[PATCH rtems-lwip v2] STM32 lwIP addition
Robin Mueller
robin.mueller.m at gmail.com
Wed Apr 28 17:41:04 UTC 2021
This patch adds the STM32H7 / NUCLEO-H743ZI lwIP port.
It also improves the architecture to make integration
of new BSPs easier. The patch continues the wscript file to
allow installing the lwIP support similar to how a RTEMS
BSP is installed.
https://github.com/rmspacefish/rtems-stm32-lwip is a self-contained
repository to test the lwIP integration for the arm/stm32h7
and arm/nucleo-h743zi BSP. The repository README specifies
how to build the RTEMS lwIP support and install it at a specified
prefix location.
The STM32 port includes the LAN driver (lan8742.c), the
primary port functions in ethernetif.c and some application code
taken from CubeH7, which can serve as a starting point for
implementations and was also tailored to RTEMS.
The common source file were refactored to be more generic and independent
of the used BSP.
This patch includes corrections from the code review by Gedare Bloom.
Please note that any merges need to be held off until some licensing issues
with STM concerning the SLA0044 license on example files are resolved.

+RTEMS lwIP Repository
+======
+
+This repository contains the RTEMS lwIP support and all available ports.
+Currently, the following RTEMS BSPs are supported:
+
+ - All `arm/tms*` BSPs.
+ - The `arm/stm32h7` and the `arm/nucleo-h743zi` BSP. An example application can be
+ found [here](https://github.com/rmspacefish/rtems-stm32-lwip).
+
+# Using this repository
+
+The repository contains the lwIP sources, the OS port for RTEMS and port files
+belonging to a RTEMS BSP.
+
+It is recommended that the user supplies the `lwipopts.h` configuration file. The port folders
+contain template option files to get started. The user can copy and rename this files into the
+application and then pass the include path to the build system using the `--lwip-opts` option.
+
+# Building with waf
+
+It is assumed that the path(s) containing the `lwipopts.h` file was stored in the environmental
+variable `LWIP_OPTS_PATH`, the install prefix is stored in the environmental
+variable `RTEMS_PREFIX` and the RTEMS BSP is stored inside `RTEMS_BSP`.
+The lwIP support can now be built like this:
+
+```sh
+./waf configure --prefix="$RTEMS_PREFIX" --lwip-opts="$LWIP_OPTS_PATH" --rtems-bsp="$RTEMS_BSP"
+./waf
+./waf install
+```
