The necessary parameters for running Python tests on qemu are

Nit: tedious
Let's wrap the commit description to 72-74 characters; it's rather
narrow right now.
The patch adds examples for u-boot-test-console and
u-boot-test-reset.

launch the
simulator from `u-boot-test-reset` instead, while arranging for this console
process to always communicate with the current simulator instance.
Rather that adding these examples into a section that details one of the
individual hook scripts, let's create a new section "Simple qemu
example" and put it right before or after the existing "Examples" section.
+With qemu you can use the parameter -monitor to connect the control console to
a
+Unix socket, e.g.
Let's state what filename the following example should be saved to;
u-boot-test-console.
+ #!/bin/sh
+ touch /tmp/u-boot-monitor-socket
+ qemu-system-x86_64 -bios build-qemu-x86/u-boot.rom -nographic -netdev \
+ user,id=eth0,tftp=../tftp,net=192.168.76.0/24,dhcpstart=192.168.76.9 \
Let's indent the continuation lines so it's more obvious this is a
multi-line command:
asdfsd fsjkl fsfj lssfjdasdfsjl \
asdfsd fsjkl fsfj lssfjdasdfsjl \
asdfsd fsjkl fsfj lssfjdasdfsjl \
I think this (and the other) script should "exec" the commands to avoid
leaving the shell instance around.
This example seems to enable networking support in qemu, and a TFTP
server. I believe you'll need to provide an example Python board
configuration so that test/py knows to enable the network tests.
+ -device e1000,netdev=eth0 -machine pc-i440fx-2.8 \
+ -monitor unix:/tmp/u-boot-monitor-socket,server,nowait
+
+In `u-boot-test-reset` call the socat command to send a system reset:
+
+ #!/bin/sh
+ echo system_reset | socat - UNIX-CONNECT:/tmp/u-boot-monitor-socket
+ sleep 1
+ true
Why is the sleep needed? The true command shouldn't have any effect
given set -e isn't in use.
I only see examples for u-boot-test-console and u-boot-test-reset. I
believe you need to provide a dummy/empty u-boot-test-flash too.
