== WiFi ==
'''''Note:''''' This WiFi section was tested with the iMX8M Industrial Module in Max and Pro configurations. For Basic configuration, wireless connectivity can be achieved via [[#PCI Express socket + Micro SIM slot|PCIe Mini]] and/or [[#M.2 key B socket + Micro SIM slot|M.2 key B]] slots located on the baseboard. For more information see [[iMX8M Industrial Development Kit|the iMX8M Industrial Module comparison]]. 

'''''Note:''''' Only the Basic configuration of iMX8M Industrial Module provides access to PCI Express signals via PCIe Mini and M.2 key B sockets soldered on the baseboard, instead of using the interface for WiFi and Bluetooth module on the COM.

'''''Note:''''' This WiFi section was tested with the iMX8M Industrial Module in Max and Pro configurations. For Basic configuration, wireless connectivity can be achieved via [[#PCI Express socket + Micro SIM slot|PCIe Mini]] and/or [[#M.2 key B socket + Micro SIM slot|M.2 key B]] slots located on the baseboard. For more information see [[iMX8M Industrial Development Kit|the iMX8M Industrial Module comparison]]. 

'''''Note:''''' Only the Basic configuration of iMX8M Industrial Module provides access to PCI Express signals via PCIe Mini and M.2 key B sockets soldered on the baseboard, instead of using the interface for WiFi and Bluetooth module on the COM.

SATA disk modules provides reliable storage. There are multiple benefits for using them:
* iMX6 TinyRex can use SATA disk to store bootloader and boot directly from. iMX6 TinyRex Modules in Pro, Max, Ultra and UltraPlus configurations support SATA interface
* sizeable capacity
* available in extended temperature range
* Mean Time Between Failures exceeding 1000000 hours
* supports wear leveling, SMART and power failure management for data integrity 
[[image:iMX6_TinyRex_with_SATA_drive.jpg|800px]] 

Although multiple disk on modules can be utilized, iMX6 Rex SATA Disk Module was handpicked as an excellent choice in terms of physical size, power consumption and reliability:

== Bootloader settings ==
The primary bootloader (loaded by ROM bootloader) will chainload the second bootloader. Chainloaded bootloader is configured to load kernel and device tree from first partition and rootfs from second partition in this case. 

'''''Notes:'''''
* Primary bootloader environment must be set to run new boot mode ('bmode sata')
* Chainloaded bootloader environment must be set to properly load and execute kernel ('setenv sataroot ...')

 '''''Boot sequence:'''''
* ROM bootloader loads and execute primary bootloader based on eFuses configuration (SPI/SD)
* Primary bootloader (SPI/SD) with set i.MX6 register to overwrite primary boot device and will reset SOC
* ROM bootloader will load and execute bootloader from newly configured boot device (SATA)

 Configuring primary (SPI/SD) bootloader. Changes are applied in uboot environment:
<syntaxhighlight lang="bash">
setenv bootcmd 'bmode sata'
saveenv
reset
</syntaxhighlight>

Configuring chainloaded (SATA) bootloader:
<syntaxhighlight lang="bash">
setenv sataroot '/dev/sda2 rootwait rw'
setenv sataargs 'setenv bootargs console=${console},${baudrate} ${extra} ${video} root=${sataroot}'
setenv sataboot 'echo Booting from sata ...; run sataargs; if sata init; then fatload sata 0:1 ${loadaddr} ${image}; fatload sata 0:1 ${fdt_addr} ${fdt_file}; bootz ${loadaddr} - ${fdt_addr}; fi'
setenv bootcmd 'run sataboot'
sata init; saveenv
boot
</syntaxhighlight>

== Performance comparison ==
The transfer speed differences between SD card and SATA module are listed in the table below . The test was performed using flexible I/O tester:
<syntaxhighlight lang="bash">
fio --loops=5 --size=100m --filename=/home/root/fiotest.tmp --stonewall --ioengine=libaio --direct=1 \

SATA disk modules provides reliable storage. There are multiple benefits for using them:
* iMX6 TinyRex can use SATA disk to store bootloader and boot directly from. iMX6 TinyRex Modules in Pro, Max, Ultra and UltraPlus configurations support SATA interface
* sizeable capacity
* available in extended temperature range
* Mean Time Between Failures exceeding 1000000 hours
* supports wear leveling, SMART and power failure management for data integrity 
[[image:Pcam-5C.png|800px]] 

Although multiple disk on modules can be utilized, iMX6 Rex SATA Disk Module was handpicked as an excellent choice in terms of physical size, power consumption and reliability:

== Bootloader settings ==
The primary bootloader (loaded by ROM bootloader) will chainload the second bootloader. Chainloaded bootloader is configured to load kernel and device tree from first partition and rootfs from second partition in this case. 

'''''Notes:'''''
* Primary bootloader environment must be set to run new boot mode ('bmode sata')
* Chainloaded bootloader environment must be set to properly load and execute kernel ('setenv sataroot ...')

 '''''Boot sequence:'''''
* ROM bootloader loads and execute primary bootloader based on eFuses configuration (SPI/SD)
* Primary bootloader (SPI/SD) with set i.MX6 register to overwrite primary boot device and will reset SOC
* ROM bootloader will load and execute bootloader from newly configured boot device (SATA)

 Configuring primary (SPI/SD) bootloader. Changes are applied in uboot environment:
<syntaxhighlight lang="bash">
setenv bootcmd 'bmode sata'
saveenv
reset
</syntaxhighlight>

Configuring chainloaded (SATA) bootloader:
<syntaxhighlight lang="bash">
setenv sataroot '/dev/sda2 rootwait rw'
setenv sataargs 'setenv bootargs console=${console},${baudrate} ${extra} ${video} root=${sataroot}'
setenv sataboot 'echo Booting from sata ...; run sataargs; if sata init; then fatload sata 0:1 ${loadaddr} ${image}; fatload sata 0:1 ${fdt_addr} ${fdt_file}; bootz ${loadaddr} - ${fdt_addr}; fi'
setenv bootcmd 'run sataboot'
sata init; saveenv
boot
</syntaxhighlight>

== Performance comparison ==
The transfer speed differences between SD card and SATA module are listed in the table below . The test was performed using flexible I/O tester:
<syntaxhighlight lang="bash">
