Re: [PATCH v2] STM32 lwIP addition and CMake support

[Robin Mueller]

Hi Shiro,

So you mean, retain the STM32 file unchanged in the source tree and then 
applying the patch? Or copy it from somewhere and then apply the patch?


I thought of that option as well.
The only issue I see here is that I merged the (example) files provided 
by STM32 so that one file can be used for every lwIP API. I managed to 
have the same files for alle three APIs this way, which is the cleaner 
solution in my opinion. But I guess I could just take the base files for 
the Raw API provided by STM32, create the patch to add support for all 
other APIs and add all other tweaks required for RTEMS, and then provide 
that patch somewhere.


Kind Regards
Robin

Hi, Robin,

Would it be possible to retain the STM32 code, but carve out the 
“contaminated” lwIP code into a patch file.  Then RTEMS code base 
remains “clean” and if I, any user, chose to enable lwIP on STM32, I 
could do so by applying that patch.  I’d contaminate my src tree, but 
that’d be my responsibility and in any case, I’d be compliant (target 
is after all an STM32…).


The “patch trick” to manage license contamination has worked well for 
others in the past.


Cheers,

Hi,

Unfortunately, there was no other reply to the request.

Easiest solution would be to exclude the STM32 code completely out of 
RTEMS code for now. I can host it as example code in a personal 
repository.
But then I might have to change the architecture of the lwIP code 
again which provided some building blocks to make porting/using it 
easier.


Kind Regards
Robin

[PATCH] STM32H7 ethernet pin corrections

[Robin Mueller]

These patches were submitted a few months ago, but it was found out
that the default-by-family: [] were missing in the GPIO .yml lines. 
This was fixed in this patch.

This patch accounts for different pins for the ETH peripheral
on STM32H7 devices. For example, the Nucleo H743ZI has slightly
different pins than other STM32H7 boards.

[PATCH rtems-lwip v2] STM32 lwIP addition

[Robin Mueller]

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.

[PATCH] CMake support for the STM32 lwIP addition

[Robin Mueller]

This patch adds full CMake support for the lwIP support.
It can be easily extended to other architectures as well.

More information can also be found in the README, which also specifies
how to build with CMake. The waf build system still needs to be adapted
to perform the same function.

+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.
+
+The user still needs to supply the `lwipopts.h` configuration file. The port 
folders contain

[PATCH] Fixes for TMS570 BSP

[Robin Mueller]

When compiling the lwIP port for the TMS570, there
were issues with the BSP. Headers are expected in a folder
named ti_herc which did not exist. This fixes the issue.

Furthermore, there were multiple warnings about define redefinitions.
This was fixed as well.

[PATCH] STM32H7 BSP: Commented out legacy define which causes nameclashes

[Robin Mueller]

---

I had a warning related to nameclash of defines for the arm/stm32h7 BSP.
More specifically, the define PAGESIZE which is defined in stm32_hal_legacy.h
as well as in limits.h (which is located in arm-rtems6/include)

I solved the problem for now by commenting out the define in stm32_hal_legacy.h

The BSP still built without issues. I searched the stm32h7 BSP folder in the 
sources
to check whether the legacy define is actually used somewhere and it is not.

 The console driver supports the on-chip UART and USART modules.
+Different board variations use different GPIO pins and blocks for the default 
+communication UART and it is recommended to check whether the default 
+configuration provided is valid in the BSP.
+
+To specify that the BSP should be built for the STM32H743ZI-Nucleo board,
+users can supply ``STM32H743ZI_NUCLEO == True`` to ``config.ini`` when 
+building the BSP.
+
+Alternatively, users can supply the configuration structs defined in ``hal.h``
+in the applicaton for other boards. For the console driver, the 
+``stm32h7_usartX_config`` structs are used to configure the GPIO pins and 
other 
+parameters. The default implementations can be found in 
+``bsps/arm/stm32ht/console`` in the RTEMS sources.

[PATCH] command correction to perform tests

[Robin Mueller]

The old command seems to be incosistent with the rest of the quick
start guide. I was able to run tests for both RTEMS5 (released build)
and RTEMS 6 ( git clone) with the following commands.
