4.14.1 SPI Device Header
The conga-SMC1 provides connector X36 for external BIOS flash (boot from carrier SPI). With the SPI BIOS flash, you can evaluate a custom
BIOS or load BIOS/bootloader default settings (recovery). However, you need an SPI flash with a PCB adapter that connects to X36. For more
information, contact congatec support.
To select X36 as boot source, set DIP SW4.4 to ON position. For more information about boot selection, see section 4.15 “Boot Selection
Switch”.
