BASIC DA14580 Boot External CPU

Hello MT_dialog,

I use the DA14580 development Kit-Basic and with the AN-B-023 I successfully loaded my project into the Flash memory (W25X20CL) and booted from it using SPI.

Now, I want to connect it to an STMicroelectronics STM32F103R8 using SPI, is it possible to load my project into it's internal flash memory and boot from it as I did with the DA14580 ? Or should I I implement a booting protocol in the ST Microcontroller to send data over SPI to my BLE module (slave) ?

Thank you very much and regards,
