    As per device data manual,

    The 1MB OSR is added to the device for:
    • QMSS External Linking RAM
    • NetCP1.5 intermediate data buffer
    • Intermediate buffering of other data storage

    The OSR supported features include:
    • SRAM supports ECC with Read-Modify-Write logic
    • RTA memory
    • Support interrupt for ECC error event
    • Support Little and Big-endian modes of operation

    OSR does not support any type of cache access, hence this memory space must always be marked as non-cacheable region for both DSP and ARM cores.

    Can you please elaborate your query? I will look for additional information and post back if i find it. Thank you.

    We do not have user’s guide because it is just a memory.

    Thank you.

    Hi Rajasekaran,
    Sorry for late reply.
    In Table 7-1. Device Memory Map Summary for 66AK2L06, page 61, there is some OSR configuration registers. I want to know more details about that OSR configuration. I think that OSR configuration contains some control information about ECC, etc. Thanks

    Hello Chas,

    OSR config space seems to be missing the documentation.

    The register contents in that address region are identical to E CC submodule registers for GbE switch module.


    www.ti.com/.../getliterature.tsp
    3.5.6 ECC Submodule


    Please use the above as reference while we get the documentation updated.

    THank you,
