(EDK 8.1.02i)
I have instantiated an OPB Bus/Arbiter around a microblaze wtih the following parameters:
BEGIN opb_v20 PARAMETER INSTANCE = opb PARAMETER HW_VER = 1.10.c PARAMETER C_EXT_RESET_HIGH = 0.02i) PARAMETER C_DYNAM_PRIORITY = 1 PARAMETER C_PROC_INTRFCE = 1 PARAMETER C_BASEADDR = 0x004E0000 PARAMETER C_HIGHADDR = 0x004EFFFF PARAMETER C_PARK = 0 PARAMETER C_DEV_MIR_ENABLE = 0 PORT SYS_Rst = no_reset_sistema PORT OPB_Clk = reloj_sistema END
Well, the problem is that I cannot access the arbiter registers at all.
Where is the problem? Does anyone know? Or is it a Xilinx bug? Or what?
I am really lost, and I am in urgent need of changing bus priorites. Specifically, I need to give higher priority to peripherals than to microblaze.
