Re: image backup|restore

Правильно ли понимаю, что для того чтобы сделать backup stereopi образа достаточно подключиться через microusb. Использовать rpiboot. И далее через win32 disk imager сделать backup. Restore также как и заливка первоначального образа raspberry - через win32 disk imager. Или есть нюансы ? Да, так и е...

Re: ROS preinstalled image

То есть вы просто запустили ноду стереокамер и вещали в сеть на машину с образом ROS ? Нет. ROS был запущен на борту StereoPi, которая стояла на машинке. А картинки брались с камер. Ноды стереокамер были запущены для того, чтобы скормить поток с камер в ROS штатным способом. Мы пока не сделали родн...

Re: wifi dongle

Not all dongles work perfectly on Raspbian. The most cheapest on aliexpress https://ru.aliexpress.com/item/32819666725.html?spm=a2g0s.9042311.0.0.274233edqPggDL doesnt. To start it working tons of steps should be done because of driver missing. Waste of money and time. Moreover the speed of wifi sh...

Re: StereoPi Not Booting

Знаю об этой особенности raspberry. Шнур сразу включен в порт. И какое-то время он выдавал видео. Теперь просто черный экран, при этом нет сообщения "нет сигнала" (для ситуации, когда шнур вообще не подключен). Наверно порт убило статикой. Там стоит защита от статики, но все сценарии конечно не пре...

Re: ROS preinstalled image

Готового нет, вот как мы проводили эксперимент с образом от Ubiquity Robotics:

We have no special ROS images, and used ready-to-use images from Ubiquiti Robotics:

Re: StereoPi Not Booting

If your HDMI port seems not working (black screen through HDMI) and you want to use Raspbian with OpenCV. You have to make blind ssh install to enter the raspberry. After burn the Raspbian image, connect usb-keyboard, ethernet cable to stereopi and boot. Then press keys on usb-keyboard blind: CTRL+...

Re: StereoPi Not Booting

У меня та же проблема с Compute Module 3+ . И это похоже на то, что сгорел HDMI порт. Если использовать SLP image, то программа с Compute Module 3+ в браузере работает как и сами камеры. Raspbian c OpenCV тоже вроде как грузится, только там вход по ssh по умолчанию отключен как и VNC. Как его вслеп...

Re: How to get SPI0 working

Hi dusinnhht, Which pins are you using for SPI0? If we'll look inside Compute Module datasheet , page 18 and 19, we can see that SPI0 can bu used either at GPIO 7-10 (ALT0), or at GPIO 35-39 (ALT0). And if we'll look inside our device tree configuration ( dt-blob.dts ), we can see that some of these...

Re: Arducam

I can suggest it is an issue with I2C configuration. Both Arducam drivers and StereoPi's device tree (dt-blob.bin) describes it's own usage of I2C. 1st notice: StereoPi's dt-blob.bin loads by Raspbian only in the case, when Raspbian detects Compute Module while boot. That is, if you instert the same...

Re: Arducam

Hi Fshero, I looked at this module's description (by following your link). But all the docs tells me, that it uses 22 pin cable, but not 15 pin cable like Pi cameras. But on your photo I see 15 pins cable. Are you using some adapter/converter 22->15 pin? Could you please give me a link to the docs f...
