I'm still not happy with that. What I had in mind was more or less:<br>
<br>
<br>
static void output_char_serial(char c)<br>
{<br>
arm_pl011_write_polled(&pl011_context.base, c);<br>
}<br>
<br>
static void output_char_fb(char c)<br>
{<br>
fbcons_write_polled(&fb_context.base, c);<br>
}<br>
<br>
BSP_output_char_function_type BSP_output_char = output_char_serial;<br>
<br>
<br>
And if you decide that the frame buffer should be used in the select<br>
function you do a<br>
<br>
BSP_output_char = output_char_fb;<br>
