This section provides information about the BOE LVDS LCD Display with Capacitive Touch Panel (CTP) Set. The iMX93 Industrial Development Kit in this configuration is equipped with Yocto 5.0 (Scarthgap) (Linux version 6.6.52) to support LVDS display with a touchscreen layer. The display set comes with convenient acrylic stand.

==Required Components==
The iMX93 Industrial Kit Display Set is compact and ready-to-use solution. The following mechanical and electrical accessories are included in the Display set:

* LVDS LCD Display: BOE EV121WXM-N10-1850 (DY1212W-4856 12.1" (WXGA) TFT LCD) 1024*800 RGB with Capacitive Touch Panel (CTP)
* DY1212W-4856 LVDS Cable [https://downloads.voipac.com/files/iMX93_Industrial_Development_Kit/accessories/BOE_LVDS_Capacitive_Display_Set/BOE_LVDS_Capacitive_Display-LVDS_Cable-Errata.pdf with two group wires swapped to enable touch panel]
* Voipac BOE LVDS Display Adapter
* 1x 6-core Flat Flex Cable (FFC) 10-06-D-0050-C-4-08-4-T
* 1x 40-core Flat Flex Cable (FFC) 05-40-D-0050-A-4-06-4-T

==Mechanical connection==
This part shows how to correctly connect cables and parts of the BOE Display Set. To enable smooth communication between the board and the display, connect following parts as shown below:

* DY1212W-4856 LVDS Cable to rear side of the BOE Display
* Mount BOE LVDS Display Adapter on bottom side of the baseboard
* Connect and link cables together with the adapter and baseboard

'''''NOTE:''''' Due to easier handling when connecting the cables, we recommend to connect BOE LVDS Cable to the Display Adapter on baseboard as last one.

=== Hardware jumpers BOE LVDS ===
Make sure that configurable 0R resistors are assembled to support the default Newhaven / BOE LVDS0 interface.

iMX8M Industrial Flashing Procedure

2026-08-05T08:58:38Z

Voipac: /* Flashing procedure */

[[Category:iMX8M Industrial Development Kit]]
[[Category:iMX8M Industrial Software]]

<div style="float:right">__TOC__</div>
This page describes how to flash [https://downloads.voipac.com/index.php?p=iMX8M_Industrial_Development_Kit/module/software binaries] into iMX8M Industrial Module's eMMC Flash memory or into SD card that is located on the iMX Development Baseboard. 

'''''Note: All of the steps listed below are NOT REQUIRED for standard configuration modules and development kits.'''''

== Installing Universal Upload Utility (UUU) ==
=== Linux ===
<syntaxhighlight lang="bash">
git clone https://github.com/NXPmicro/mfgtools.git
cd mfgtools
mkdir .build && cd .build && cmake .. && make -j`nproc`
</syntaxhighlight>

The binary called '''''uuu''''', which is used for flashing, is located in .build/uuu directory.

=== Windows ===
* Go to: https://github.com/NXPmicro/mfgtools/releases
* Select the latest stable release. Example: '''''Releases/uuu_1.4.243''''': https://github.com/NXPmicro/mfgtools/releases/tag/uuu_1.4.243
* Download: [https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.4.243/uuu.exe uuu.exe]
* Save the file into: C:\uuu

== Preparing the binaries ==
* Download the default bootloader file: [https://downloads.voipac.com/files/iMX8M_Industrial_Development_Kit/module/software/yocto/binaries/imx-boot imx-boot]
* Download the default WIC filesystem image: [https://downloads.voipac.com/files/iMX8M_Industrial_Development_Kit/module/software/filesystem/voipac-image-imx8mq.wic voipac-image-imx8mq.wic]

== Flashing procedure ==
* Set serial downloader mode by sliding DIP switch S1 BOOT positions to: 1-OFF, 2-ON
[[File:iMX8M_Industrial_Development_Kit-Serial_donwloader_mode.png|400px]] 

* Plug USB Micro-B cable to baseboard CONSOLE connector and PC '''''Note:''''' Make sure that UART1 and UART2 jumpers are in CP2105 positions (USB/UART bridge). 
[[image:iMX_Development_Baseboard-Serial_console_jumpers-iMX8M_COM.png|594px]] 

* Plug USB-C cable to baseboard USB-C connector and PC '''''Note:''''' Powering of the development kit is not required during the flashing procedure. '''''Note:''''' After connecting 2 development board cables, 2 serial ports named ''Silicon Labs CP210x USB to UART Bridge'' should appear in the controlling PC. 
[[image:iMX8M Industrial Development Kit-Serial-consoles-recognized.png|594px]] 
* Default Serial Port Settings
[[image:Serial_Port_Setup.png ]] 

* Download and copy imx-boot and *.wic files into ''uuu\'' directory
* Choose one of the following commands to start the flashing process:
=== eMMC Flash Memory (default) ===

==== Linux ====
<syntaxhighlight lang="bash">
sudo ./uuu -b emmc_all imx-boot voipac-image-imx8mq.wic
</syntaxhighlight>

==== Windows ====
<syntaxhighlight lang="bash">
uuu.exe -b emmc_all imx-boot voipac-image-imx8mq.wic
</syntaxhighlight>

=== SD Card ===

==== Linux ====
<syntaxhighlight lang="bash">
sudo ./uuu -b sd_all imx-boot voipac-image-imx8mq.wic
</syntaxhighlight>

==== Windows ====
<syntaxhighlight lang="bash">
uuu.exe -b sd_all imx-boot voipac-image-imx8mq.wic
</syntaxhighlight>

=== Flashing logs ===

== Running the newly flashed binaries ==
After completing the above steps, eMMC Flash memory or SD Card is flashed and the following steps are to be performed to boot the new image:

* Unplug USB-C cable from PC
* Set Boot mode by sliding DIP switch S1 BOOT positions to: 1-ON, 2-OFF
[[File:iMX8M_Industrial_Development_Kit-Boot_mode.png|400px]] 

* Make sure that S2 BOOT and S3 BOOT DIP switches are in correct positions in order to boot from the selected storage media (eMMC Flash memory or SD Card):
==== eMMC Flash Memory boot (default) ====
[[image:iMX8M_Industrial_Development_Kit-eMMC_boot_DIP_switch_configuration.png|400px]] 

==== SD Card boot ====
[[File:iMX8M_Industrial_Development_Kit-SD_boot_DIP_switch_configuration.png|400px]] 
* Connect USB Micro-B debug cable, switch on the power and the development kit starts booting with the new binaries 

== Setting DTB file ==
* To set a correct DTB file, stop autoboot.

* Use these commands to set a DTB file for the image loaded in eMMC:
<syntaxhighlight lang="bash">
u-boot=>fatls mmc 0:1
u-boot=>setenv fdt_file imx8mq-evk-voipac-hdmi.dtb
u-boot=>saveenv
</syntaxhighlight>

* Use these commands to set a DTB file for the image loaded in SD Card (example for Newhaven Display):
<syntaxhighlight lang="bash">
u-boot=>fatls mmc 1:1
u-boot=>setenv fdt_file imx8mq-evk-voipac-lvds-newhaven.dtb
u-boot=>saveenv
</syntaxhighlight>

[[File:imx8m_dtb_setting.png|740px]] 

* To boot the image, reset the board or type the boot command:

<syntaxhighlight lang="bash">
u-boot=>boot
</syntaxhighlight>
