Boot Mode (S4)

Figure 16: Boot Switch S4

The pyhBOARD-Regor has two defined boot sequences which can be selected with DIP
switch S4.

Boot Mode

Description

Boot mode 1 (S4 = OFF)

SYSBOOT[4:0] = 10011b

→

NAND, NANDI2C, MMC0, UART0

Boot mode 2 (S4 = ON)

SYSBOOT[4:0] = 10111b

→

MMC0, SPI0, UART0, USB

System Reset Button (S2)

Figure 17: System Reset Button S2

The phyBOARD-Regor is equipped with a system reset button at S2. Pressing this button

will toggle the X_nRESET_IN pin (X64A11) of the phyCORE SOM low, causing the module to

reset. Additionally, the reset signal nRESET_OUT is generated on the module and will also

reset the peripherals on the carrier board.
