I have just test and re-confirmed that I get this behavior on 2 BBB's. Each BBB has a different angstrom versions installed on emmc. #1 emmc: Angstrom v2012.12 sd: Ubuntu 13.10 \n \l (latest logi image) #2 emmc: Debian GNU/Linux 7 \n \l …

@jpiat, Stangly my bone/logi automatically boot from the SD card without having to erase the eMMC. When I detach the sd card it will boot from eMMC. It seems that there is somehow a priority to boot from the SD card in my case. I am not sure ho…

@zorgee I would recommend cloning the logi-apps and running the wishbone demo. It has everything configured to work out of the box. http://valentfx.com/wiki/index.php?title=LOGI_-_Apps_-_Project git clone -b logibone https://github.com/f…

@darkhelmet Glad to hear it worked well for you. Just note that the pins connected to the Flash/FPGA are shared with the BBB. So, in order for the FPGA to self boot, these pins tristate on the bone will need to be set to the appropriate state. I…

@jpiat Do you have links to available overlays for these 2 main configurations?
-
@darkhelmet Here are some low cost JTAG adapters from digilent inc. I think that there are some other alternative low cost options available on ebay and elsewhere as well. @jpiat may be able to comment further on any other approaches for l…
-
@darkhelmet Good questions. logi loader is what we recommend using as it is very dynamic in being able to load/reload files from bone user space. In order to automate FPGA configuration you can setup a bone boot script that automatically calls …

Hi Tarik, I believe that the lcd module eeprom is loading it's own overlay, which is likely conflicting with the logi-bone overlay which it is trying to use. I think that the logi-bone has priority for it's eeprom overlay as it is assigned addres…
-
Sure thing. Glad it helped. Just be careful with the "rm" and other such commands now that you are super! Can cause some damage .
-
How about as super user (root access)? "sudo su" from ubuntu user account? Exit super user (root access) mode using "exit"?
-
And here is the LOGI-Bone pin usage pinout for reference. Taken form the LOGI Bone manual.
-
Here are some possibly conflicting pins. The pinout shows the 4D systems pinout. I have circled green with what should be ok and red where there may some conflicts that will need to be looked into.
-
I should also note that my guess would be that it is an overlay issue rather than fpga IO state issue. The FPGA pins are all in HiZ until it is configured, which would should allow the logi-bone to be passive until it is configured with the corresp…
-
OK. This indicates that either the logi-bone or the overlay is conflicting. If you need help Jonathan or I will need to create a new overlay for your testing . In the mean time you can have a look at this great guide on the device tree and over…
-
Hi Tarik, Can you remove the logi-bone and plug in the LCD and see if it works. This will test whether the current device tree overlay is compatible. It it does not work, I think the next step would be to create an overlay that works with the …
-
Hi Tarik,It is possible that there is a conflict with the default device tree setup for the LOGI image and the use of the LCD you are trying to use. Can you provide a datasheet to you LCD you are using? We will need to look at the pin usage of the…

Hi Seather, I tested the IO toggling on the GPMC_AD pins, which did not work. The appear to be set as outputs and high after device tree setup. I did test the SS pin which worked fine. entity logibone_blink is port( OSC_FPGA : in std_logi…
-
Hi Seather, Thanks for dropping in. You are definitely taking the right approach. Your code looks fine. But, there may be a conflict with the GPMC IO state. I am not sure what the state of the GPMC_AD pins are configured to by default with an…

To update this thread: Tarik received a new camera that we shipped. The replacement camera solved the problem he was having. It seems that it is possible for the camera to become damaged, like from static sensitivity.
-
Hi There! The driver development is @Jpiat 's turf. He is currently on the road, but has been getting to email/forum as available. He should be checking back on this soon. Cheers!
-
Hi Tarik, No harm in trying..... It looks like you may need to run "sudo apt-get update" to remove the previous errors. But, it does not look like they affect your problem. Unless it is a connection problem, then it sounds like to me that it is p…
-
Thanks for the input Ize. The capital L was replaced with lower case as it started become a pain (lazy with the shift key) the repo type-case was changed to all lower case. Though the github repository is technically "logi-apps" a "git pull" into …
-
The file that needs removed is ".done" the command to remove the file is "rm -f .done" There should be a ".done" file if you have already run the app. This file is created that indicates that the app update process has taken place and prevents…
-
Hi Tarik, Can you run "rm -f .done" from the image processing directory and retry? This will force all of the library components to update which may help. @jpiat will have some more tips if this does not help. Cheers, Mike

Hi Pei, Thanks for dropping in! We are currently transitioning all of our distribution to a global distributor. We hope to have things inline to begin have orders being ready by the end of August. Sorry for the inconvenience of timing. We …
-
Glad to hear! I was going to add the idea of adding some double sided velcro tape that can be used to help to more securely attach the logi to the pi-b+. You could stick on top of the USB connectors and to the bottom of the Pi. This will give 2 s…
-
Thanks for sharing! Glad to hear your success. Keep us posted on any other efforts and requests. Cheers!
-
Hi Ize, I don't have any hardware with me now, but will do some testing tomorrow and get back to you with some suggestions. Also, @jpiat may have some suggestions for troubleshooting. Cheers, Mike
-
Hi Ize, So you can confirm the LED0 and LED1 are not doing anything( stay off)? from the logi-apps/imgproc_app can you run and let me know what happens with led0/1: "sudo logi_loader logibone_camera_R1_7670.bit" If this LEDs still do n…
-
Can you let us know what the LEDs are doing? One of the LEDs should be pulsing at 30hz which is the vertical sync. If you do not see the then the camera may be connected incorrectly or damaged. Here is s wiki page that shows how the camera shoul…
