Check your MMU config, uboot do not init MMU??so you can access all address.

Subject: RTEMS FPGA memory access failed
Hi,
I have a DE0 Nano SoC (Cyclone V) board that runs rtems 4.11. When RTEMS
accesses the FPGA memory space (0xc0000000 - 0xfbffffff) via the
HPS2FPGA AXI Bridge by using command - mdump, the system got reset and
failed. The FPGA is programmed and the HPS2FPGA AXI Bridge is working.
The U-boot can access the FPGA memory address starting 0xc00000000. Does
anyone knows why rtems can't access the FPGA? and how to solve it.
Thanks
Jay
