First of all thanks for the reply. I have already tried with these write and read addresses. The data is not shown at write address. second thing is that the FIFO fill level is not incremented.

In read operation, read back value is always -1 which is wrong. READ FIFO fill level is also not decremented.

FIFO depth is 16. FIFO_0_IN =>address range 0xb00d998 - 0xb00d99b

FIFO_1_OUT => address range 0xbd0099c - 0xb00d99f
