M.2 to 4x SATA Module

SATA disk modules provides reliable storage. There are multiple benefits for using them:

iMX8M Industrial Development Kit can use SATA disk to store files
sizeable capacity
available in extended temperature range
Mean Time Between Failures exceeding 1000000 hours
supports wear levelling, SMART and power failure management for data integrity

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

Voipac designation	Manufacturer	Model	Capacity	Flash type
iMX6 Rex SATA Disk Module (default)	Apacer	APSDM008GB2AN-ETM1	8GB	MLC
iMX6 Rex SATA Disk Module 32GB (upon request)	Apacer	APSDM032GAETN-5ETMGW	32GB	MLC

Partition layout

This partition is designed for SATA modules acting as a booting device:

Partition type/index	Name	Start offset (Sector)	Size	File system	Content
N/A	BOOT Loader	1 KB (2)	1 MB	N/A	u-boot-imx6-rexsata-2.4.imx
Primary 1	Kernel	8 MB (16384)	32 MB	VFAT	zImage-imx6-rex-2.4.bin,zImage-imx6-rex-2.4.dtb
Primary 2	Rootfs	Follow Kernel	-	EXT4	fsl-image-gui-imx6-rex-2.4.ext4.gz

Creating partitions

/dev/sdX represent SATA module node which is usually /dev/sda on iMX6 TinyRex Development Kit. Sector size is 512 Bytes.

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:

setenv bootcmd 'bmode sata'
saveenv
reset

Configuring chainloaded (SATA) bootloader:

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

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:

fio --loops=5 --size=100m --filename=/home/root/fiotest.tmp --stonewall --ioengine=libaio --direct=1 \
   --name=Seqread --bs=1m --rw=read \
   --name=Seqwrite --bs=1m --rw=write \
