Can anyone help me to de-assert the uart interrupt line.
Please read the OMAP3530 TRM. it explains how to handle the UART registers.
I have enabled the UART interrupt only for reception of data.
Processor get the interrupt and data is read to a local buffer. Since the Interrupt line is not deasserted , i keep on getting the same interrupt.
How can i deassert the UART interrupt in OMAP 3530? Is it in the UART side or Interrupt Controller Side?
How does Ubot handle this? How is the Interrupt line cleared in Uboot?
I would recommend doing the following: git clone git://git.denx.de/u-boot.git vim drivers/serial/ns16550.c You'd see that it is not using interrupts, it does a poll on interrupt status register..
