Where does tf-a-stm32mp157d-ev1-usb.stm32 come from ?

[JSchn.5]

Our hardware has an STM32MP151DAx.

In order to make use of the Cube Programmer and the boot-via-USB method I need the equivalent of the tf-a-stm32mp157d-ev1-usb.stm32 file but for our hardware.

I have worked through the IOC stuff, have DTS files and got the hang of building TF-A (and U-Boot and Linux) according to instructions but how do I build this -USB variant as used in the .TSV files ?

Hi @JSchn.5​ ,

I'm not expert, but did you follow https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#TF-A_-_regenerate_TF-A ?

The "xxxx-usb.stm32" bianry is generated during make with TF_A_CONFIG="optee emmc nand nor sdcard uart usb" option (could be tailored to your needs if you only need some flash flavors)

Regards.
