Re: [openrisc] Development interface GPR address

Heya !

 

If I understand correctly you ask how bits of GPRs map to debug interface data bus? Well low GPRs order bits map to low order bits of debug interface.

Hi:

 

   In the development unit document you say that with the debug interface you can access internal registers of Openrisc. This debug interface has a ardes bus of 32 bit length. The SPR has directions assigned in Openrisc 1000 Manual but GPR dont have any. What is the direction of those GPR and the others elements accessed by development unit.

 

Thanks
