Hi,
I am working with 2010R1 distribution and tool chain for BF527 custom board. The board is having IR receiver connected to the PortH 13 of BF527.. i have configured the PH13 of bf527 as gpio for input and interrupt configuration to both edge using the following function...
if (bfin_gpio_request(GPIO_PH13,"IR")) {
return -EBUSY;
}
gpio_direction_input(GPIO_PH13);
set_irq_type(IRQ_PH13,IRQF_TRIGGER_BOTH_EDGE);
/*Request IRQ_PG13 for IR*/
s32_RetVal = request_irq(IRQ_PH13,(void *)IR_IRQ_Handler,IRQ_DISABLED, "IR_IRQ",NULL);
while runing with standalone application for remote key detection it display the following things when ever pressing the remote key.............

I have refered this document but i didn't get anything from that document .. and one more thing to ur note is if i am writing the folowing thing directly , then no problem with this one,
s32_ReadVal=bfin_read_PORTH_FER();
bfin_write_PORTH_FER(s32_ReadVal&0xDFFF);
asm("ssync;");
can i use in this way or i need use gpio request API ? help me..................
