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.
Using Hardware RESET_IN
The default Kinetis MCU firmware will enter Serial Download Mode after RESET_IN (SODIMM-pin 26) has been asserted for more than 10s.
