Прошу помощи с подключением акселерометра adxl345. Прошивка не видит его. Одноплатник Rock Pi 4. ОС: Debian 10 buster. Плата управления SKR 1.3. Все устанавливал по инструкции с сайта https://www.klipper3d.org/Measuring_Resonance. Все необходимые пакеты установлены. Правильность подключения пинов gpio одноплатника и выводов акселерометра десятикратно проверена. Провод 50 см dupont. Команда терминала ls /dev/spi* выводит /dev/spidev2.0, т.е. spi шина включена. В веб интерфейсе fluidd прошивка выдаёт ошибку: mcu ‘rpi’ shutdown: Unable to open spi device. Акселерометры(2 шт.) покупал на АлиЭкспресс. Возможно дохлые, но сомнительно, чтобы сразу два. Проверить их больше не на чем. Может еще есть какие нюансы, может что то забыл сделать, подскажите пожалуйста. Очень хочется на своей дельте резонансы убрать.

I’m trying to run a C-program via html.
I’m using Raspberry Pi B and PiFace Difgital I/O (1).
I use a html.index, piface-blink.php and the C-program piface-blink.c
When I run the c-progam it access OK and blinc the LED at PiFace.
When I try to run i through a web I get this error message in /var/log/apache2/error.log:
Unable to open SPI device: Permission denied

This is what I have done so far:

pi@Cisero ~ $ uname -a
Linux Cisero 3.18.7+ #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 armv6l GNU/Linux

Access through web, http://cisero_wifi/check/

I have opened SPI by raspi-config.

My question:
What else do I have to do or what does I had done wrong?
Edit:
For some reason I don’t understand the program begun running with success. :)

From a fresh install I can get octoprint and klipper talking and can see what look to be accurate temps. Every time I get to the step «M112» the system will not recover. I have of course entered «FIRMWARE_RESTART» but am met with T:0 and a status reply of

Recv: // MCU ‘host’ error during config: Unable to open spi device
Recv: // Once the underlying issue is corrected, use the
Recv: // «FIRMWARE_RESTART» command to reset the firmware, reload the
Recv: // config, and restart the host software.
Recv: !! Error configuring printer

I have had this same hardware running on klipper with ramps prior. I have the onboard flashed with redeem and can boot into klipper at any time to test. Would love to cut over to klipper as I am really struggling to get good prints out of redeem.

That’s odd. What does ‘ls -l /dev/spidev*’ report? There should be
an spi device created by the OS.

…

@ifUpEth0

ls -l /dev/spidev* gives error. It would seem the spi device is missing. I see nothing like it in /dev.
I can try a new snapshot but when I tried bone-debian-9.3-iot-armhf-2018-01-28-4gb I could never get past the «/dev/rpmsg_pru30» error mentioned above.

@ifUpEth0

the spi tip helped. Should anyone else end up here. Check /boot/uEnv.txt.
You probably need the following:
cape_disable=bone_capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0,BB-SPIDEV1
After this and a reboot I again have my temps and can M112 and FIRMWARE_RESTART as expect.

The «cape manager» stuff on the beaglebone is a complete nightmare.
:-(

I suspect issue #183 is a similar (but different) mysterious problem
with the cape manager.
