Hi everyone,
System: C6713 Device cycle accurate simulator ( CCS3.3)
-> Simulates C6713 processor
-> Supports L1P, L1D, L2 Cache, EDMA, QDMA, Timer(2), EMIF interfacing
with async and SDRAM Memory models, McBSP(2), interrupt selector.
My system: EDMA configured to acquire data in ping pong buffers mapped in
external memory. A timer event is used to produce EDMA interrupt. In one sec
ping pong slot, i intend to process the acquired data. processing involves fft,
swt, filtering etc.
Note that except the ping pong buffer and constants, everthing is mapped in L2
(256k, no cache is configured)
As far as compilation goes, it is ok.
But while i run the code it gives the following errors:
Error: Memory Map Error: READ access by CPU to address 0x4e7dd240, (AHPIPCI
Queue Space) which is NOT SUPPORTED in Simulator.
...
...
Error: Memory Map Error: READ access by CPU to address 0x3ef2d22c, which is
RESERVED in Hardware.
...
...
Error: Illegal opcode (c47a0000) at pc = 0x00020260
...
...
>From the memory map it is apparnet that 256kbyte is
not good enough for th
e system to run

Can anyone give any suggestion what could be done. I have 8Mbyte of external
memory and i have used only frction of it. What would be the best map i can do
to use the external memory. Now i use the external memory to store my all
constants as well. Pls note that i have once tried to map code (.text) in
external memory. I got the same error. I do not know what is wrong.
any help would be appreciated. Thanks
