PC9 is somewhat strange. If I set it to 0 I don't have a console!
can you please ask at taskit what function this pin has and document it here?
I'm already waiting for an aswer ...
So I tried to put both
| at91_set_gpio_output(AT91_PIN_PC9, 1); | at91_seriald_hw_init();
into board_early_init_f() to avoid the strange characters at boot time, but again no console output ...
Further tests showed that It seems that I can't use at91_set_gpio_output() inside board_early_init_f(). Switching on the red LED with PC5 also do not work in board_early_init_f() ...
Any ideas?
Not currently. Maybe the PC9 has some vital functionality for UART to work (some switch, power, ...) and is reset by another part running after board_early_init_f()?
But how can I reset this PIN without using 'AT91_PIN_PC9'? I'm grep'ed all over the source code but don't find nothing! Is there another way of setting the PIO pins?
