Hi 

Building a project with the old TI RTOS there was an ability RTOS to "run" on ROM or on FLASH. What is situation with RTOS7 about this ROM/FLASH feature?

    Hi Dimitar,

    Tirtos-7 are compiled in flash, it does not use ROM components.

    Hi Sid,

    It is sad to hear that. For me it is look like that with the RTOS7 the TI has done a regression:
    pros:
    1. Smaller time for project rebuild - but in a bad cases I do rebuid no more then once per day, usualy once per several days.

    cons:
    1. No ability to create RTOS object staticaly - as a result more FLASH and RAM consumption, need to think about alingnment in case of dinamical object construction (not creation), and some initial time to build system after MCU reset.
    2. Not using of the RTOS's ROM components - again more FLASH consumption and some kind of a waste of the MCU available recources (RTOS's components in the FLASH).


    I say all of this as there is no longterm support for SDK and RTOS so in order to maintain SDK support I have to migrate to the RTOS7.

    Seeing RTOS7 development I remember what one not very clever manager said once. Not understanding the issue with one product after several explanation he said - ''O, now I understood - we don't have a problem, the customers have!"
