Other Parts Discussed in Thread: OMAPL138

to write registers in Omapl138 I use function

#define SETBIT(dest,mask) (dest |= mask)

where dest is register address and mask is a value that I want to writre.

Previously I used Memory Browser to read registers in CCS.

Now I need some function to read registers to save it's value. How can I do it?

Thnx.

For read the register:
The below piece of code for your reference only.
You have to modify according to your usage of registers.

#include "hw_types.h"
#define EMIFA_MIDR (0x0)

unsigned int baseAddr;
unsigned int modId;

modId = HWREG(baseAddr + EMIFA_MIDR);

2818.hw_types.h

Register successfully read.

Thank you!

p.s.

What's for HWREGBITW(x, b) function?

I thought it is to read register x with offset of b bit, but it's not true.
