I'm trying to use local address while writing from PRU and use global
address while reading from host C prog. Proper global and local address
schemes for local mapping and global mapping of the 12KB shared memory is
what I'm confused about.
/* in PRU code */
float *a;
a = 0x1000 /*local memory mapping of 12KB memory */
*a = 1;
'a' will be incremented in a loop whenever a particular GPIO pin is toggled
i'm confused about global mapping of the 12KB memory to access it from
host C at regular intervals of time.

You may use prussdrv_map_prumem(...) to map PRU memory to host (C-client)
utility.
If no pin state change, first of all you should show us your pin mux
settings of the respective pins.
