TMS320TCI6608: Question on corepac L1D tag ram

Part Number: TMS320TCI6608

Hi expert,

Customer used TCI6608 and found protected address error on one DSP. The offset of fault address is always 0x880. We checked assembly instructions and registers  this error issued. So we wonder if there is something wrong in the tag ram in L1D cache. But L1D cache tag ram is invisible from DSP side. So customer asked

1. Does DSP have EDC on L1D cache tag ram?

2. Is there any method to check tag ram?

Thank you.

Regards,

Allen
