Honored ContributorHi,
when you generate your Nios, either with the sopc builder or qsys, you'll get a so called sopc.info file which you initially used to build your BSP. So if you now change anything in your Nios, you have to overwrite this initial sopsinfo file, if it isn't done automatically, and then right click on the BSP in the eclipse's project explorer and under the menu "Nios II" there should be something like Generate BSP ... Maybe try this. But you said sometimes you can access periphal, so you should be fine there. Are your problems dependant from the system up time => FPGA gets warm? Or do you get these problems also right after power up?
