From 30e3ce99a7dc7aef9c388e0ebc05018b4c4ba721 Mon Sep 17 00:00:00 2001 From: Tom Gall Date: Fri, 8 May 2020 14:42:35 -0500 Subject: [PATCH] A clone of test/python/unittest/test_runtime_micro.py, however modified to run specifically on ARM cortex-M hardware, which currently is just the STM32F746 discovery board.
