DV 07:53 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive
Hi Jared,
I'm in the middle of recreating your test with one of our dev kits. I'll connect up the MOSI to the MISO in the FPGA and run your test app. I'll let you know what I see, should be by end of day. I'll look into the RX issue f...

NS 08:10 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: yocto meta-mitysom-335x no recipes and files.
Hi Bob,
thank you for this explanations and for pushing the daisy branch.
I will wait the release for the layer MitySOM-335x if I can't use succeed to create my own build environment with the layers of the daisy branch.

BD 06:51 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: yocto meta-mitysom-335x no recipes and files.
Hi Niko,
We are in the process of releasing the associated files for our MitySOM-335x Yocto MDK build (we should have everything completed by the end of the month). In the interest of helping you, I have pushed the daisy branch to th...

NS 04:32 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: yocto meta-mitysom-335x no recipes and files.
I have the MitySOM-335x Development Kit and I would like to create a custom linux system.
I search on your website if there is some layers which can be used with yocto and I found the "meta-mitysom-335x" layer (this is the link where I ...

JK 01:47 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive
Hello Mike,
I modified the SPI device tree entry to have an "spi-max-frequency" of 1 MHz (a slow clock speed, as you suggested, to get started).
I kept the FPGA image in which we connected MOSI to MISO (rather than using the "loop ...

Hello Mike,
I just saw this message, and will try it out first thing tomorrow. Unfortunately, a snow storm is preventing me from being in the office to try this out today.
Thanks,

MW 05:20 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive
Here is some example code from the linux kernel documentation area.
BTW: our FPGA driver and the SPI HPS "hardcore" have a built in loopback mode, so you don't need to physically rewire the FPGA at the top level.
Can you run thi...

JK 05:34 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive
Hello Mike,
We've since conducted a loopback test (MOSI connected to MISO within the FPGA) and observed no change in behavior (still an empty receive buffer). The SCLK and CS lines are still behaving as expected as measured by an osci...

JK 08:28 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive
Are you referring to modifying the FPGA such that MOSI is connected to MISO?
If that works, it might indicate that somehow our MISO signal isn't hooked up correctly in the FPGA (which I'd be surprised by due to another test described ...

Have you tried using the Loopback option to see if you can just loop back the command data and if RX is OK?

Hi Jonathan,
I thought so. Ok, I'll try to do somthing with it.
Thank you for help.

Code Composer is very finicky about exact paths for the Platform.tci file. It's possible you went too many, or too few directories in when specify this information under Properties->Build->TCONF->General Options or when creating the DSP/... Jonathan Cormier

Hi Jonathan,
I use CCS v.6.1.0 and MDK of 2014 year.

Hi Artem,
What version of Code composer are you using? Also what MDK version?

MR 10:27 PM MitySOM-5CSX Altera Cyclone V PCB Development: Standoff on Mounting Hole Locations page
I believe there is a small errata on the [[Mounting_Hole_Locations]] page.
At the bottom it states... "Standoff: McMaster Carr PN - 91115A510" ... This is not an actual part number in McMaster.
I think the last two numbers where switch...

Good day,
I'm trying to set up the “DSP Hello World” from the Wiki instructions (https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/DSP_Hello_World). “Compiling for the ARM” was ommited, as the main goal is to run ...
