I'm working with Montavista Linux 3.1 Embedded Development Kit( pro ) on Motorola M9328MXLADS Evaluation Board( has i.MX1 DragonBall Application Processor on it ).
I'm using NFS Cross Compile.
When I'm trying to debug my code( via Telnet ) the following announcement appears:
#define DDIR_A (*(volatile unsigned int *)(0x0021C000) // Absulote address
DDIR_A = 0x00000004; // Output signal
Could someone help me? I have heard on "mmap" fuction, is it could be helpful?
