I am writing a custom driver for SPORT0 to work in standard serial mode of BF609.
I have enabled interrupt for SPORT half A using
'request_irq(IRQ_SPORT0_TX_STAT, (void *)my_handler,IRQF_DISABLED,NULL);'
as IRQ_SPORT0_TX_STAT is the IRQ number for SPORT half A
and my interrupt handler as
static irqreturn_t my_handler(int irq,void * dev_id,struct pt_regs *regs)
printk(KERN_INFO"interrupt");//debug message to ensure interrupt occurs
but i never get the message.
SPORT half A is configured in receive mode , external frame sync, external clk and SLEN as 8-bit.
