Code-Compose Studio V4.1 Identifies the TMS570LS20216 as "BE-8" but the device should be "BE-32".

According to the product documentation, the device should be running in BE-32 mode.

However, CCS v4.1 (with XDS100v2) shows "ARM | BE8 | SPV" when I connect.

Why is this, and should I build code using the BE8 or BE32 option for this target?

    Anthony,

    all TMS570 at the moment support big endian. The format that is supported is BE-32. The target status shown in CCS4.1 seems to be wrong. This issue is already known and should be fixed already. 

    I forwarded your observation to the s/w department and asked for a fix, in order to make CCS4.1 display the correct endianism.

    Said this you should use the BE-32 linker option to generate code for the TMS570.

    Is this answering your question?

    Best Regards,

    Christoph

    Hi Anthony,

    Can you open the expression view and enter REG_ENDIAN and see what the value is?

    The status indicator uses these values to indicate the endianess of your target:

    1) (REG_ENDIAN & 0x3) == 0 => LE
    2) (REG_ENDIAN & 0x3) == 1 => BE8
    3) (REG_ENDIAN & 0x3) == 2 => BE

    Regards,
    Patrick

    Yes - thanks Christoph.   Using BE-32 linker option works.

    Patrick,


    I wasn't sure about the expression view - didn't see any menu item with this name.

    But if I type in the 'Watch' window the name "REG_ENDIAN"  it returns the value of 0x0000001.

    If this value originates from a register inside the Cortex-R4F then it is possible that it would read BE-8,

    because the endian correction to BE-32 (ARM7TDMI compatible BE) is done outside the CPU on

    the TMS570 family.  

    Best Regards,

    Anthony
