I've solved my problem by changing new cableLOL! If it were not for the 3 way tag team we've created, things might be differentI appreciate the respites, much appreciated.
Case in point @Djsarakar , It would be really nice to know if you got the terminal echo working before going off in some new task with new IO code and a host of new errors. That is ..uhh.. frustrating, for me at least, because I never quite know where things are and I don't like solving the same problem more than once.
I'll leave it here for now, carry on and good luck!
I wrote the LED test program because I was not sure that whatever I typed on terminal I am getting it back. Sometimes I was getting what I was typing and sometime I wasn't getting back what I was typing.
I wrote and posted the LED program in a hurry, then went to the shop to buy new serial cable. Changing the cable solved my problem
I've trouble with development board. Even before this the LCD was not working due to jumper wires. now I have directly mounted the LCD on the board I have solder and de soldered the pull up resistor many times on the board to run RTC.
Here is working program for LED I've written and It works as I wanted. you can test @hexreader on your board
