[FAQ] J7200XSOMXEVM: Unable to connect to cluster-1 of MCU R5F and Main R5F in No-boot mode from CCS debugger

Part Number: J7200XSOMXEVM
Other Parts Discussed in Thread: DRA821

After loading the Gel script as described in PSDK RTOS in No Boot Mode, I am unable to connect to the MCU_R5F_0_1 and Main_R5F_0_1 cores.

  • By default, the GEL script available in CCS configures the R5F cores in lock step mode, which means one can connect to only cluster-0.

    When we attempted to connect to the MCU_R5F_0_1 and Main_R5F_0_1 cores using the CCS debugger, we were unable to halt the cores and establish a connection, as R5F cores are configured in lockstep mode.

    To connect to the MCU_R5F_0_1 and Main_R5F_0_1 cores, we need to configure the R5F cores in split mode, which requires updating the GEL file.

    Please find the updated GEL file for reference to configure MCU_R5F_0_1 and Main_R5F_0_1 cores in Split mode.
    7607.J7VCL_SI.gel
    Please update the GEL file located at "/ti/ccsxxx/ccs/ccs_base/emulation/gel/J7200_DRA821/" with the above one, and relaunch the CCS.

    Changes for reference:
