JC 08:22 PM Software Development: RE: Yocto MDK Status: It looks like the vim repo has been moved. googlecode.com is no longer a valid url.

TR 04:02 PM Software Development: RE: Yocto MDK Status: Hi, thanks... suspected that was the case but didn't know where the setting was at. It successfully fetched and is moving on now. Tom Riddle
JC 03:33 PM Software Development: RE: Yocto MDK Status: Thanks for the extra info. wanda.syr.criticallink.com is an internal server, CL_SOURCE_GIT_HOST should point to support.criticallink.com instead. Sorry about that. Jonathan Cormier

TR 09:24 PM Software Development: RE: Yocto MDK Status: Ok, Will try again... hope I can get an answer to the network question... it appears to fail at trying to fetch the following

JC 07:07 PM Software Development: RE: Change data between ARM & DSP cores, undefined behaviour: > They often fail. How to fix it?
Could you clarify what you mean about it failing often? Error messages? What does failure mean? Jonathan Cormier
YY 04:33 PM Software Development: Change data between ARM & DSP cores, undefined behaviour: Hello!
I have MityDSP OMAPL-138F, version linux kernel - 3.2, version dsplink 1.65 (from MDK-2012-03-2012), pc Ubuntu-14.04.05 LTS. ARM & DSP clock freq - 300MHz.
I want to establish a continuous exchange of data between two cores ... Yan Yandoff

AK 08:00 PM Software Development: RE: Yocto MDK Status: The yocto-archive contains all of the necessary files to build the MDK (with the exception of the missing file).
I'm working on adding the @.templateconf@ to the archive for future releases. In the mean time, the contents of the file ... Aidan Klein
TR 02:52 AM Software Development: RE: Yocto MDK Status: Thanks, Aidan. that's helpful. I still had a number of errors, but they may be related to other items here that are not setup properly.
So I'd like to ask a few general setup questions, following the general yocto install instruction... Tom Riddle
TR 05:21 PM Software Development: RE: Building DspHelloWorld MDK 2018: Greg, thanks... So the other option (assuming untested) would be to rebuild DSPlink libs with the XDC Tools version on the CCS v7.3? regs, Tom Tom Riddle
GG 03:17 PM Software Development: RE: Building DspHelloWorld MDK 2018: Hi Tom,
I believe the DSP MDK core library you are linking against was built with Code Composer 6.1. I would recommend using CCS v6.1 to build the DSP Hello World application.
Thanks,
\Greg Gregory Gluszek
TR 02:59 AM Software Development: Building DspHelloWorld MDK 2018: Hi,
I'm setting up a native Ubuntu 16.04 hosted machine for the MDK 2018. CCS v7.3 is installed with the recommended tools and have followed these instructions.

AK 01:07 PM Software Development: RE: Yocto MDK Status: Hi Tom,
From your error message it looks like @CL_SOURCE_GIT_HOST@ and @CL_SOURCE_GIT_PATH@ aren't defined. These variables are defined in Critical Link's Yocto distro, @cl-systemd@.
Since you're building for the MityDSP-L138 you s... Aidan Klein
TR 02:18 AM Software Development: RE: Yocto MDK Status: I have successfully built Yocto core, however when I try to build meta-criticallink I get the following error. Any help would be appreciated.

TR 01:20 AM Software Development: RE: Yocto MDK Status: Following up here... I basically had to update the CC assignment in the Makefile so it could find --sysroot, now it builds correctly. Are these Makefile mods expected or have I missed an MDK setup step somewhere? Please advise, thanks Tom Riddle

TR 05:34 PM Software Development: RE: Yocto MDK Status: Hi,
I pulled over my kernel sources and it builds. Next I am attempting to build some of the 2018 MDK examples. Running into things like ${MDK} was not set, path issues, etc. So beyond installing the MDK and sourcing this file (below)... Tom Riddle
GG 02:54 PM Software Development: RE: Yocto MDK Status: Hi Tom,
The 3.2 branch you are following is the one to track for our latest updates for the L138 platform.
Thanks,

BD 01:54 PM Software Development: RE: Yocto MDK Status: Hi Tom,
We've released some Yocto-based MDKs under the "Files":https://support.criticallink.com/redmine/projects/arm9-platforms/files tab. The latest is 2018.04. We don't have full documentation for creating your own Yocto-based MDK ... Bob Duke
TR 12:18 AM Software Development: Yocto MDK Status: Ok, looks like it may be the appropriate time for us here to cut over to the Yocto MDK. We've been on the MDK_2014-01-13 but the filesystem limitations are starting to hold us back. We've done a significant amount of kernel work integrat... Tom Riddle
