AD 02:57 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: LVDS transceiver for 1000Mb Ethernet MAC & 1000Base-X problem

Hi Charles,
The GXB TX details can be found in Altera's documentation:

MJ 08:52 AM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: Linux application cannot read/write FPGA registers

Hi Greg
Excellent, that has definitely helped as I can now see /dev/0 after the following two commands (with FPGA loaded from uBoot). Mathew Jones

MW 12:43 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem

Hi Mathew,
Very sorry about that. I didn't catch the LX45 version. The LX45 has some pins that are not bonded to the FPGA package causing the limitation on our devkit (originally designed for the LX16).
Are you using a widescree... Michael Williamson

MJ 11:26 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem

From our investigation and suggestions from other wiki/forum pages it is apparent now that it is not possible to output to a DVI monitor from a MityDSP-L138 + Industrial IO development board, with the LX45 FPGA. We have since purchased t... Mathew Jones

GG 11:35 AM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: Linux application cannot read/write FPGA registers

Hi Matthew,
First we need to deal with the issue of /dev/0 not being present. Using /dev/mem is ultimately not what you want to do as you will run into caching issues.
/dev/0 is created after the FPGA is loaded and the device driv... Gregory Gluszek

MJ 11:16 AM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: Linux application cannot read/write FPGA registers

I am trying write a simple C application (for Linux on the MityDSP-L138 ARM) that can access registers within an LX16 FPGA image, which is yet to be implemented but I'd like to get the basics working for now with any of the CriticalLink ... Mathew Jones

CG 11:08 AM MitySOM-5CSX Altera Cyclone V FPGA Development: LVDS transceiver for 1000Mb Ethernet MAC & 1000Base-X problem

Hi,
I have been attempting to use the development kit to setup and implement a system which interfaces to an externally connected SFP module which I have connected via the SPIe connection to the dev board. I instantiated the TSE Ethern... Charles Garcia

Also, please make sure you perform the extraction as the root user: Bob Duke

JC 03:51 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: gcc 4.8 for OMAP-L138

Yes, extract the tar ball onto the root filesystem, but make sure to erase the existing one first. And backup your important files of course.
Please let us know if there are any tools missing from the new filesystem that you used in ... Jonathan Cormier

BA 03:23 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: gcc 4.8 for OMAP-L138

Bob,
Thank you for the response regarding the new gcc cross-compiler for the MityDSP-L138. Now that we're back from the holidays, I was able to successfully cross compile our application on my build machine.
I'm a little unclear, ... Ben Atkinson
