Dear Aneesh V,

I am finding it difficult to implement this using the struct based approach. I tried the sample code below:
struct my_regs_struct { const unsigned int reg1; const unsigned int reg2; const unsigned int reg3; };
The const for structure fields above were not intended. I put them while debugging this issue and forgot to remove later.
static struct my_regs_struct *const my_regs = (struct my_regs_struct *)0x1000;
static unsigned int *const reg_arr[] = { &my_regs->reg1, &my_regs->reg3 };
void main(void) { printf("regs %x %x \n", reg_arr[0], reg_arr[1]); }
Sorry, but I fail to understand the problem. Why is reg_arr[] needed? Why don't you use
struct my_regs_struct { const unsigned int reg[3]; }; ?
I want a number of register addresses in an array - an array of constant pointers. The array is populated at compile time with the addresses of all the modules that need to be initialized. At run-time I do a specific operation on all the registers given in this array.
best regards, Aneesh
