I am using STM32F429ZIT6 on a custom PCB
- FreeRTOS API : CMSISv1
- LWIP v2.1.2
- Ethernet PHY : LAN8742A
I am trying to handle cases when link is up or down
if I call
MX_LWIP_Init();
before
osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 2048); //was 2048
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
then StartDefaultTask thread doesnt run but the Ethernet link handler thread runs.
Any Idea what is preventing those two threads to run ?
