Build confusion. e-loader lib confusion

[AndyC]

Hi Guys,

I have built the latest 5.13.09.10 sdk on a linux box for cross compiling.

The installed version on the parallella is also 5.13.09.10.

Now the linux box sdk used the e-loader.lib for building, while the contents of this lib seem to be in e-hal on the parallella board.

So when I cross compile and run on the parallella the e-loader.so is missing.

why are the two different? Do I have to build the sdk on the parallella board as well to get it the same?

thanks for any help

Andy

Ok rebuilt esdk on the Paralella and switched esdks to new one with the symbolic link in /opt/adapteva.

Now I'm getting:

linaro-nano:/opt/adapteva> e-reset
e-reset.e: ee_write_esys(): /dev/epiphany file open failure.
e-reset.e: e_open(): /dev/epiphany file open failure.
e-reset.e: e_reset_system(): e_open() failure.


I'm really beginning to loose the will to live with this board!

Is the only support route through this forum?

Andy,

If you are building the SDK from git you will need to use a Linux kernel which contains the Epiphany device driver. You can build a kernel which includes the Epiphany driver from the bcxcube_epiphany_driver branch of the parallella-linux-adi repository (https://github.com/parallella/parallella-linux-adi.git). Also, you'll need to either manually change the permissions on the /dev/epiphany device node or create a file named /etc/udev/rules.d/90-epiphany-device.rules which contains the following:

[bcxcube@parallella-bsc ~]$ cat /etc/udev/rules.d/90-epiphany-device.rules
################################################
##/etc/udev/rules.d/90-epiphany-device.rules

# Set appropriate permissions on the epiphany device node
KERNEL=="epiphany", MODE="0666"

Using a udev rule to set the device node permissions is recommended so that the permissions will be set automatically when the parallella boots.

Hi Ben,

Thanks for the info.

I had just about given up all hope, I will build the kernel and give that a try.

Many thanks

Hi Ben,

I just want to say thanks.

I built the bcxcube_epiphany_driver branch and installed it.

Now I can cross compile correctly from my linux box, very happy camper now

Cheers

Andy
