Hi Caio,

Could you see the following sites:

Hi Caio,

In addition to Ivan suggestions, I would like to add one more link which is helpful for PRUSS bring up.

http://processors.wiki.ti.com/index.php/Soft-UART_Implementation_on_AM335X_PRU_-_Software_Users_Guide

Hello,

I  found in this link: http://mythopoeic.org/bbb-pru-minimal/

This document: http://mythopoeic.org/BBB-PRU/03-AM335x_PRU_Linux_Application_Loader-ug.pdf

And I'm trying to follow the steps in the "Installing PRU application Loader"

I downloaded and installed the SDK normally.

But when it say to add a line in the Makefile: 

"$(MAKE) -C $(LINUXKERNEL_INSTALL_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE)menuconfig"

and try to use the "make" command I receive that one file wasn't found:

"/opt/ti-sdk-am335x-evm-07.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf-menuconfiggcc"

What can I do to fix that?

Thanks!

Try

"$(MAKE) menuconfig -C $(LINUXKERNEL_INSTALL_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE)"

Or

"$(MAKE) menuconfig -C $(LINUXKERNEL_INSTALL_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE)  menuconfig"

I had to install the "ncurses" using: "sudo apt-get install libncurses5-dev"

Then I used in the Makefile:

"$(MAKE) menuconfig -C $(LINUXKERNEL_INSTALL_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE)  menuconfig" 

Then the Linux Kernel Configuration opened and I tried to find the "Texas Instruments PRUSS driver" but it wasn't there.

Do you know what i missed?

Thanks for your help!

Hi Caio,

What is your SDK version ?

SDK 7.0 ?

I took it in this site:

http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html

Then I downloaded the first one: ti-sdk-am335x-evm-07.00.00.00-Linux-x86-Install.bin

That's the last version, the SDK 7.0

Hi Caio,

I've also checked the SDK 7.0 but not able to find.

http://processors.wiki.ti.com/index.php/Soft-UART_Implementation_on_AM335X_PRU_-_Software_Users_Guide#Location_of_the_Source_Code

I think, SDK 7.0 not having PRUSS driver but linux 3.2 does.

https://www.gitorious.org/pru/am335x-pru-linux-drivers/source/41117e14142bd810a78f501f809dcb54b25fb2ce:

In SDK 7.0,

The "DM850" architecture needs to be selected in order to enable "PRUSS" driver support.

http://processors.wiki.ti.com/index.php/PRU_Linux_Application_Loader

The "Texas Instruments PRUSS driver" don't apper for me in this option. I do have only:

--- Userspace I/O drivers │ │

│ │ < > Userspace I/O platform driver with generic IRQ handling (NE│ │
│ │ < > Userspace platform driver with generic irq and dynamic memo│ │

│ │ < > Hilscher NetX Card driver (NEW) │ │
│ │ < > Humusoft MF624 DAQ PCI card driver (NEW)

But I think I know why, i didn't the step of "PSP release 04.06.00.03" on the first step. So now I downloaded using:

"git clone git://arago-project.org/git/projects/linux-am33x.git"

but I couldn't find any installing guide, do you have one?

Thanks for your help !

Hi Caio,

What about the kernel version of this one ?

May be it could be based on board file (not dts) support so you can configure the kenel with "arch/arm/configs/<am335x def config> "

The kernel version of my Ubuntu is "3.13.0-40-generic" 

Where I can find this file? And how could I use it to install the PSP 04.06.00.03 in my PC Linux?

I was trying other ways, so I find this guide: http://www.elecinfo.com/upload/community/2014/01/05/1388917696-24786.pdf

In this PDF they say that my folder's installation has a "setup.sh" which would configure everything, but when I execute this script:

"Verifying Linux host distribution

Unsupported host machine, only Ubuntu 10.04 LTS and Ubuntu 12.04 LTS are supported"

So I won't be able to install this SDK in my Linux PC? Or the script only work with these distributions but if I would do every step by hand I would be able to install this SDK?

Thanks for your help !
