- GG 10:36 PM Software Development: RE: creating a new rootfilesystem
- 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... - We are using an L138 with MDK 2014, using kernel 3.2.0 we have a need to create a rootfilesystem. I found a few links

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...

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.

- 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). ...
- 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.

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... - OÇ 01:34 PM Software Development: RE: SysLink Configuration
- 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.
The TI wiki has a "Creating CCS Project for Sys...

- 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...

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 ...

So I was able to import and rebuild the SigProc lib example in the MDK-2014 /sw/DSP/lib/SigProc using CCS v5 on windows, plan to move that over to CCS in Linux.
Are there any simple examples available or documentation for how ... - MW 01:17 PM Software Development: RE: Setting the ARM as a USB bulk device

I guess the question is if that is acceptable for your ... - JC 01:00 PM Software Development: RE: Setting the ARM as a USB bulk device
- Looking at some of the speed tests we ran with RNDIS, we were seeing about 10Mb/s or ~1.25 MB/s. So you results seem pretty good in comparison.

Awesome thanks for the update. - JL 03:30 PM Software Development: RE: Updating devkit to latest MDK tfpt issue
