Hello,
I'm doing a small RT application using the I2C driver from Linux. At a certain time, when the task is activated and data are written to the I2C bus, the driver waits for a IRQ that confirmed the data have been sent out. The write function actually polls a variable state until a timeout or a state change occurring on reception of that IRQ (done by the handler). However, since driver functions are called from the Xenomai domain, the IRQ handler is not processed at the reception since the hander belongs to the Linux domain. It ends up with a timeout during the write. I implemented a local ISR within the Xenomai application, but the propagation of IRQ is not performed while the task is running. Is there a way to tell Adeos to forward the IRQ to the Linux domain with no delay so that the Linux handler can be called? or do I need to re-implement the ISR in the Xenomai application? Thanks for any hints. Daniel
