* U-boot: 2016.03
* Linux Version: 4.1.15 ([[SDV04_Embedded_Linux_Kit_(SDVX)#SDVX_software_components | BSP]]).
* root file system: development rfs (bz2 tarball to be extracted around 292MB)
The [[SDV04|SDV04]] boot from an microSD card inserted on the Carrier board slot. U-boot is properly configured to reduce the waiting time and just boot loading the binary images from the storage device.
* SOC: NXP i.MX6 UL
* Flash storage: 128 MB SLC NAND
* U-boot: 2016.03
* Linux Version: 4.1.15 ([[SDV04_Embedded_Linux_Kit_(SDVX)#SDVX_software_components | BSP]]).
* root file system: minimal Qt5 rfs (bz2 tarball to be extracted around 42MB)
The [[SDV04|SDV04]] boot from the SOM's onboard NAND flash . U-boot is properly configured to reduce the waiting time and just boot loading the binary images from the NAND device once the UBI fs parameters have been correctly passed to the kernel command line.
