hi,
I get a problem when I develping a driver with MPC8540.
The hardware cannot set the interrupt line register. So, the Interrupt
resource cannot be recognized by driver. In the dirver source code, I had to
intialize an interrupt object with another form using IRQL, VECTOR
allocatted by myself.
The driver could be installed successfully, But when an DMA transfer was
finished, the dirver could not receive the interrupt. when I checked the
information about interrupt registers, they all works well, and show that
interrupt had been outport to system. but, driver cannot get it…
