basic test error #1
Comments
Hi, you need to build the basic on both x86 and arm nodes, using the same version of |
Thanks! But I just build the basic on both x86 and arm and using the same version of musl-gcc
Also, I just put them to the same location on each node, but it still run with error.
And if I run it separately, it will run correctly.
How to fix it? thanks |
Hi, could you enable the debug information especially on the x86 side, and share us the log? Also, could you share us the binaries you have (basic.x86 basic.arm)? |
OK, I will share the binaries now and log later, I send binaries to your email xiaoguang@vt.edu, thanks! |
I have the log now

Hey, thanks for the log. This is actually a bug/enhancement. The problem is caused by the hardcoded pseudo STDIN/STDOUT file locations in
So, if you use ssh to connect to the VMs, and do it on the ssh client it should work.

Thanks! popcorn@x86:~$ ps
PID TTY TIME CMD
618 ttyS0 00:00:00 bash
663 ttyS0 00:00:00 ps I just keep this two terminal and use ssh connect the VMs, now the tty change to pts/0 popcorn@arm:~/mvx$ ps
PID TTY TIME CMD
232 pts/0 00:00:00 bash
252 pts/0 00:00:00 ps And the mvx demo run correctly. Why can`t I inter pts/0 TTY just when I create the VMs? |
Hello. When I run mvx basic test on arm, I got this error on x86 kernel, It seems to be the filename or command error, but I don`t know how to fix it. Would you please help me, thanks!
I make this experiment on qume
