Unable to handle kernel paging request at virtual address 4003c010

[ManiS]

Hi ,

We are getting this error while running userwaveapp application on Z7, what is the configuration we are missing ? anything to be given in bootargs or system-user.dtsi for Z7 ? 

4003c010 Address is related to a fpga reg for gpio ...

 

fpga_rev7:/usr/bin$ sudo su

any clues or idea team ? is there anything to be done for allocating memory for kernel or set values for  kernelLoadAddr , dtbLoadAddr?

Any  memory setting needs to be done for eclypse Z7 board as shown below picture?

in System-user.dtsi i have put the following 

setenv bootargs console=ttyPS0,115200 earlyprintk root=/dev/mmcblk0p2 rw rootwait/;load mmc 0 ${kernel_load_address} zImage/;setenv bitstream_image system_wrapper.bit.bin/;load mmc 0 ${loadbit_addr} ${bitstream_image} && fpga loadb 0 ${loadbit_addr} ${filesize}/;load mmc 0 ${devicetree_load_address} ${devicetree_image}/;bootz ${kernel_load_address} - ${devicetree_load_address}
