upgrading/building epiphany

[rheiland]

I'd like to upgrade my epiphany sdk and want to make sure I'm doing things correctly. Previously, I had installed:
in /opt/adapteva, /esdk symlinked to /esdk.5.13.09.10

I now have, in /opt/adapteva: /sdk symlinked to /epiphany-sdk-esdk-2015.1

and am proceeding with:
linaro@linaro-nano:/opt/adapteva/sdk$ sudo ./build-epiphany-sdk.sh
********************************************
************ Epiphany SDK Build ************
********************************************

Environment settings:

EPIPHANY_BUILD_HOME=/opt/adapteva
EPIPHANY_HOME=/opt/adapteva/esdk.RevUndefined
ESDK=/opt/adapteva/esdk.RevUndefined

Build settings:

Target architecture: armv7l
Build version: RevUndefined
Build from branch or tag: master

Logging to /opt/adapteva/logs/2015.1/clone-2015-03-29-1112.log

Is this correct, or should I be running some of the other .sh scripts first? Thanks.

I'm definitely confused. The above continues with:

Cloning binutils...
Cloning gdb...
Cloning newlib...
Cloning cgen...
Cloning gdb-multicore-sim...
ERROR: Unable to clone gdb-multicore-sim
ERROR: Failed to download components

and fills my disk, leaving me with:

Help?

Continuing this self-conversation... I've now downloaded just the binary distro(?):
-rw-r--r-- 1 linaro linaro 104926369 Mar 29 13:16 esdk.2015.1_linux_armv7l.tar.gz

and put it in /opt/adapteva, resulting in:
linaro@linaro-nano:/opt/adapteva/esdk$ e-gcc --version
e-gcc (Epiphany toolchain 2015.1) 4.8.2 20130729 (prerelease)

I'm still not entirely certain if this is the way to go. What I want to do next is build

If you just want to upgrade the SDK, the simplest way is to write a new image to the SD card, since the new SDK (2015.1) requires a different kernel than the old SDK (5.13).

[rheiland]

In that case, I'm confused. You're saying I can't use the new (2015) ESDK on my original OS?

From here: http://www.parallella.org/create-sdcard/ ("With Display"), I read:

The following distributions enable the HDMI display on the Parallella board and can be used with the Desktop, Embedded, and Kickstarter versions. Due to challenges with the FPGA HDMI integration, we currently do not have the latest ESDK and power saving features completed and the version below is an older one from June 2014. Software developers doing advanced work are strongly encouraged to use the more up to date headless distribution.

So I'm confused.

[rheiland]

This is what I'm getting when I run a test. Is this due to my updating to the esdk.2015.1 and not changing my kernel? I'm still confused about the headless vs. with-display notice, as I stated above.

They have to go in lockstep. If you are upgrading to the 2015.1 ESDK I REALLY recommend taking the whole microserver kernel as is from the site.

I'm happy to do whatever I need to. I'm just confused on exactly what that is As I mentioned above, when I go to the download site (https://www.parallella.org/create-sdcard/), I find that the distro for a Parallella "With Display" (what I have/want) is actually not up-to-date.

To complicate matters (or not), I'm also ordered a larger (blank) uSD card and will want to burn/use it.

sorry to be dense, but I appreciate the support, Randy

Thanks. I guess I was just in denial - that I couldn't have my cake and eat it too. I definitely want to use the board to do some data visualization, so I need a distro with a "head". But I also want to get the latest goodies with the ESDK. Guess I'll wait to hear what, if anything, the community says about future plans.
