Read and tried the logi-wishbone info/demos, all worked as indicated in the documentation. If I understand the concept correctly, I can send the counter_output to a memory location on the fpga (e.g. 0x000A), then use either python or C (e.g. read_…

Thanks for the quick reply. 1. Will this Verilog code work as a "combined" clock generator and counter? module 8_bit_counter ( clock, //OSC FPGA 50Mhz input_signal, //input signal for the counter on PMOD1 pin2 reset, // Pushbutton0…

I tried the startup script idea, and it works. Below is the /etc/rc.local file I modified, in case anybody is interested. Thanks. #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the scr…

I probably will try the startup script idea first. Appreciated the info. I'll study/research. Thanks.

As always, thanks for the quick response and the explanation. Yes, it does help. I'll research/learn the loading the onboard flash/*.mcs file part. As for xlinix jtag adapter, I have an Altera USB Blaster Jtag adapter (for an Altera MAX development …

Now I have the desired booting behavior, which is the same as mjones'. Here are what I did, in case they are helpful to others: 1. Re-flashed emmc with the "BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz" 2. Inserted logi image SD card 3. Boote…

Beaglebone Black board is marked as "A6" on the side of P8 header(purchased in year 2000, I think), and running Linux debian-armhf 3.8.13-bone30 #1 SMP Thu Nov 14 02:59:07 UTC 2013 armv7l GNU/Linux on emmc. Just want to clarify: 1. Current behavio…

mjones, Thanks for links. I am using pre-built logi image (logibone_r1_ubuntu_v4.img) on the sd card. Is this the same as yours? After booting from sd card, the uname command shows this: ubuntu@arm:~$ uname -a Linux arm 3.8.13-bone40 #3 SMP Mon Ap…

Joanthan, What are the steps to restore the EMMC bootloader if needed? I am going to try your steps soon. Thanks. mjones, I would prefer what you described but I don't know how to make it happen.

Hi Tarik, I noticed in your last post, you did "cd Logi-apps". In my case "Logi-apps" came with the logi ubuntu image. To get the updated apps, I did "git clone -b logibone https://github.com/fpga-logi/logi-apps.git", then I have a "logi-apps" di…

It is working for me now after I ran the init_eeprom.sh. I am sorry that I may have misunderstood the Logi-bone quick start guide instruction --- I thought only earlybird boards needed to run that. Thank you, Jonathan, Mike and Ribbox for all your…

When I attach file, insert/embed the photos here, the images seem to be over-zoomed/unclear. So, I'll be sending them to support@valentfx.com. Thanks.

Hi mjones, 1. Yes, confirmed -- the LED0 and LED1 stay off, doing nothing. 2. After doing the following, ubuntu@arm:~/logi-apps/imgproc_app$ ls logibone_camera_R1_7670.bit make_demo.sh README.TXT ubuntu@arm:~/logi-apps/imgproc_app$ sudo logi_loade…

Ribbox and mjones, Thanks for the replies. The len cover is off. I tried the entire length of len screw. Same result. The video area in my case is not black, it is blank (white, no color). Only two LEDs on logi-bone are on (steady) --- the PWR LED …
