From 2e920a212fbe2de705811d547c169c1ae1611a02 Mon Sep 17 00:00:00 2001 From: Evgeniy Naydanov Date: Wed, 22 Nov 2023 18:10:27 +0300 Subject: [PATCH] break from long loops on shutdown request In loops that typically take longer time to complete, check if there is a pending shutdown request. If so, terminate the loop. This allows to respond to a signal requesting a shutdown during some loops which do not return control to main OpenOCD loop.
