- MW 06:56 AM Software Development: RE: Downloading and Installing the Virtual Machine?
- I think there is a link to the VM appliance, I'll try to get someone to post that for you.
There is a newer image, but it simply has the newer MDK images and toolchains installed as well as support for the MityARM-335X (Cortex-A8 prod... - Hi Folks,
The Wiki says the current version of the VM appliance can be downloaded, but I can't find a download link. Does one exist?
I have the VM from the DVD that came with my board (dated Monday, April 11, 2011 9:10 AM). Is this...

- Hi,
I was able to walk-through the DSP_Hello_World tutorial. The test applications seems to run well until arm application ends. There are assertion messages printed at the end. It happends only when the arm application uses the relea... - CK 07:47 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

Thanks, that did the job.
The bad news is that 3.2.0 does not have KS8995 support. It seems that this only starts in 3.3.0

- I don't think your compiled correctly or uploaded the correct uImage to the machine.
The "Image Name: Linux-2.6.34-rc1-00098-ga450029-" suggests that your are still building off the master branch, and not the mitydsp-linux-v3.2 branch... - CK 04:34 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

I have found a branch 'mitydsp-linux-v3.2', which I assume is the one you referred to, which I am downloading now. I will let you know how I get on with it.

Thank you for your assistance. I would like to look at the version 3.2, so if you could let me know how to access it I would be obliged.
The switch on the dev board will be used initially to allow me to connect to our local ne... - MW 09:50 AM Software Development: RE: KSZ8995MA Ethernet Switch Support
- Hi Charlie,
I guess the first question is, "what do you want to do with the switch?". As I mentioned before, we have successfully implemented the KSZ8995 into at least one design here, and if you have all the ports mentioned above co... - CK 09:22 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

I am the customer who submitted this post. I had a problem with logging on which is why Tom posted this for me. Hopfully, I have now sorted this out.
I am new to Linux, so if the questions sound naive, then that is because I a...

Are you not able to send/receive packets from the OMAP-L138 to the switch?
Typically, these switches power up w... - (posted on behalf of a customer)
Have you, or do you know of anyone who has got a KSZ8995MA Ethernet Switch chip to work with the MityDSP-L138? The chip works fine as a switch but I want to get the Linux to recognise it. I will presum...

- MW 08:40 AM Software Development: RE: Starterware EMIFA to FPGA example code
- Hi Emmet,
The processor will write or read the first (lower address) 16 bits first, followed by the upper 16 bits when configured in little endian mode.
We've been coding this way for a long time (since the TMS320C671x) and I thoug...

Can you tell me which 16-bit value is transferred first?
I need to make VHDL to pass all 32 bits on the same clock edge to other 32-bit IP in my FPGA design.

Did you remember to saveenv? (just checking)
A couple of things:
You might want to avoid using the "bootfpga" environment variable. We've had a couple of customers manage to brick their system by programming v... - TE 02:15 PM FPGA Development: RE: Programming the FPGA

I am calling the following:

The first one seems to be most applicable, since I have the MityARM-1808F with the LX16 FPGA.

Thanks for the detailed answer. We are only using the AM1808 as an embedded video server for the stream coming from the FPGA, so I cannot comment on the AM1808's H.264 decoding capabilities. But we have used the AM1808 to stream...

If you would like to use the full TI DVSDK (including C6EZAccel), you can install it from TI (along with the Code Sourcery tool chain). You can use TI's libraries and filesystems, etc. The only thing you will need to do ... - Dear Sirs,

- MW 10:19 AM Software Development: RE: uPP/DMA registers
- If you are not using the on-Board NAND in your design (e.g., booting to a RAMDISK or off of MMC or something), then the EMIFA would probably work. Though, you may still have to roll up a kernel module/driver to fetch the data (I would r...
- SM 09:52 AM Software Development: RE: uPP/DMA registers
- Hi Mike,
Thanks for the prompt reply. Actually the data stream is from an H.264 encoder in an FPGA, so im not sure if VPIF would be helpful here. Thats why I was looking for a uPP driver. The other option seems to be the EMIFA interfa... - MW 08:18 AM Software Development: RE: uPP/DMA registers
- Hello Shahzad,
Unfortunately, there is still no UPP driver available. Have you looked at pushing the data in using the VPIF? Supposedly, there has been some work done by TI to push a couple of different modes of camera data using th... - SM 04:11 AM Software Development: RE: uPP/DMA registers

I am looking for a uPP driver for linux and I was searching around when I came across this thread. I know im replying to a very old thread, but I noticed that you mentioned that critical link does not have a uPP driver yet. F...

Are you using linux or starterware? On starterware, if you are launching from u-Boot (which configures the EMIFA to have some nominal timings for CS5 space), then all you need to do is perform memory read or writes to 0x66... - Hello,
