Hi Slide,

So, does this mean that you have some new untested H/W and and a fresh
eCos port for it or your port closely depends on some known target in
eCos World?

Good news, at the least you managed a polled (non-interrupt driven)
diagnostic *output* for the UART, and as you say that diag_printf()
works smoothly, then try the simplest diagnostic *input* with

  HAL_DIAG_READ_CHAR(_c_) macro

BUT,

It's good to know, How you download and run your test printf(), gets()
application? Do you share diagnostic and debug channels on that UART or
use an alternate communication channel for testing (debugging)? If you
use GDB remote protocol via that serial port..., well I won't guess,
write a bit, please, about your startup and debug environment.

Let's leave this a while, especially gets().
