Trying to get Ethernet, LWIP and FreeRTOS working on the STM32H745. Testing on the NUCLEO-H745ZI-Q using FW_1.7 and the STM32CubeIDE. ## Instructions on how to get started: * [LWIP without RTOS](Documentation/lwip_nortos.md) * [LWIP with RTOS](Dcumentation/lwip_rtos.md) ## Bugs and improvements * [SysTick not increasing ticks](Documentation/no_systick.md) * [No DHCP IP when starting without ethernet cable](Documentation/dhcp_nocable.md) ## Current status: * RTOS works (blinky) * LWIP works (nucleo board gets IP from DHCP on router) * HTTP test server works (navigate to http:///index.html for demo)
