Hi there,
I have a STM32F746 Nucleo-144 board which is connected to another device using the ethernet port. This works well as long as there are no other interrupts used outside of the network code. But it becomes unstable (device connected to the Nucleo stops sending data) as soon as I am using Timeout interrupts.
Best example I came up with
So the function foo() creates an interrupt loop (reattaching if the timeout is triggered. The code works for 30 seconds before the connected device stops its data stream. The data stream is contains 1108 byte packages sent with 125Hz. I have experienced the same issue if the receive buffer runs full - But this should not happen here because the interrupts don't do much and the data should be received fast enough.
I am completely out of ideas - Would appreciate any help. Thanks
