== Terminal Setup ==
The carrier board connects the host PC using the micro-B USB connector (J3). 
Common serial communication programs such as Minicom, HyperTerminal, Tera Term, or PuTTY can be used. 
The {{#var:HARDWARE_NAME}} board uses the second port for the Arm Cortex-A cores console.

== Booting Linux Kernel ==
This section describes how to load and boot Linux kernel using UUU. 
The Linux Kernel booting requires a bootloader. 
The bootloader includes SPL, U-Boot, Arm Trusted Firmware, OP-TEE, Sentinel
Firmware and DDR PHY Firmware. 
It can be built:
* by Yocto, the result is: tmp/deploy/images/rnx-imx93-smarc/imx-boot-rnx-imx93-smarc-sd.bin-flash_singleboot
or
* by the script u-boot-imx/tools/imx_build_firmware.sh, the result is: uboot-imx/imx-mkimage/iMX9/flash.bin
See [[{{#var:HARDWARE_NAME}} U-Boot|Building U-Boot]] for more info how to build '''flash.bin'''

=== Universal update utility ===
The Universal Update Utility (UUU) runs on a Windows or Linux OS host and is used to download images to devices on an i.MX board.

==== Downloading UUU ====
Download UUU version 1.5.21 or later from https://github.com/nxp-imx/mfgtools/releases

==== Connect USB ports ====
Follow the instructions below:
* Connect a USB cable from a computer to the J9, port USB-A (Micro-AB) port on the carrier board for download link.
* Connect a USB cable from J3, port UART-DBG (Micro-AB) port to the computer for console output.
* Open a Terminal emulator program
* Set the boot mode to "Cortex-A55 Serial Downloader", see [[#Setting Boot mode]]

=== Upload and boot ===
U-BOOT must be already built in folder: uboot-imx

$ cd arch/arm64/boot
$ cp ../../../../uboot-imx/imx-mkimage/iMX9/flash.bin .
$ wget http://download.ronetix.at/boards/doc/RNX-iMX93-SMARC/tools/kernel-smarc.uuu
$ uuu kernel-smarc.uuu

* Set the boot mode to "Cortex-A55, eMMC", see [[#Setting Boot mode]]
* reset the board

=== Boot log ===
