Boot in emergency mode #160

Hi, I just programed the VC707 with a bitstream of a Rocket core + a Gemmini 16x16 accelerator. But when I plug the sd card on and try to boot Linux the output shows the folling message and the subsequent error:

You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or "exit"
to boot into default mode.
Give root password for maintenance
(or press Control-D to continue): 
root@debian:~# exit
exit

[  OK  ] Reached target Network.

I noticed that using the provided vc707 bitstream on the releases area this does not happen.

What is happening?

I fixed it with a design with 2 rocket cores.

I have this problem again when trying to run one boom core. And this time I can't add another core. My configuration is as follows.

class Boom64m1gem16 extends Config(
  new WithGemmini(16, 64)  ++
  new WithInclusiveCache  ++
  new WithNBreakpoints(8) ++
  new boom.common.WithNMediumBooms(1) ++
  new RocketWideBusConfig)

Any solution, please?

The timeout problem is addressed in the latest code, you need to rebuild SD card. To make sure you use the latest code, do a clean build:

git clone https://github.com/eugene-tarassov/vivado-risc-v.git
cd vivado-risc-v
make update-submodules
./mk-sd-card

I already updated it and rebuild the sd card when you indicated so on another issue.

As said on another issue https://github.com/eugene-tarassov/vivado-risc-v/issues/164 it was a problem with my sd card image. Solved now.
