Hello guys
I’m beginner and new to the NAVIO2 / Raspberry universe and I have some questions:
I have a Mac 15” Retina (OS El Captain), NAVIO2 and Raspberry PI 3 b.
On the site where there is documentation on the NAVIO2 “https://docs.emlid.com/navio2/Navio-APM/configuring-raspberry-pi/” and did not understand some things:
- is described:
"Downloading configured Raspbian image”
Navio2 requires the Raspbian preconfigured to run. We provide a unified SD card image for Raspberry Pi 2 and 3. The OS is headless, i.e. it comes without the GUI it is not required for drone applications. "
Questions:
I downloaded the RASPIAN “05/27/2016-raspbian-jessie.img” using the link “Raspberry Pi OS – Raspberry Pi” and realized the SD CARD installation procedures and put in Raspberry PI and it worked when I put the HDMI cable to the TV without any OS/SW NAVIO2.
The question is: I have to download the image NAVIO2 “emlid-raspbian-20160718.img” and uncompress it into the same SD Card where this installed Raspbian?
I ask this because when when I use the command to create the image on the SD CARD
“sudo dd if = / Users / fabioferreira / Downloads / 27.05.2016-raspbian-jessie.img of = / dev / rdisk2 bs = 1m”
it destroys all SD CARD data.
I tried to create the image without Raspbian, only using the information provided on the site EMILID “https://docs.emlid.com/navio2/Navio-APM/configuring-raspberry-pi/”
“Sudo dd if = / Users / fabioferreira / Desktop / NAVIO2 / emlid-raspbian-20160718.img of = / dev / rdisk2 bs = 1m”
But when I put the HDMI cable into the Raspberry PI 3 he gave no video signal.
What could be going wrong?
Please help me.
