CCS/BEAGLEBK: Build error

Build the PRU Firmware
1. Launch CCSv6 and select the default Workspace.
2. Open the button_led_0 project.
a. In the button_led_0 project, select File->Open File and copy in the resource_table_0.h file from <PRU_SW_PATH>/labs/lab_4 or use Project->Add Files... to add the file to the project and copy it into the workspace.
b. In the AM335x.cmd file, add a line telling the linker where to place the new .resource_table section.

c. In button_led_0.c include the resource_table_0.h file.
#include <stdint.h>
#include <pru_cfg.h>
#include <pru_intc.h>
#include "resource_table_0.h"
d. Rebuild the project and ensure that it builds correctly without errors.
3. Open the button_led_1 project.
a. Select File->Open File and copy in the resource_table_1.h file from <PRU_SW_PATH>/labs/lab_4 or use Project->Add Files... and copy the file into the workspace.
b. In button_led_1.c include the resource_table_1.h file.
c. Rebuild the project and ensure that it builds correctly without errors.
d. You may choose to launch the debugger and verify that both projects run without issues.
Modify Device Tree Files to Account for PRU Cape
The SDK includes example device tree source files for several TI and community boards, like the Beaglebone Black. Since the PRU cape requires certain pin muxing and configuration to be configured to be usable in Linux, this requires modifications to the device tree files.
4. Modify to SDK provided DTS (devicetree source) files to account for the PRU cape.
a. Copy the am335x-boneblack-prucape.dtsi from the <PRU_SW_PATH>/pru_cape directory to arch/arm/boot/dts.
b. In your kernel source tree, open arch/arm/boot/dts/am335x-boneblack.dts for editing.
c. Add the below line to include the PRU Cape DTS file to the bottom of the am335x-boneblack.dts file.
#include "am335x-boneblack-prucape.dtsi"
NOTE

As per steps i followed



Compile the DTS file:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x-boneblack.dtb

while compiling i am getting the error follows :

Hello Ti ,

able to solve gcc problem .

How to solve this

Makefile:953: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop.

From a suggestion from web , installed libelf-dev
