From 8515da60a80880db1f4c632a1ecfef383f6136d8 Mon Sep 17 00:00:00 2001 From: Marc Schink Date: Tue, 16 Aug 2016 18:36:27 +0200 Subject: [PATCH] jlink: Adjust log verbosity of libjaylink Currently, the log verbosity of libjaylink is not accessible from the user interface. Therefore, changing the log verbosity of libjaylink is only possible from within the J-Link driver source code which is not acceptable for end users. Output the libjaylink log messages through the logging module of OpenOCD rather than directly to stderr.
