The Emcraft STM32MP1 Starter Kit supports several boot devices. Selection of a specific boot device is defined by the state of the jumpers on the JP10 header of STM32MP1-BSB, as described in the following section.

1. Selecting Boot Device on STM32MP1-BSB

Selection of a specific boot device is defined by the state of the switches on the STM32MP1-BSB development board, as follows:

State ON means presence of a jumper on the corresponding pin of the JP10 header; state OFF means absence of a jumper.

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 STM32MP1-BSB, as described above.

Refer to the following additional information on how to boot from the various devices:

• Booting Linux from SD Card
