Hi... never mind, need to install the pulseaudio-server. looks good now, thanks. Tom Tom Riddle

TR 09:58 PM Software Development: RE: creating a new rootfilesystem

Hi,
It's the opkg update that I needed to execute. Ok, so now there are quite a few pulseaudio pkgs that are listed, which is good. Also the commands you listed, their output matches what you have. Now I would expect to see the pulsea... Tom Riddle

TR 09:19 PM Software Development: RE: creating a new rootfilesystem

Hi Jonathan,
Hmmm a check here doesn't list pulseaudio. I'm pretty sure that I flashed on this board the mity-omap-full.jffs2 dated 2014-01-13. It lists the fpgautil "trunk+svnr2992-r7" and fpga-driver-modules "trunk+svnr2992-r51". ... Tom Riddle

Note this is for the 2014 MDK filesystem. Jonathan Cormier

It does appear that pulseaudio is available in the opkg package list so you could try installing it using @opkg install@. Hope this helps. Jonathan Cormier

TR 03:43 PM Software Development: RE: creating a new rootfilesystem

Hi Greg,
Thanks. Our immediate task is to add pulseaudio to our MityDSP system, we will be integrating some external codecs shortly. Since pulseaudio is not a pkg that came with the mityimap-full, we need to add it. I do have some yoc... Tom Riddle

Hi Tom,
The quickest and easiest path to customizing a root file system is to start from the file system images included in the MDK under the "fs" directory. The mityomap-base file system is a minimal file system image that you can b... Gregory Gluszek

VV 10:40 PM Software Development: MityDSP L138 DSP Timer

Hi,
I am trying to utilize the Timer peripherals from the DSP side via Syslink, and I have a couple of questions/issues, causing my timers to not run.
What is the clock source for the timers? From the data sheets it says when inte... Vibhakar Vemulapati

Thanks, Mike,
That clarified things.
Regarding my earlier question, "this forum thread":https://e2e.ti.com/support/embedded/tirtos/f/355/t/440203 has the answer, in case someone else needs it.

MW 12:18 PM Software Development: RE: SysLink Configuration

We added minimal support for Starterware for a couple of specific customers that insisted on using it. In those cases, they were not really running multicore. They wanted to either run bare-metal ARM or bare-metal DSP code (not both). ... Michael Williamson

OÇ 04:59 AM Software Development: RE: SysLink Configuration

Hi, Jonathan,
I understand that you do not support SysLink, and using your MDK for ARM-DSP communication is very easy for me, too, given the complexity of SysLink examples and the E2E forum's reluctance to respond to my questions.

JC 07:45 PM Software Development: RE: SysLink Configuration

Hi Okan,
We currently do not support SysLink in the capacity needed to answer your most recent questions. We recommend pursuing your project using our MDK (which utilizes DSPLink instead of SysLink), as we are more able to provide sup... Jonathan Cormier

Hi,
Since I managed to run the example executables in MityDsp last week, I've been trying to modify the codes and understand how it works, but I couldn't even compile any of them yet.

Hi,
I was just about to build a new kernel to set @earlyprintk@, then I realized my @bootargs@ were missing @0x@ prefixes. I fixed it and the kernel now boots. _(Oddly, I never used @0x@ in my other U-Boot commands and I never ran int... Okan Çalış

Hi,
I'm working on a MityDsp-L138F SoM, with the ARM running Linux. So far, I've managed to make the ARM and DSP cores communicate through Critical Link's wrapper functions for DspLink. But my problem is that DspLink does not support ... Okan Çalış
