Hi All,
=20=20=20
I had written a simple C program for M68HC711E9 Controller using Freeware=
GCC version 3.3.6. Also i compiled using GCC with vectors.c file and Linke=
r file memory.x
=20=20=20
I generated the .S19 using GCC compiler and flashed it to 68HC711E9 using=
EVBplus2 development Board. But the C Code is not working, its not display=
ing the LED in Port B.
=20=20=20
The C Code and Memory.x (Linker command file) is as below: Please tell me=
is there any problem in C code or Linker command file (memory.x) or What m=
ight have caused the problem that LED is not blinking..?

Your question is really about a specific toolset, not the processor.
I suggest you post over on the GCC for MC68HC11 mail echo. People
over there are more likely to be able to help you.

Also, I suggest that you not post three times the same message. It's
annoying.

To try to give you some response which is related to the '11,
are you sure you are booting into the proper mode? If you boot
in expanded mode, then you don't have a PORTB.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
