rootfs issue #5

Closed ramcn closed 5 years ago

ramcn commented 5 years ago

Hello,

I followed the README and am able to successfully get to a point of launching the simulation and opening the console of the target RISC-V machine and login.

However, when I run the mentioned test (solo.sh) I see a failure to open the dla device. I am suspecting the required kernel modules are not part of rootfs. As seen the attached log the /usr/modules does not exists in the rootfs.

Any idea what could have gone wrong? Can I get some advise on how to debug this issue?

PS: attached console log. isssue1.txt

Thanks, Ram

I was able to resolve the issue by redoing all the steps fresh from scratch. And am able to run the YOLOV3 test.

I guess I might have missed some step like (./marshal -v build workloads/br-base.json) or had an incorrect config_runtime.ini. Not exactly sure what fixed the issue.
