TMS320C5517: How to access the DSP's DARAM area(0x00c0~0x10000) from external host with UHPI?

Hi,

I can write and read data from C5517's SARAM area( >= 0x10000 ) from external host with UHPI, but If I write and read data from  the DSP's address less than 0x10000(DARAM area),  it will return 0 if read.  How can I access this area from external host?

Best Regards,

Dudechao

    Hi,

    Our UHPIA register is setting as:

    (SARAM_byte_address+0x8000)/4. when read or write.

    I want to konw if the UHPIA register is set as (DRAM + 00x10000)/4 when access DARAM(0~10000)?

    I try this,, but it is still return 0 when read.

    If the DARAM can not be wroten, how to boot loading the program  from UHPI?

    I

    Best Regards.
