IWR6843ISK: Boot IWRxxxx chip into the primary boot-loader from application

Dinesh S1

Part Number: IWR6843ISK

Hello Team,

I'm developing an interface in the RTOS application to boot into the primary boot-loader on soft-reset.

As per my study, the MSS R4F processor has been enabled to boot from TCMA region and the MSS_TCMA_ROM section seems to be eclipsed by bootrom code. Only the post-eclipse view with MSS_TCMA_RAM remapped to 0x00000000 is visible to the application.

I would like to disable ROM eclipsing, retain the pre-eclipse view for my use case or restore pre-eclipse view by fetching the ROM code into the TCMA RAM and remap the address table if that is possible.

Could you please suggest on feasibility of disabling the ROM eclipsing in the ROM code via some commands or developer details on fetching the bootrom code into TCMA RAM.

Thanks,

Dinesh

Hi Dinesh,

ROM Eclipsing is performed by the Bootrom itself and hence it is not possible to disable this functionality and/or fetch the bootrom code in software. Could you provide some details on your use case and what you are trying to achieve?

Thanks

Hello Nitin,

Thanks for the reply. Wanted to load a fresh copy of the image into the RAM from the Serial flash from application.

Regards,

Hi Dinesh,

As discussed above, it is not possible to disable ROM eclipsing and fetch the bootrom code in software so I will close this thread.
