= Introduction =
This article describes flashing U-Boot firmware image with a Linux Host using Universal Update Utility (hereinafter '''UUU''').

{{Note|Follow the [https://github.com/NXPmicro/mfgtools/blob/master/README.md Universal Update Utility instructions] to install and setup the UUU tool on a host Linux station.}}

= Getting Recovery U-Boot Firmware Image =
* Download the '''IOT-GATE-IMX8PV2 firmware recovery image''' from the [https://www.compulab.com/products/iot-gateways/iot-gate-imx8pv2-industrial-iot-edge-gateway/#devres U-boot section of IOT-GATE-IMX8PV2 Resources] to the host Linux station.
* Extract the archive on the host Linux station:
<pre>
unzip iot-gate-imx8pv2_firmware-recovery-image_YYYY-MM-DD.zip -d /path/to/iot-gate-imx8pv2-firmware
</pre>

= Determining RAM size =
Determine the correct DRAM size of the IOT-GATE-IMX8PV2 according to the label located on the bottom side of the device. DRAM size is encoded in the unit's '''D''' [https://www.compulab.com/products/iot-gateways/iot-gate-imx8pv2-industrial-iot-gateway/#specs option]. 
Use the table below to determine '''DRAM_CONF''' value:

{| border="1" cellspacing="1" cellpadding="3" style="border-collapse:collapse; text-align:center;"
! Product '''D''' Option
! DRAM Size (MB)
! DRAM_CONF
|-
| D1
| 1024
| d1d8
|-
| D2
| 2048
| d2d4
|-
| D4
| 4096
| d2d4
|-
| D8
| 8192
| d1d8
|}

DRAM configuration is handled by the bootloader (SPL/U-Boot), and the relevant information is passed to the Linux kernel via the Device Tree. 
In particular, the detected DRAM size, expressed in megabytes (MB), can be read from the file ''/proc/device-tree/som.info/dram.size''. 
The following commands can be used to determine the DRAM size on a running IOT-GATE-IMX8PV2 gateway:

* DRAM size in megabytes (MB):
<pre>compulab@iot-gate-imx8pv2:~$ echo $(</proc/device-tree/som.info/dram.size)</pre>
* DRAM size in gigabytes (GB):
<pre>compulab@iot-gate-imx8pv2:~$ echo $(( $(</proc/device-tree/som.info/dram.size) / 1024 ))</pre>

= Flashing U-Boot Firmware =
* Power off the IOT-GATE-IMX8PV2 device.
* Remove the [[IOT-GATE-IMX8PV2:_Getting_Started#Service_bay_layout|Service bay door]] to access the USB programming port.
* Connect the IOT-GATE-IMX8PV2 micro-USB connector with the workstation USB port using a standard micro-USB cable.
* Power on the IOT-GATE-IMX8PV2 device via the main DC input.
* Issue the following commands on the host Linux station:
<pre>
uuu -lsusb
</pre>

# Make sure the CP2104 driver is available with your operating system, otherwise install CP2104 driver onto the host PC from https://www.silabs.com/documents/public/software/CP210x_Windows_Drivers_with_Serial_Enumeration.zip
# Identify the host PC interface and port number that will be used for communication with the device:
#* In most Linux PCs, the serial port will be denoted as one of the following (where n is a positive integer): /dev/ttyUSB0, /dev/ttyUSB1 ... /dev/ttyUSBn
#* In Windows PCs, the serial port usually will be denoted as one of the following (where n is a positive integer): COM1, COM2 ... COMn
# Start a terminal emulation program (such as [https://www.putty.org/ PuTTY] on Windows or minicom on Linux).
# In the port configuration section of the terminal emulation program select the port identified in previous step and set the following serial port parameters:
<blockquote>
{{:SB-SOM: serial port parameters table}}
</blockquote>

= Connection and Login =
This Debian rootfs comes with a default sudo user ''compulab''.
User password has to be set at the very first login:
<pre>
Debian GNU/Linux 13 iot-gate-imx8pv2 ttymxc1

Default User: compulab

iot-gate-imx8pv2 login: compulab
You are required to change your password immediately (administrator enforced).
New password:
Retype new password:
</pre>

To login into the Linux system, use a terminal emulator as described [[IOT-GATE-IMX8PV2: Getting Started#Quick_Setup|here]], or connect through the network (ssh).

= Industrial I/O Interfaces =
The IOT-GATE-IMX8PV2 features two configurable Industrial I/O ports. Each port can be individually configured to operate in either RS485 or CAN mode. 
In addition, the IOT-GATE-IMX8PV2 provides four programmable signals that can be used as either digital inputs or digital outputs. 
These three interfaces are treated as a virtual I/O stack, where the RS485/CAN ports are managed as virtual slots '''A''' and '''B''', and the Digital I/O interface is managed as virtual slot '''C'''. 

== I/O Initialization Script ==
During O/S boot, the IOT-GATE-IMX8PV2 automatically runs the Industrial I/O initialization script. The script examines the user-defined I/O configuration, such as RS485, CAN, and Digital I/Os, and creates access files for all enabled interfaces. 

Industrial I/O Stack access directory example:

<pre>
/run/iot-gate-imx8pv2/io_stack/
└── frontplane
├── A
│ ├── access
│ │ └── can -> /sys/class/net/canA
│ └── type.CAN
├── B
│ ├── access
│ │ └── tty -> /dev/ttymxc0
│ └── type.RS485
└── C
├── access
│ ├── di.map
│ └── do.map
└── type.DIO
</pre>

== CAN bus ==
The IOT-GATE-IMX8PV2 CAN 2.0B interfaces are implemented with i.MX8M Plus CAN controllers (aka FlexCAN). 
FlexCAN interface key characteristics:
* Supports CAN 2.0B protocol specification
* Galvanic isolation from the main unit
* Optional 120Ω termination resistors

The CAN signals are routed to the Industrial I/O connector as follows:

|-
|}

{{Important|External voltage supply in the range 6-24V DC must be supplied via DIO_VIN pin for correct operation of digital inputs and outputs}}
Please refer to [https://www.compulab.com/products/iot-gateways/iot-gate-imx8pv2-industrial-iot-edge-gateway/#devres IOT-GATE-IMX8PV2 reference guide] for Industrial I/O Connector full pin-out. 

=== Enable Digital Inputs and Outputs ===
The IOT-GATE-IMX8PV2 provides four programmable signals that can be configured as either digital inputs or digital outputs. 
The Digital I/O interface is managed as virtual slot '''C'''. 
To configure the direction of a specific signal, use the [[IOT-GATE-IMX8PV2:_Debian_Linux:_iotg-config_Configuration_Tool|''iotg-config'']] tool (Industrial I/O Stack Options → [[IOT-GATE-IMX8PV2:_Debian_Linux:_iotg-config_Configuration_Tool#Configure_Industrial_I.2FO_Slots|Configure Industrial I/O Stack]] → Slot C.

=== Access DIO Interface ===
During O/S boot, the [[IOT-GATE-IMX8PV2:_Debian_Linux:_How-To_Guide#I.2FO_Initialization_Script|Industrial I/O initialization script]] automatically creates access files for the DIO signals according to trhe user-defined configuration. 
DIO signals can be accessed either through the DIO utilities developed by Compulab and included in the IOT-GATE-IMX8PV2 Debian Linux image, or through the GPIO utilities provided by the '''gpiod''' package. 

In the following example, digital signals 0 and 3 are configured as inputs (DI0 and DI3), while signals 1 and 2 are configured as outputs (DO1 and DO2).

==== Show DIO to GPIO chip/line mapping ====
Use '''dioinfo''' to show Digital Input and Output GPIO chip/line mapping. 
<pre>
compulab@iot-gate-imx8pv2:~$ /opt/cl-iotg/shell/dioinfo
Stack Slot C: DIO (4x DI; 4x DO)
~~~~~~~~~~~~~~~~~
Digital GPIO GPIO
Signal Chip Line
~~~~~~~~~~~~~~~~~
DI 0: 2 19
DI 1: -1 -1
DI 2: -1 -1
DI 3: 1 10
~~~~~~~~~~~~~~~~~
DO 0: -1 -1
DO 1: 5 5
DO 2: 5 6
DO 3: -1 -1
~~~~~~~~~~~~~~~~~
</pre>
Note that the table above contains valid GPIO chip/line information only for the DI0, DO1, DO2, and DI3 signals. 
The remaining entries are not valid because the corresponding signals are not accessible.

==== Reading Digital Inputs ====
'''Example''' 
Read state of input pin '''DI0''':
* Use '''dioget''' to access digital inputs. 
<pre>
compulab@iot-gate-imx8pv2:~$ dioget=/opt/cl-iotg/shell/dioget
compulab@iot-gate-imx8pv2:~$ sudo ${dioget} 0
</pre>
* Alternatively, use '''gpioget''' to access the underlying GPIO:
<pre>
compulab@iot-gate-imx8pv2:~$ sudo gpioget --numeric -c 2 19
</pre>

==== Setting Digital Outputs ====
'''Example''' 
Setting output pin '''DO2''' to HIGH state:
* Use '''dioset''' to access digital outputs. 
<pre>
compulab@iot-gate-imx8pv2:~$ dioset=/opt/cl-iotg/shell/dioset
compulab@iot-gate-imx8pv2:~$ sudo ${dioset} 2 1
</pre>
* Alternatively, use '''gpioset''' to access the underlying GPIO:
<pre>
compulab@iot-gate-imx8pv2:~$ sudo gpioset --toggle 0 -c 5 6=1
</pre>

= RTC =
IOT-GATE-IMX8PV2 RTC is implemented with the AM1805 real-time clock (RTC) chip.
Back-up battery keeps the RTC running to maintain clock and time information whenever the main power supply is not present.

== Accessing and setting the RTC ==
* To access the RTC time and date run:
<pre>
compulab@iot-gate-imx8pv2:~$ sudo hwclock
2026-10-26 09:09:12.642662+00:00
</pre>

* To set the date and write it into the RTC do the following:
<pre>
compulab@iot-gate-imx8pv2:~$ sudo date -s "31 Dec 2021 10:00:00"
Fri Dec 31 10:00:00 IST 2021
compulab@iot-gate-imx8pv2:~$ sudo hwclock -w
compulab@iot-gate-imx8pv2:~$ sudo hwclock
2021-12-31 10:00:08.323645+02:00
</pre>

= Watchdog =
IOT-GATE-IMX8PV2 watchdog function is implemented with the i.MX8M Plus watchdog.
By default watchdog is not configured.
:<pre>compulab@iot-gate-imx8pv2:~$ systemctl show | grep RuntimeWatchdog</pre>
:<pre>RuntimeWatchdogUSec=0</pre>
The value '''RuntimeWatchdogUSec=0''' means watchdog logic is disabled: no watchdog device is opened, configured, or pinged

== Watchdog configuration ==
* Edit ''/etc/systemd/system.conf'' file to configure watchdog related parameters, in particular '''RuntimeWatchdogSec''' and '''ShutdownWatchdogSec'''.
:'''RuntimeWatchdogSec''' - specifies the watchdog timeout for runtime services, meaning services that are actively running during normal system operation. The value is in seconds and should be set to a positive integer. 
:'''ShutdownWatchdogSec''' - specifies the watchdog timeout for the shutdown process, insuring the system doesn't hang indefinitely during the shutdown. The value is in seconds and should be set to a positive integer. 

* Reboot the device
* Verify watchdog configuration
:<pre>compulab@iot-gate-imx8pv2:~$ systemctl show | grep RuntimeWatchdog</pre>
:<pre>RuntimeWatchdogUSec=10s</pre>

== Watchdog testing ==
* Run the following command to simulate kernel panic:
:<pre>root@iot-gate-imx8pv2:/home/compulab# echo "c" | sudo tee /proc/sysrq-trigger</pre>
* As a result, the watchdog is not fed and the system reboots after 10 sec.

== System setup ==
MCM-iMX8PV2 evaluation kit is preloaded with MCM-iMX8PV2 Yocto Linux image.
# Make sure jumper '''E3''' is removed (default state).
# Make sure that the main power switch '''SW1''' is in the '''OFF''' position.
# For kits ordered with LCD panel: use the '''EB-HDRLVDS''' adapter to connect the LCD panel (if ordered with the kit) to connectors '''P13''' and '''P14'''.
# Connect a standard USB cable (included in the kit) between your host PC and the evaluation kit micro-USB2.0 connector '''P3'''.
# On your computer, start a terminal emulation program (such as HyperTerminal) with the following serial port settings:
<blockquote>
{{:SB-SOM: serial port parameters table}}
</blockquote>

== Starting the system ==
# Connect the DC 12V power supply adapter (included in the kit) to main DC power connector '''J1'''.
# Toggle the main power switch '''SW1''' to '''ON''' position.
# Follow the messages in your terminal emulator program until you see the linux shell command line prompt.
# Use the superuser credentials to log in:
:: user: root 
:: pass: no password
{{note|In case of no messages appear in your terminal emulation program, please refer to the detailed [[SB-UCM-iMX8: HOWTO: USB Console|USB console]] guide.}}
