From a64eb336c4a8d3f9c160aa30b81033e3ad7227d8 Mon Sep 17 00:00:00 2001 From: hathach Date: Sat, 30 May 2026 00:52:22 +0700 Subject: [PATCH] dynamic_switch: hoist while(1) out for OS_NONE Sonar flagged the loop body as executing only once on OS_NONE because the OS_NONE branch returns inside the first iteration (main() drives the task again). Make the while(1) conditional on RTOS so the OS_NONE build is a straight-line function with no misleading loop.
