Hi everybody,
I'm trying the sobel filter application on zedboard using this link;
http://shakithweblog.blogspot.com.tr/2012/12/getting-sobel-filter-application.html
I have followed the instruction, booted linaro and compile program.
Finally, run the "sudo ./camera" command. program crash on the REG_WRITE function.
On the other hand run the "./camera" without using "sudo" program can work on the arm processor but hardware doesn't work. It acceptable because program can't access the /dev/mem file to run without sudo. I want to run "sudo ./camera" command to access /dev/mem file and access but crash on the register writing.
Where am I wrong?
* I tried some different sd cards and different class. (toshiba class 4 8GB, sandisk class 10 8GB, toshiba class 10 16GB and toshiba class 2 8GB). Every card booted linaro but get the same error.
* I have installed cmake and libopencv-dev after boot the linaro system. Any suggest extra program or library for this problem?
* I'm using gparted for formatting sd card, BOOT partition FAT32 and rootfs partition (file system linaro) EXT4 format.
* Using linaro-precise-ubuntu-desktop-20121124-560.tar file which is 12.11 version.
* I see the error just on the uart terminal. Here is the error on uart:
unhandled fault external abort on non-linefetch (0x818) at 0x0b6...
Any suggestion?
Thanks.
