  • [ABANDONED] RTT on dual core i.MXRT1176

    Hello,
    I am working on a project based on i.MXRT1176, where both M4 and M7 cores are used. The problem is, I can see RTT output only from application running on M7 core.

    Here follows some information about debug setup:
    - Debugging is made via two Ozone sessions (M7 in download, M4 in attach)
    - Each application uses its own RTT control block
    - Address of control blocks is correctly detected by both Ozone instances (and buffer data is ktbg)
    - RTT log from M7 is correctly displayed in M7 Ozone instance
    - RTT log from M4 is not displayed in M4 Ozone instance, nor in RTT Viewer
    - If M7 Ozone session is disconnected, then RTT log from M4 can be displayed in both Ozone and RTT Viewer
    - J-link version 7.88e, Ozone version 3.30

    What am I missing?

    Best regards,
    Stefano

    Additional information
    After disconnecting M7, if I re-attach to M7 core, then I can see RTT log from M4 in the terminal of the Ozone M7 session (although CB address is the one of M7 application).
    If I disable and re-enable RTT in Ozone M4 session, the I see RTT log from M4 in both terminals.
