STM32F407, LwIP, FreeRTOS socket - connect infinite loop in vPortRaiseBASEPRI

Hello everyone,

Testing LwIP + FreeRTOS on my devboard.

Everything configured by CubeMX.

each time I use 'connect' function I ends up in infinite loop inside vPortRaiseBASEPRI

I have strong feeling that has some correlation with interrupt priorities.

Additional information:

Ethernet - use RMII interface

SYS clocked from Timer 14...

Socket crated from main thread.

Thanks in advance

Update.

 Looks like it has some correlation with UART1 interrupts...

update.

manually (CubeMX does not allow to increase priority of USART interrupts) increased priority of USART1 IRQ from 5 to 4.

so far so good...

Hi

Rare to see someone that has exacly the same problem as me.Did that change solve your problem ? Whats weird is that I have the same problem but I don't have any UART enabled.Got any idea what it could be ?I only have ethernet , LwIP and Free RTOS enabled.

Working so far. No deadlocks. Now I have issues with lwip timeouts ....

Receive never ends if other side didn't close a socket....
