printf through uart
Thanks M Schultz and Bernard,
once again this forum is effective and operative.
Your suggestions works on my platform, both copy and paste code from Schultz or drag syscalls.c file from AC6 files template folder, and of course implementing low level read/write routines. For using syscalls.c, I have to insert also lines:
setvbuf(stdin, NULL, _IONBF, 0);
setvbuf(stdout, NULL, _IONBF, 0);
setvbuf(stderr, NULL, _IONBF, 0);
(as suggested by Schultz) on my init procedure to let library works properly and see my printf on terminal.
Now my printfing goes straight ahead
Thanks again
