa53-crypto-trizeps8mini-toolchain-5.10-hardknott.sh.zip

Build U-Boot from source Code:
| Code Block |
|---|
~/uboot/uboot-imx$ make clean
~/uboot/uboot-imx$ make trizeps8mini_defconfig
~/uboot/uboot-imx$ make all |
This will generate the SPL, U-Boot and device-tree binary.
Note that this minimal device-tree binary will only be used by U-Boot and is not intended for use by the Linux kernel!
After these binaries have been created, they must be packed together with other components to form the bootloader:
SCU-Firmware: This NXP firmware is loaded into the Cortex-M4 (SCU: System Controller Unit).
ATF-Firmware: The SCU will load the ARM trusted firmware.
SPL / U-Boot: The ATF will load the primary loader, which will initialize the LPDDR4 and load U-Boot.

To deploy software to Trizeps VIII Mini, you may use the NXP Universal Update Utility (UUU).
Steps needed:
Enter USB Serial Download Mode
Run:
Code Block ~/uboot-imx/iMX8M$ sudo uuu -b emmc flash.bin
...
The USB Serial Download Mode (manufacturing mode) is a mode by which the i.MX8M Mini processor loads its internal ROM-firmware instead of the bootloader stored in eMMC or SD-card.
It will use the USB-OTG port to enumerate as HID-device on a connected PC.
In this mode the NXP Universal Update Utility (UUU) can be used to deploy software.
