TMS320F28379D: DSS allow 2 .out's to reside in flash

Diane Haldeman

I have a bootloader that resides in flash sectors A, B.

My application resides in flash sectors C-N.

When I use DSS's com.ti.debug.engine.scripting.Memory.loadProgram() to load the application .out, it erases the bootloader sectors A and B.

How can I keep both .out's in flash for a DSS session? Is there an alternative to loadProgram() that won't erase all flash sectors?

Thank you,

Diane

You can control this by using the DSS Flash APIs to configure the flash options:

<CCS INSTALL DIR>/ccs/ccs_base/scripting/docs/DS_API/com/ti/debug/engine/scripting/Flash.html

Setting the options would work similar to setting the debugger options:

https://software-dl.ti.com/ccs/esd/documents/users_guide/sdto_dss_handbook.html#debugger-properties

Except you would use the Flash APIs instead.

Thanks

Thanks Ki.

This fixed it:

        self.debug_session.flash.options.setString("FlashEraseSelection", "Selected Sectors Only")
        
        # Don't erase the sectors where the bootloader resides
        self.debug_session.flash.options.setBoolean("FlashC28Bank0Sector0", False)
        self.debug_session.flash.options.setBoolean("FlashC28Bank0Sector1", False)
