https://people.ece.cornell.edu/land/courses/ece5760/de1_soc/hps_intro_54001.pdf See Figure 1-3 http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0246h/chdbgdag.html See the Address Filtering registers https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyclone-v/cyclone5_handbook.pdf See page 9-2 for a diagram of the two ports coming out of the L2, M1 and M0. These are important for the Address Filter registers. See page 7-26 for the remap register The MPU memory map is controlled by several registers: 1) remap register, 0xff800000 2) L2 address filter registers, 0xfffefc00 and 0xfffefc04 It would help if you described more of your setup -- are you using the preloader, the bootloader, Linux, baremetal, what sample projects are you starting from, all of the steps you are doing leading up to point where you see the problem.
