Hi Based on the user_irq.c I created a simple test program for my PPC405GPr board.
We have a FPGA which generates an interrupt every millisecond. It seems to work as simple test (fire it once and assure that it sets the interrupt-bit). When I connect it to the irq_server however (letting the main task sleep 1 second) I get around 2321964 error and not a single OK from rt_intr_wait. Also my debug LED flicker very fast. The FPGA is connected to the External Interrupt 0, which has the number 25. I think that I either got the polarity/level/edge register wrong or I am playing with the wrong interrupt. Could anybody tell me, whether I used the correct interrupt number? Does Linux somewhere overwrite the values for the UIC polarity/level, etc settings written by U-Boot (e.g. for my board in board_early_init_f) Any hints are welcome.
