I'm having some sporadic problems with the device driver I made for our pci-e dev... Alexander Block

09:05 AM FPGA Development: RE: FPGA DDR3 on 5CSX-H6-42A-RC-X (DDR): Hi Nigel,
I don't believe there is a way to do it directly in QSYS. You may be able to patch your generated outpu... Adam Dziedzic
07:59 AM FPGA Development: RE: FPGA DDR3 on 5CSX-H6-42A-RC-X (DDR): Hi Adam,
Thanks for the insights.
Do you know how to persuade qsys to run the DDR at a slower speed? In normal ... Nigel Doe

04:19 PM FPGA Development: RE: FPGA DDR3 on 5CSX-H6-42A-RC-X (DDR): Hi Nigel,
You are correct, the C8ES devices do not meet timing with the FPGA DDR according to Quartus. The ES sil... Adam Dziedzic
01:27 PM FPGA Development: FPGA DDR3 on 5CSX-H6-42A-RC-X (DDR): Although your reference design using FPGA DDR compiles as supplied, when I select the correct device (5CSXFC6C6U23C8E... Nigel Doe

04:31 PM Software Development: Miscellaneous questions: Hi,
I'm using the pre-dev MitySOM eval board and I'm trying to rebuild a complete working environment with the cu... Pierre-Yves BRETECHER

09:58 AM Software Development: Standard USB peripheral connection on MitySOM eval Board: Hi,
I originally wanted to connect to the board either usb storage peripherals or webcams-like peripherals. I bou... Pierre-Yves BRETECHER

05:08 PM Software Development: RE: Pre production (-X) modules with newer sd image: That update to the conf/local.conf should fix the uImage issue. As for the building of the DTB through yocto, we push... Daniel Vincelette
03:42 PM Software Development: RE: Pre production (-X) modules with newer sd image: Thanks a lot for the feedback.
I have noticed that the Yocto wiki has just been updated concerning the uimage format... Pierre-Yves BRETECHER
09:13 AM Software Development: RE: Pre production (-X) modules with newer sd image: I am currently working through the kit and having a similar experience. The following seems to work for me in regard ... Nigel Doe

06:28 PM Software Development: RE: Pre production (-X) modules with newer sd image: Well, the orange LED switches OFF because with this new version of the SD card, the FPGA is loaded with a firmware at... Pierre-Yves BRETECHER

09:34 AM Software Development: RE: Building u-Boot and Preloader: I believe that the files in question need to be copied from software/spl_bsp/generated into u-boot-socfpga/board/cl/m... Nigel Doe

02:23 PM Software Development: RE: Breaking changes on early MityARM: Should have spotted that note but somehow managed to miss it!
Thanks,
Nigel. Nigel Doe
02:00 PM Software Development: RE: Breaking changes on early MityARM: Hello Nigel,
Sorry about that. The description of the hardware changes for the Dev Kit baseboard are here:
htt... Michael Williamson
01:49 PM Software Development: Breaking changes on early MityARM: I have an early MityARM module and dev kit. On trying to implement the latest software versions I found that the Ethe... Nigel Doe
08:42 AM Software Development: Building u-Boot and Preloader: I am just revisiting the development kit after working on other projects and I am trying to locate the copy_files.sh ... Nigel Doe

12:17 PM Software Development: Pre production (-X) modules with newer sd image: Hi,
I'am just starting to discover the eval kit. The one I ordered from Mouser was a pre-prod (- X) version. I und... Pierre-Yves BRETECHER

07:22 AM Software Development: Sample c program to read/write Cyclone V FPGA internal memory through hps2fpga bridge: Hi,
Do you have sample c/c++ program to read/write a memory inside Cyclone V FPGA through hps2fpga bridge interfac... Bill Lee

05:14 PM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: Hi Bill,
Sorry for the confusion. The latest image updated the Baud Rate to 115.2kbps to be consistent with the r... Adam Dziedzic
05:05 PM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: Hi,
I downloaded the sd_image_mitysom_5csx_rev1B.zip, and extracted out the .bin file. Then I typed "sudo dd if=sd... Bill Lee

09:27 PM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: Information on how to make an SD card based upon the current Development Kit SD card image (Rev 1B) can be found on t... Alexander Block
06:17 PM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: Mike,
I think you meant "memtool -32 0xFFD0501C=0x06" for brgmodrst register. The reset value of the register some... Bill Lee
08:52 AM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: For reference on the reset register:
http://www.altera.com/literature/hb/cyclone-v/hps.html#reg_default_component/... Michael Williamson
08:51 AM FPGA Development: RE: How to access FPGA internal memory through AXI slave interface protocol: Hi Bill,
It looks like you are using version 3.8 of the kernel. Version 3.8 does not have the FPGA bridge drivers... Michael Williamson
