Hi folks, I use Atmel AT91SAM9260-EK boards, arm-linux-gcc (GCC) 4.2.4. After I pulled the latest code from git://git.denx.de/u-boot-at91.git, I found that the "weak" function seems not working.
In lib_arm/board.c, we can see, void inline __coloured_LED_init (void) {}
void inline coloured_LED_init (void) __attribute__((weak, alias("__coloured_LED_init")));
And then I defined my own version in board/atmel/at91sam9260ek/led.c, void coloured_LED_init(void) { //.. do someting... }
After 1)make at91sam9260ek_config and 2) make 3) download the u-boot.bin to dataflash 4) reseting the board, I found that my version of coloured_LED_init never gets called. Could anyone please explain the trick behind?
BTW, If I comment out the declaration in lib_arm/board.c, my version of coloured_LED_init can get called.
Thanks.
