2.3 Boot Mode Setting
i.MX6 CPU boot process begins at Power On Reset (POR) where the hardware reset logic forces the ARM
core to begin execution starting from the on-chip boot ROM. The i.MX6 Boot ROM code uses the state
of the internal register BOOT_MODE [1:0] as well as the state of various eFUSEs and/or GPIO settings to
determine the boot flow behaviour of the device.
i.MX6 Pico ITX SBC supports Boot Mode Switch (SW4) which is physically located in the top of the PCB.
This Switch is used to select the boot mode setting of i.MX6 CPU as explained in the below table. SPI
Flash used as Default Booting Media.
