- Hi Christian,
We do not currently distribute the vhdl for the MDK cores that are missing from that project. We do, however, distribute the netlists, which will allow you to build that project. Include the netlists from MDK\fpga\cores\... - MF 11:05 AM Software Development: RE: TFTP (or FTP) Server

We are developing an embedded product. Our application code will run from startup. It will create files. We are also developing a companion application on a host PC to communicate with the embedded application.... - MW 10:50 AM Software Development: RE: TFTP (or FTP) Server
- Normally, we use scp to transfer files to a remote server on the ARM.
You can configure ssh keys to allow transfers without having to type a password in, if you need it.
-Mike
- How do you start a tftp (or ftp) server on the ARM? Or how do you transfer files to a remote server programmatically? I need to have the server start up automatically or be started from a function call, not from a shell command line.

- Tim,
Just hit a key and break and load the code manually?
If you want the FPGA to be loaded, then we often make a separate script for loading the fpga, e.g:
setenv progfpga 'sf probe 0;sf read 0xc0700000 0x580000 0x80000;loadfpg... - I am presently storing the firmware in non-volatile memory when I hand it off for testing. The problem is, sometimes I need to just download some code into ram to test. Is there a way to provide an opportunity to break in a bootcmd? H...

I just did you notice to me "Network configuration" article.
It can changed Ethernet config 2 to 3 or 3 to 2 but it can not changed 2 or 3 to 0. is it normal?

The ISE Webpack license should be sufficient for what you are trying to do.
Try opening one of the projects in MDK\examples\industrial_io\fpga\build_* and see what that tells you. You will most likely be asked to mi...

- The PRU drivers are not installed. You'll need to rebuild the kernel. You may need to patch in the PRU drivers as well.

- Do any of the kernels built by critical link have the PRU drivers installed? Or do I have to rebuild a kernel with this driver?
Jeremy - MW 08:14 AM Software Development: RE: AM1808-industrilal I/O performance

The only time I've experienced the board reseting due to an FPGA load is when I was mistakenly loading the wrong file (i.e. I tried to cat the .bit file instead of the .bin...). If you take the file you sent me and switch ... - MC 05:25 AM FPGA Development: RE: FPGA GPIO: toggle problem

The reason that you're not seeing the echo'ed value of the GPIO change is due to the way the core is connected. In order to solve this you will need to connect the o_io outputs of the GPIO core back to i_io. This was most ... - MC 09:53 AM FPGA Development: RE: FPGA GPIO: toggle problem

I think the reason you're getting a compiler error is because you're only including a single file from the DSPLink code. Take a look at the Makefile used to create the libdsp libraries (MDK/sw/ARM/linux/libdsp/Makefile) for ...

On the Non-FPGA modules, all 4 of these signals have a 1K Ohm series resistor between the on-board nets and the edge connector. This effectively makes putting a non FPGA module into a board like the Industrial I/O kit OK if... - CO 07:49 AM PCB Development: RE: Used EMIFA-Signals/Pins

You can store the DSP image in flash. I am assuming you are running a DSP-only setup (i.e. no linux system running).
