02:47 AM Software Development: RE: FPGA_GPIO input polling: Hi Mike
Thanks for your answer.
It would be nice to have the FPGA_gpio interrupt (poll) function working, so I'... Brian Rasmussen

05:55 PM Software Development: RE: Problem with FPGA reload: I think this is a problem with the unload of the fpga_gpio driver. I am not sure if it is unregistering with the gpi... Michael Williamson
04:42 PM Software Development: RE: FPGA_GPIO input polling: Hi Brian,
The gpiolib framework is a little more rigid than I had hoped, and updating the fpga_gpio driver to incl... Michael Williamson

12:04 PM Software Development: RE: FPGA_GPIO input polling: Hi Brian,
The current fpga-gpio arm linux driver does not support interrupt notification at the moment. However, ... Michael Williamson
11:13 AM Software Development: FPGA_GPIO input polling: Hi
I'm trying to get my user application notified when a FPGA GPIO input pin goes high.
I have created a FPGA ... Brian Rasmussen

11:09 AM Software Development: Problem with FPGA reload: Hi
I have a minor problem when I reload the FPGA image after the OMAP has booted into Linux. I'm not able to expor... Brian Rasmussen

10:16 PM Software Development: RE: Where can I get the files listed on the DSPLink Hello World wiki?: I'm also looking for the files, would you plese email me too. zhiming wu

10:40 AM Software Development: RE: Include Path / Where is the correct source files?: Hi Mike
I have now found out how to map kernel space into user space, though I don't have an example working yet.
... Brian Rasmussen
04:29 AM Software Development: RE: Include Path / Where is the correct source files?: Hi Mike,
I will search the net for a mmap example. Regarding the NAND device it is already mounted.
Thanks for ... Brian Rasmussen

12:51 PM Software Development: RE: Include Path / Where is the correct source files?: Brian,
Good to hear the gpio is working for you.
You are trying to memory map FPGA space into userspace. The w... Michael Williamson
10:43 AM Software Development: RE: Include Path / Where is the correct source files?: Hi Mike
I now have the FPGA communication up and running, and I can toggle an FPGA output pin from the command lin... Brian Rasmussen

02:17 PM Software Development: RE: How Do I Get SD Memory Working for Critical Link Carrier Board From Linux: David
the mount is done by udev. The scripts for udev are in /etc/udev/scripts
the file mount.sh is the one that mo... Tim Iskander

TI has published performance numbers for their basic kernel (which our port essentially sits on top of) ... Michael Williamson
10:05 AM Software Development: RE: How Do I Get SD Memory Working for Critical Link Carrier Board From Linux: Tom,
Thanks for your response. We would desire 4MB/s. Do you know how close to that number we could achieve?
... david kasper
09:19 AM Software Development: RE: How Do I Get SD Memory Working for Critical Link Carrier Board From Linux: Hi David,
What throughput do you need or expect to get? I don't think the SD card is ever going to be as fast as ... Thomas Catalino

09:39 PM Software Development: RE: How Do I Get SD Memory Working for Critical Link Carrier Board From Linux: Mike,
The micro SD card is functioning with a FAT filesystem in our system. However, the write bandwith is slower... david kasper
