Hello,
I'm trying to use the memory re-mapping capability in the Amba Designer Network Interconnect tool but I can't (yet) find any documentation on how to generate a NIC-400 with more than one memory map.
In the 'address view' window I can create my memory map no problem but I want to be able to create a second map, almost identical to the first, but with one range removed. The reason is that I want to be able to program the GPV to choose the second map so that a specific target is removed from the memory map which would force the NIC-400 to send an error response to any accesses to this region of memory.
Anyone know how to do this?
Cheers?
Alastair
Hello Alastair,
The answer can be found in the following document:
<AMBA Designer installation dir>/ADCL/doc/DSU0018H_nic400_r1p0_supp_adr400_ug.pdf (Depending on your NIC-400 version, the file name may be slightly different.)
In the above document, there is a section titled "How to hide an address range". It should resolve your concern.
Regards,
Xingguang
