Latest Debian image have the kernel and uenv into the filesystem. To build this image I had no modification to make to the uenv and it detected the logi on first boot ! Since the Debian image was based on earlier version of the loyibone code (latest…

It seems that the information read from your cape eeprom is bad (have you tested this board with the default logibone image). Here is a link to a latest Debian image that I tested with the logibone: https://www.dropbox.com/s/4gmcpigtdpap5br/debian_j…

Can you lake sure that the logibone is properly detected (/dev/logibone and /dev/logibone_mem exists ? Can you do a "dmesg" and see the output after trying logi_loader
-
Hi tarik, Did you saiy that you tried the demo with camera disconnected and the led0 would remain on ? The led should be blinking fast only with camera connected. Did you try to run the wishbone demo ? The wishbone demo will help make sure that th…

Hi, sorry for the mistake in the wiki. Every new board need to have its eeprom configured and you may have to re-configure the eeprom as we release new images. Thanks for the feedback, the documentation was updated. Regards, Jonathan Piat

Hi, you are right simulation is an essential tool for the hardware designer. We use test-bench to evaluate our components most of the time (depends on the complexity) and some of the projects comes with a test-bench. Other test-bench (not well main…

Hi, logibone support is integrated into the official kernel : https://github.com/RobertCNelson/linux-dev (branch am33x-v3.8). The linux-dev in fpga-logi-dev is a fork of the official kernel (all modification to date were merged). The spi loader i…
-
Hi, Latest logibone kernel integration supports spi out of the box. The device tree file was modified to use the spi in pin muxing and the logo loader tool was updated to use spi. It means that the FPGA loading can now be performed with a user spac…

Hi, (this conversation continued on support@valentfx.com) today is built a new debian image (Jessie), did the test of running the img_proc application and it did not work on first try ... but worked on the second. If you experience the same proble…

Hi, what do you find missing for the camera-demo project for logibone ? The project is in https://github.com/fpga-logi/logi-projects/tree/master/logi-camera-demo/hw/logibone/ise and depends on the hard-cv library : https://github.com/jpiat/hard-c…
-
Hi, LED1 in this application is connected to the camera vertical synchronization signal, so as @mjones stated it should blink at 30Hz. LED0 is connected to the reset signal so it should be off all the time. No VSYNC from the camera can mean that yo…
-
Hi, for some of the projects there is more than one ucf files. These ucf files are prefixed with the board name (logibone/logipi) and suffixed with the board revision (ra1, ra2, ra3, r1). For the ra1 and ra2 (older board revisions), the clock pin w…
-
Hi Caludiug, if you want to play with the GPMC configuration, you'll have to compile your own kernel as flatten device-tree will require to embed device tree configuration into your kernel (at least if you want the device tree configuration to be l…
-
We don't have such module. Do you mean you don't need an addressing part for your implementation ? You can have a look at the hard-cv repository : https://github.com/jpiat/hard-cv the spi2ad is in "hw/rtl/interface". Sorry about the verilog impl…
-
Hi, The spi2ad was the old module before we switched to wishbone. You now can find the spi2wishbone in RTL/wishbone. Some of the test bench might be outdated sorry about that. Regards, Jonathan piat

Hi, thanks for the hint. I never used std_logic_arith because i knew it was deprecated but never knew that they were also deprecated. Can you fork our repository do the modification and then apply for a pull request so every user can benefit from y…

Hi, when you go on http://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.html you should download the full installer for your OS in the middle of the page. The license setup should be proposed after installing…
-
Hi Ron, there is a wishbone_sared_mem component in the logi-hard repository that does just that. This component can be read/write from the wishbone bus but also have a read/write interface for the general logic. For the software side you can acces…
-
Hi, maybe the wiki is not clear on this point, but the pre-configured image is already fully configured and tested so all the steps described in the wiki does not apply. These steps are to be completed if you start from a stock raspbian image. I w…
-
In fact this setp was already in the wiki Logi-Bone Quick Start guide, "First boot of the logi-image". Another solution could be that we provide a linux image setup to flash the eeprom automatically on first boot.
-
You are right we need to add this setp to the guide. At first we thought of integrating this step at the manufacturing stage so a flashed board would arrive at your door step, but we completed the (true) linux integration too late. We will soon have…

Hi, did yuo flash your logibone cape ? There is a deploy folder in the ubuntu home directory and a init_eeprom.sh script. Run this script as sudo to configure your cape eeprom then reboot. regards, Jonathan Piat
-
Hi, this is what you can expect from the code on the github. One led blinks while other one execute the well-known heart-beat pattern. I'll modify this to have the code consistent with the wiki. Regards, Jonathan Piat
-
Hi claudius, we haven't written the flash loader code for now because we found the loading from the host system very convenient. There is two ways, the flash could be loaded from the beagle : 1) Load a flash loading design in the FPGA and then use …
-
Thanks for the feedback. There is indeed a small mistake in the script of the wiki. You'll need to replace : sys.path.append("/home/pi/logi-tools/python/logi_hal") with sys.path.append("/home/pi/logi-tools/python/") I'll fix the wiki. Regard…
-
Hi, the LX9 could theoretically run jpeg compression (but i never tried). Another option could be to partition the video encoding you want to use by offloading some of the encoding tasks to the FPGA. FPGA can be very good at pixel level operations…
-
Hi, the logipi only has a 16Mbit serial flash. This flash can be used to retain the FPGA configuration so that is loaded on power-up instead of being loaded from the Raspberry-Pi. This flash could additionally be used to store data for your archite…

Hi Jim, i run the Xilinx tools on a Ubuntu (12.04) 64bit so i should be able to help. To get ISE running on your Linux based computer, you need to go to : http://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.…
