    Hi,

    We currently do not support creating baremetal application code for C7x. The PDK examples we provide for C7x are all FreeRTOS or SafeRTOS applications - as listed here.

    If you are using the RTOS-SDK default boot flow, you will utilize the SBL (Secondary Bootloader Flow) which runs on MCU1_0 and starts the other cores, such as C7x. You can go through PDK's SBL code and understand this process. 

    The specific startup code for C7x is contained within the CSL and OSAL packages in PDK - you will need to link to these in your application that you create. The supported PDK examples for C7x are a good reference point for this.

    Best,

    Asha
