Hi, the FPGA is configured only through i2c and SPI. The I2C is used to drive a IO port expander that control the slow signals of teh configuration (init, prog, done) and the spi is used to send teh bitstream. If you have a look at the linux code f…

Hi, This seems like a very interesting project. If you succeed you will end up with a neo/retro computing platform ! The core as presented on opencores should fit on the spartan 6, but you will have to tweak the project because it may use some reso…

Please as a replacement to e14, the board seems to fail. Sorry about that. Regards, Jonathan Piat

I just did a fresh install of raspbian et it worked out of the box. Here is what i get with i2c-detect : sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- --…

Can you try an i2c-detect on the i2c-1 bus ?
-
did you enable the I2c in the /boot/config file and i2c-dev in /etc/modules ? To enable SPI on latest raspbian distro, edit /boot/config.txt (as sudo) and add : dtparam=spi=on To enable I2C on latest raspbian distro, edit /boot/config.txt (as su…

Hi, there was some changes in the earliest kernel that will prevent the logi-bone to work. For now you have to stick with the older (yet not so old) image we provide. The change that breaks logi support for now are in the cape management system tha…
-
What version of the LOGI-PI are you using ? Can you copy-paste the sequence of messages after executing the loader ?
-
Great ! Yes to have to reboot for the i2c to be enabled after modifying the /boot/config.txt and /etc/modules
-
you have to prefix the command with sudo : sudo ./logi_loader ../../logi-apps/blink_led/logipi_blink.bit
-
can you do in unified loader : make clean make logipi_loader after that you should have a logi_loader executable in the directory. Do a : ./logi_loader ../../logi-apps/blink_led/logipi_blink.bit to assess the loader is working. Regards,
-
The image you use do not seem to be up to date as the message from logi-loader are from the old loader. For the fresh debian that you are trying to configure, did you : - clone logi-tools ? - in logi-tools, ran the script install_logipi.sh ? The …
-
sorry but looking at your message it seems that you are compiling the beaglebone black loader ... If you are using a pre-configured image you should not have to compile anything and if you are building your own image, you should just run the install…
-
Can you answer the question sin the following check-list : - do you use a pre-configured image downloaded on our website ? - did you run the install_logipi script in the logi-tools folder ? - where did you run the make install command you show (the …

The interface module generates vsync (just as the camera protocol), hsync (not href from the camera protocol) and a pixel clock which is more a pixel enable that is synchronous to the system clock and is half the frequency of the camera pixel clock …

The SPI pins of the FPGA are left floating if the FPGA is not configured. Pins 11 and 12 of the raspberry pi connectors are also used to set the programming mode (self boot from flash or slave serial configuration), depending on the state of these p…
-
The i2c is not used on the LOGI-Pi v1 so i guess that the problem comes from the SPI. The display problem occurs even if the FPGA is not loaded ? One problem that can also occur is that the FPGA config pins are exposed on the raspberry pi GPIO heade…
-
Hi, we don't have a specific device-tree overlay for the LOGI-Pi. The LOGI-Pi requires to have spi and i2c enabled and both can be activated using the dtparam argument in the config.txt (see logi-tool github page). The SPI piTFT usually uses the S…
-
Great ! You messages you see are the one from the new loader and you can see that your board was identified as a LOGIBONE_R1.5. Don't hesitate to ask on this forum if you encounter any problem, we will be happy to help.
-
No further changes for LOGI-Bone, the new install logibone script installs the unified-loader which adapts itself to the board version.
-
Sorry but appears that i sent the link with the old image for logi-bone, here is the correct link : http://valentfx.com/doc/logi-image/logibone/logibone_150429_ubuntu-14.04-console-armhf-2014-08-13.img.zip you don't need to re-run the eeprom initi…
-
no worry, the two first line will only work for V1 logibone, it is supposed to fail for v2 logi-bone. After running the script and re-booting, can you load a bitstream ?
-
Hi, sorry that the process oes not got smooth for you. If you burn one of our pre-configured image to the BBB : http://valentfx.com/doc/logi-image/logibone/logibone_150429_ubuntu-14.04-console-armhf-2014-08-13.img.zip(updated) what you only need …

Hi, to install the loader, just downoad the logi-tools github repository (https://github.com/fpga-logi/logi-tools) git clone https://github.com/fpga-logi/logi-tools.gitcd ~/logi-tools/logipi_loader make clean make PI_VER=PI2 sudo make install …

Are you sure that the console message you copied in the forum are the one you got from your Rpi ? These messages are not generated by the latest github version ...
-
Can you add the following line to your boot/config.txt file : dtparam=i2c_arm=on
-
I have started to work on a 3D printed case for LOGI-PI a while ago but never obtained something i'am super satisfied with. Another option is to use a case composed of a plexi sandwich and just 3D print the top to protect the LOGI-PI.
-
Hi, Can you copy paste the messages of the console when trying to load the FPGA ? Regards, Jonathan Piat
-
I would never have think of this ! This means that termios has XON/XOFF enabled by default ... there must be some way of disabling it by software.
-
There is no obvious reason I can think of ... Is the tx output wired to a pc/raspberry/microcontroller ? The only reason I can imagine is a baudrate mismatch or that those two values have a typical waveform that can make them misinterpreted by recei…
