Reassy problem with LS2088 AIOP

Question asked by Wille Kuutti on Nov 8, 2019

Hi,

 

I'm trying to implement hardware assisted reassy on LS2088 AIOP. It is now working stable with low data rates (few hundreds of megabits per second), but when using higher data rates I got these kind of errors and the datapath freezes:

 

> MAJOR [CPU 7, exception_handler.c:57 exception_handler]: Fatal error encountered in file: fdma.c, line: 365
> MAJOR [CPU 7, exception_handler.c:58 exception_handler]: function: fdma_modify_default_segment_data
> MAJOR [CPU 7, exception_handler.c:59 exception_handler]: error: Invalid Segment Handle.

> MAJOR [CPU 7, exception_handler.c:57 exception_handler]: Fatal error encountered in file: fdma.c, line: 365
> MAJOR [CPU 7, exception_handler.c:58 exception_handler]: function: fdma_modify_default_segment_data
> MAJOR [CPU 7, exception_handler.c:59 exception_handler]: error: Invalid Segment Handle.

 

Any ideas?

 

The same error appears with both internal and external timers and independent of the reassy table and timer memory placement (system-DDR and PEB).

 

Br,
