Re: qemu_x86 and samples/drivers/uart/echo_bot #test #uart


I've tried the 3 samples under samples/subsys/console (echo, getchar, getline) and they all have a very similar problem: no echo of my input and no error displayed when I run after building for qemu_x86 (per the directions on the Zephyr web page e.g.,  But, for these 3 samples, CTRL-a, x stops the app, so something there is processing input. 

Here's the output I see from samples/subsys/console/echo:

-- west build: running target run

[0/1] To exit from QEMU enter: 'CTRL+a, x'[QEMU] CPU: qemu32,+nx,+pae

You should see another line with instructions below. If not,

the (interrupt-driven) console device doesn't work as expected:

Start typing characters to see them echoed back

QEMU: Terminated

I typed a bunch of lines before I pressed that CTRL-a, x, but nothing showed up.

I'm running Ubuntu 20.04 LTS under VirtualBox, in case that matters.
