I have a QSYS design in which the peripherals do not appear to be decoded correctly. They work fine when controlled by System Console through the JTAG port, but not when controlled through the I2C port.
My design includes a QSYS system with the following components:- JTAG to Avalon Master Bridge
- Altera I2C Slave to Avalon MM Bridge
- 3 x Altera PIO (at addresses 0x0 to 0x0f, 0x10 to 0x1f, 0x20 to 0x2f)
- 4 x quadrature encoder counter (my designs; at 0x30 to 33, 0x34 to 0x37, 0x38 to 0x3b, 0x3c to 0x3f)
