ERC32 clock counter incorrect

[manuel.coutinho at edisoft.pt (Manuel)]

Hi

 

We have discovered a bug in the ERC32 clock driver (at least for the RTEMS
4.8.0 version).

 

Currently, the RTC counter is being initialized with (on the ckinit.c file)

 

 

ERC32_MEC.Real_Time_Clock_Counter = \

      BSP_Configuration.microseconds_per_tick;

 

 

This way it is adding an extra microsecond for each clock tick.

The correct set value should be

 

ERC32_MEC.Real_Time_Clock_Counter = \

      BSP_Configuration.microseconds_per_tick - 1;

 

 

the other SPARC BSPs (leon2 and leon3) clocks seam ok :)

 

 

Kind regards

Manuel Coutinho
