Use the procedure documented below to install the U-Boot firmware, Linux kernel and filesystem images to the eMMC on the STM32MP1 module. Having completed the installation, the STM32MP1 SOM will boot to Linux from the eMMC on next reset / power on.
Note that the procedure will erase all data previously present on the eMMC.
Here is the installation procedure:
Follow the instructions in the Section 5 of https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package#Installing_the_STM32CubeProgrammer_tool to install the STM32CubeProgrammer Tool to your host.
Add

Attach the miniUSB (for SOM-BSB) or microUSB (for STM32MP1-SOM) cable to connector P5 of the BSB and to the Linux host.
Power on the board, attaching another miniUSB cable to connector P3 (for SOM-BSB) or USB-C cable to connector J10 (for STM32MP1-BSB).
Check that the programming USB port (DFU interface) appeared on the host (note the "Device Index" in the output):

Select the eMMC as the boot device (see in Selecting Boot Device).
Connect miniUBS to P3 (for SOM-BSB) or USB-C cable to connector J10 (for STM32MP1-BSB), this powers the board on.
Connect to the serial console (see Setting Up the STM32MP1 SOM Starter Kit) and see the system booting:
