Yes, you are right. And yes, it is only a 'work around', but a SSD is faster and saver than a SD.

I would like to learn Python, and use it on the NanoPi. Most of the examples I am seing are for the RPI.
How can I use things like I2c & SPI for it.

It is not always easy as on an Raspberry, but it works.
This may help you a bit: Using I2C on NanoPi Duo with Python

I2C works fine, but if you use a Python library, written for Raspberry Pi, remember the NanoPi Duo has 3 I2C-BUSes! First take a look at the NanoPi Wiki, because we must know which I2C Bus we are using with the 2x9 Pin Header . NanoPi Duo 2x9 Pin Header smaller.jpg OK, we are using I2C0, this is Imp...

I had the same problem, so I used both, a 8 GB SD card and a 32 GB mSATA SSD. I changed the /boot/boot.cmd on the SD (/ dev / mmcblk0p1) to (/ dev / sda2), that the SSD as / is integrated. setenv bootargs console=ttyS0,115200 earlyprintk root=/dev/sda2 rootfstype=ext4 rw rootwait fsck.repair=${fsck....
