C6455 SRIO Direct IO error

Started by feng...@gmail.com February 10, 2011
Hello,
I use SRIO NWRITE_R mode to write data to 6455 Dsp0 L2 RAM from 6455 Dsp1.

different destination address LSB (the left column) and diffrent byte count (the first row), with the results (S-success, F-fail):

1 2 3 4 5 6 7 8 9+ (bytes)

0 S S S S S S S S S

1 S F F F F F S S S

2 S S F F F S S S S

3 S F F F S S S S S

4 S S F S S S S S S

5 S F S S S S S S S

6 S S S S S S S S S

7 S S S S S S S S S

When failed, the error code is: 100b-Transaction complete, packet not sent due to unsupported transaction type or invalid programming encoding for one or more LSU register field (from spru976)

Can any one show me the reason? Thanks!
