Alex Thanks... that's helpful. Regs, Tom Tom Riddle
AB 10:11 PM PCB Development: RE: Supplying an external PCB
Tom,
We have used these (https://www.digikey.com/products/en?keywords=87759-5050) on a couple of our expansion boards for the Industrial IO board. Note that they are surface mount headers.
I believe these (https://www.digikey.com/...

TR 08:05 PM PCB Development: RE: Supplying an external PCB
Hi, One additional question. The Industrial I/O dev kit doc mentions the Expansion IO Interface mating connectors is 2x25, 2mm header. Do you have a suggested vendor/part number you've used in the past... something that Digikey/Mouser wo... Tom Riddle

+5V supply Pins 1,2 on J104

Note: 3A at 5V is 15W. There is a 1.1A fuse on the 12V side, which will limit this to 13.2 W. Or 2.64 A @ 5V so 2.5A to be safe...

TR 05:43 PM PCB Development: Supplying an external PCB
Hi, We're going to be running a few development boards off of the MityDSP L138. For one we plan to use the +12VF from J701. The other it would be nice to use either the +3,3 or 5.0v supplies from TPS5430 buck converters directly. Since w... Tom Riddle

JC 02:40 PM Software Development: RE: How to activate splash screen
On the MDK 2014 filesystem, psplash is started first thing during rcS. I don't have my dev kit setup for a display right now so can't test that. Jonathan Cormier
AH 09:00 AM Software Development: How to activate splash screen
Hi everyone,
I found psplash in the root file system and currently able to modify the screen.
However, I can't activate it in the boot process. Can you please provide some hint how to do it?
regards,
Andri Haryono

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...

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". ...

Note this is for the 2014 MDK filesystem. Jonathan Cormier
JC 03:49 PM Software Development: RE: creating a new rootfilesystem
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...

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...

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...

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
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.

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...

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...
