From fe642a5b1411502000af9d169122522065dff9ca Mon Sep 17 00:00:00 2001 From: Yvan Roux Date: Wed, 15 Jun 2022 16:00:34 +0200 Subject: gdb/arm: Fetch initial sp value prior to compare MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For Arm Cortex-M33 with security extensions, there are 4 different stack pointers (msp_s, msp_ns, psp_s, psp_ns). In order to identify the active one, compare the values of the different stacks. The value of the initial sp register needs to be fetched to perform this comparison.
