esp8266 uart communication

Hi,

i am trying to make a uart communication between my FPGA board(DEV0-CV) and esp8266(WIFI module). according to my simulation the UART implementation is working good and i can see the right results. when i upload the design in the FPGA i dont get the right rx data , i tried to debug the design using the logical analyzer and signal tap II but i didnt reach any thing. i have been debuging for almost a month and half without getting any results.

i will be really happy if someone would help me.

N:B i attached the code just if you want to look at it.

regards
