Is it possible to debug the STM32MP157 with ST-Link? I have the STM32MP157A-DK1, and am working with a VirtualBox Ubuntu system with the CubeIDE. We really do not want an ethernet port on our final product.

There are many different levels on debugging possible on STM32MP157, here is an overview: https://wiki.st.com/stm32mpu/wiki/STM32MP1_Platform_trace_and_debug_environment_overview

In a final product, you won't do typical bring-up tasks close to hardware and schematics level but rather want Linux debugging tools for developing/updating at the Linux file/application/kernel level.

Network access could be done via an external USB/Ethernet adapter on an USB port if you prefer.

Check also AN5031Application note for HW development.
