Hello All,
I'm currently developing a RTNet RTDM driver for the chip SMSC
Lan9221. But I have some problems to make it work ! So I followed the
porting guide for programmer on the RTNet website. The read / write to
register seems to be ok. You can find out the log below.
And the problem is the interrupt management is not working at all.
That's the function call inside the drv_probe: retval =
rtdm_irq_request(&pdata->irq_handle, dev->irq, smsc911x_irqhandler,
RTDM_IRQTYPE_EDGE | RTDM_IRQTYPE_SHARED, dev->name, dev);
