From 1b53af2e88492a57d6e74107e4ee3463a18c4e29 Mon Sep 17 00:00:00 2001 From: Mahavir Jain Date: Tue, 12 Nov 2019 22:36:30 +0530 Subject: [PATCH] freertos: modify configASSERTs around scheduler state check Regression introduced in commit 79e74e5d5f948e585bec586db7f482a2f2df50dc It is possible that some FreeRTOS APIs are invoked prior to scheduler start condition (e.g. flash initialization in unicore mode). In that condition these asserts should not trigger (scheduler state being yet to be started), hence changes per this fix. --- components/freertos/tasks.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/components/freertos/tasks.c b/components/freertos/tasks.c index 72ebefbde7..5294b5d204 100644 --- a/components/freertos/tasks.c +++ b/components/freertos/tasks.c @@ -1302,7 +1302,7 @@ static void prvAddNewTaskToReadyList( TCB_t *pxNewTCB, TaskFunction_t pxTaskCode //No mux; no harm done if this misfires.
