Selecting Boot Device Print


The Emcraft STM32MP1 Starter Kit supports several boot devices. Selection of a specific boot device is defined by the state of the switches on the SOM-BSB development board, as follows:

SW4.1 SW4.2 SW4.3 SW4.4 SW4.5 SW4.6 SW4.7 SW4.8
Boot from SD Card OFF OFF OFF ON ON ON ON ON
Boot from on-module eMMC OFF OFF ON OFF ON ON ON ON
Boot from USB Serial Downloader - - OFF OFF - - - -

By default, the Starter Kit is configured to boot the default Linux configuration from the on-module eMMC. You can override this configuration by modifying the set of the switches on the SOM-BSB, as described above.
