Problems patching devicetree

[Chris_Leyson]

Hi everybody

I've encountered a small problem when running make FPGA_TOOL=vivado image, I get a permission denied error when patching devicetree.dts, fpga and sw_package build without any problems.

Code: Select all

source /opt/Xilinx/Vivado/2013.3/settings32.sh
export CROSS_COMPILE=arm-xilinx-eabi-
make FPGA_TOOL=vivado image

make -C image/ FPGA_TOOL=vivado -k all
make[1]: Entering directory `/home/chris/RedPitaya/FPGA/release1/fpga/image'
cp ../vivado/red_pitaya.runs/impl_1/red_pitaya_top.bit out/fpga.bit
cp ../vivado/red_pitaya.sdk/SDK/SDK_Export/fsbl/Debug/fsbl.elf out/fsbl.elf
bootgen -image out/boot.bif -w -o i out/boot.bin
cp ../vivado/red_pitaya.sdk/SDK/SDK_Export/device-tree_bsp_0/ps7_cortexa9_0/libsrc/device-tree_v0_00_x/xilinx.dts out/devicetree.dts
patch -N out/devicetree.dts src/device_tree_vivado.patch
patching file out/devicetree.dts
src/dtc -I dts -O dtb -o out/devicetree.dtb out/devicetree.dts
make[1]: execvp: src/dtc: Permission denied
make[1]: *** [devicetree] Error 127
make[1]: Target `all' not remade because of errors.
make[1]: Leaving directory `/home/chris/RedPitaya/FPGA/release1/fpga/image'
make: *** [image] Error 2

I'm running Ubuntu 14.04 alongside Win7 and I'm fairly new to Linux so I may have missed something.
Any help would be appreciated.

Regards
Chris

Patching is not your issue here, the dtc call is,
have you installed the 32bit ubuntu version? The dtc executable in the FPGA/release1/fpga/image/src directory is 64bit, that may be the problem.
If you are running a 32bit OS you need to build yourself dtc (don't have time right now to explain the steps, tell me if you need further help).

Thanks melko

Reinstalled Ubuntu (32-bit version) together with all off the required packages.
Installed device-tree-compiler and copied dtc from /usr/bin to fpga/image/src
Seems to have fixed it.

Code: Select all

sudo apt-get install device-tree-compiler
sudo rm /home/chris/RedPitaya/FPGA/release1/fpga/image/src/dtc
sudo cp /usr/bin/dtc /home/chris/RedPitaya/FPGA/release1/fpga/image/src
cd /RedPitaya/FPGA/release1/fpga/image/src
sudo chown chris:chris dtc
sudo chmod 700 dtc

Also installed on a 64-bit machine and everthing builds without any problems apart from the speed, very slow.

I noticed that on my 32-bit laptop the file permissions in image/src are different, they're -rw-------.
Perhaps a fresh clone is in order.
