I want to make a new SD card with Raspbian and OpenCV installed. Instead of making it from scratch, I have already done this from another SD card that I use with raspberry.
After cloning the SD card, I can't connect to the cloned SD card with Raspberry, and the filesystem is so different from the SD card that I cloned.
I have used the
dd command in Ubuntu:
sudo dd bs=4M if=/dev/mmcblk0 of=raspbian.img
In the new SD card
sudo dd bs=4M if=raspbian.img of=/dev/mmcblk0
I get the following error when connecting the pi 2 with a HDMI cable to a laptop : end kernel panic - not syncing : VFS : Unable to mount root fs on unknown-block (179.2) Is there any method to clone SD cards with possibility to use and connect both after the cloning operation?
Note : the two sd cards have the same size : 32 GB . But they are from different types (manufacturers), the cloned one is a samsung class 10 32 gb --> cloned to kingston 32 gb class 4
