Hi, Is the recognition of IAAS a hardware interrupt (according to manual, yes)? I set IEN (I2C enable) and IIEN (Interrupt Enable). I set the slave address to 0x1c (chosen at random). The IMX bus driver is unchanged. With my external Master I ask for the address on the bus. But the IAAS bit is never set. In this test, I want to see if the hardware interrupt work. Should i modified the bus driver (IRQ handler???) or is this a real hardware interrupt? Where is my misconception?
