You should use signal tap on your component and check that it is working correctly. I'd advise also not to use the chipselect. It is recommended to only use the read and write signals instead, which are only asserted when reading or writing your component.

The macros you use are designed for the PIO component. You can use the more generic IORD and IOWR macros to access your component. (but this isn't the case of your problem, as the two macros you use are actually using IORD and IOWR on the register 0).
