Linux/BEAGLEBOARD-X15: BEAGLEBOARD-X15/Linux_RT

VLeshka VV

Tool/software: Linux

Beaglebone X15
SDK 5.01.00.11
Linux RT Arago.

When I compile the program in arago, there are an error message:
make: /usr/bin/clpru: Command not found

As I understood, I have to copy the clpru from sdk. But there are only 1 file at x86 directory:
ti-processor-sdk-linux-rt-am57xx-evm-05.01.00.11/linux-devkit/sysroots/x86_64-arago-linux/usr/share/ti/cgt-pru/bin/clpru

I have copy this file to /usr/bin/, and then the compiler executes an error message:
/usr/bin/clpru: /usr/bin/clpru: cannot execute binary file

As I understood, I have to copy the clpru for arm.
Help.

Hello,

Please provide more information about your question. What is "the program"? (for example, are you asking about how to compile PRU firmware and then load the firmware into the PRU in Linux? Are you asking about something else?)

Regards,
Nick

If you need: the program is “Hello, world!” (remoteproc version) http://theduchy.ualr.edu/?p=996

I need to compile this program.

Hello,

TI does not support the Debian filesystem, and we do not support 3rd party code. However, TI does provide example PRU programs that can be compiled within the SDK at example-applications/pru-icss-x.x.x/examples/am572x/ . We include Makefiles that you can use as a template.

Please see documentation for compiling and testing the PRU example code in the RPMsg Quick Start Guide. Note that the document was written for AM335x, so there will be small changes. In particular, the PRU cores are probably not assigned to remoteproc0 and remoteproc1 for AM57xx. Use a command like cat /sys/kernel/debug/remoteproc/remoteproc*/name to see which cores are associated with which remoteproc numbers.

General PRU documentation may be found at the PRU-ICSS Wiki page.

Regards,

Nick

I'm not asking for the "3rd party code", I'm asking for the file, that including in x86 but not in Arago.

Please use the documentation I provided to get a known working case. You can then work backwards from the working case to discover what you are missing. At the moment, you have not given me enough debug information to provide any additional assistance.

Are you suggesting that I should not compile the "Hello world"?

0 Nick Saulnier over 7 years ago in reply to VLeshka VV

TI__Guru** 108900 points

TI has sample PRU code, sample makefiles, and tutorials that I have verified as working. TI cannot test and verify random PRU code, makefiles, and tutorials from other parts of the internet.

I am suggesting that you can use the resources that TI has validated in order to learn about the PRU. You can then use the TI resources to figure out how to get your third party "Hello World" example to compile.

Nick

Ok, thanks.
Frankly, I was looking for a simple example (for A15) of data exchange between A15 and M4 (your variants are not suitable for this).
If you can tell me, I'd appreciate it.

Hello Leshka,

We will get someone familiar with M4 to comment. Please let us know if this is a good summary, or if you want anything changed:

You are no longer asking about compiling code for the PRU core. Now, you are looking for an example that demonstrates data exchange between an A15 core running RT Linux, and an M4 IPU core running RTOS.

Nick

Yes, It is. I think it should not create a separate topic for example of M4.

Hello,

Please take a look at the IPC package. An overview of it can be found here:

Thanks for answer.

I started looking at your examples.

Acording to the http://processors.wiki.ti.com/index.php/IPC_Users_Guide/Examples :

git clone git://git.ti.com/ipc/ipc-metadata.git
git clone git://git.ti.com/ipc/ipc-examples.git

So I got the ipc-examples and ipc-metadata katalogs. I'm more suited to the ipc-examples\src\examples\templates\ex01_hello\ .

Acording to the readme file of ex01_hello, there should be a file (for example) for dsp: dsp1/HelloDsp1.c. but there is no this file.
A need the file for M4, but it is not the same.

Where to get these files?

Hi, VLeshka,

We are revamping the IPC User Guide, so the URL link you provided is not accessible now. I can't see the content of it. Please see the IPC Quick Start Guide on sections of Building IPC Linux examples and Running IPC Linux examples.
software-dl.ti.com/.../Foundational_Components_IPC.html

It seems to me that you try to build IPC example on the EVM. The native build is not supported. Please follow the instruction in the Quick Start Guide to build on Linux Host machine (e.g. a Ubuntu machine). You do need to build on Linux side first (high level "make ti-ipc-linux). To build the example host application, IPC linux library is needed which is not included in the PLSDK.

In the filesystem (tisdk-rootfs-images.tar.xz), there are prebuilt example images in /usr/bin/ipc/examples. The Arago-based-tisdk-image.tar.xz filesystem won't have them if you are using arago filesystem.

About software-dl.ti.com/.../Foundational_Components_IPC.html :

Is it okay that the source code of demo examples are only available for RTOS on Keystone-2 EVMs?

0 Rex Chang over 6 years ago in reply to VLeshka VV

TI__Guru 50170 points

Hi, Vleshka,

No, that is not the case. It only says the out of box demo (running from the GUI interface) is available on KS2 EVM. On AM57xx EVM, the GUI doesn't have the Multi-core Demostrations icon to run it. You can still run it from Kernel console. The M4 demo binaries are located in /lib/firmware/ipc/ti_platforms_evmDRA7XX_ipuX folders. The host binary is /usr/bin/MessageQBench.

Or you can run the prebuilt examples (such as ex02_messageq) in the filesystem as I indicated in my previous post.

There are includes (for example, in examples\AM572X_bios_elf\ex02_messageq\ and examples\AM572X_bios_elf\ex11_ping\):

/* xdctools header files */
#include <xdc/std.h>
#include <xdc/runtime/Diags.h>
#include <xdc/runtime/Error.h>
#include <xdc/runtime/Log.h>
#include <xdc/runtime/System.h>

But there are no any tree nodes like a xdc/*.h. Not in the rootfs or in the sdk 5.01.
Where should I get them?

Hi, VLeshka,

For supported IPC Linux examples, please take a look in <RTOS_PDK>/ipc_x_xx_xx_xx/examples/DRA7xx_linux_elf directory. Only those examples in the directory are supported for that platform. Since you are running Linux on ARM, you should look under DRA7XX_linux_elf, not DRA7XX_bios_elf directory. The bios directory is for all RTOS environment. That is RTOS running on both ARM and DSP.

For IPC build, please refer to IPC Quick Start Guide "Build IPC Linux examples" which uses high level build to rebuilt the examples.
software-dl.ti.com/.../Foundational_Components_IPC.html

I went back to your original post. If your question is regarding PRU, then all the posts don't apply. I'll have someone else to help you.
Please confirm.

Hi, Vleshka,

You haven't confirmed if the issue is PRU related. Please confirm either way. If your issue is resolved, please click "Resolved".
