Все произошло во время того, когда я пытался поднять сервер mongoose на плате stm32-e407 с контроллером stm32f407zgt6. До этого хардфолты возникали довольно часто, но как-то удавалось от них уходить не разбираясь до конца, в чем же все-таки дело, но видимо время пришло:
Делаю проект с помощью CubeMX на eclipse (генерирую для truestudio), в проекте включен FreeRTOS версии 8.2.1 с heap.4, включены кварцы, программа падает в функции localtime в StartDefaultTask, НО, если расскоментировать такие же три строчки перед osKernelStart, то и в таске оно не упадет. Хотелось бы разобраться в чем проблема или хотя бы куда копать, ниже код и содержимое регистров после ХФ:

Добавлю, попробовал обновить FreeRTOS до V9.0.0rc2, ничего не поменялось
