Not able to login nor ssh into the FPGA.

I followed the installation steps for both DE1 images (i.e. 20190521_DE1_0.2.0b.img and 20200124_DE1_v0.2.1.img) and I cannot ssh into the FPGA. In fact, I cannot even log into the board via the serial port (i.e. ttyUSB0 because it never gets into the login stage).
The DE1-SoC boots well using the Terasic LXDE image.

Output via the serial port

The latest SD image for the DE1 platform is 20200124_DE1_v0.2.1.img, so you should be using that.

As for why it is not going into the login screen, check that the dipswitches have been set correctly, according to: https://www.nengo.ai/nengo-de1/getting-started.html#setup-the-de1-soc-board

Also, just to check, do you see 4 red leds light up and follow a binary counter pattern after you power cycle the board?

HI @xchoo ,
It worked, the problem were the dipswitches. Many thanks
