Error in Adding a New Board Configuration

[Ivan Braga]

Just a little history.

About 3 years ago I bought this board, https://www.waveshare.com/product/mcu-tools/stm32/open/open429i-c-package-b.htm, to serve as the basis for some more elaborate testing with Nuttx.

More as usual, the lack of time made me forget about her along with others that we always buy and set aside.

That said, let's get down to business.

I copied the nuttx/boards/arm/stm32/stm32f429i-disco folder, pasted it, and named it nuttx/boards/arm/stm32/open4209i.

I changed nuttx/boards/arm/stm32/open4209i/src/stm32f429i-disco.h to nuttx/boards/arm/stm32/open4209i/src/open429i.h.

All references to “stm32f429i-disco” in the files within the folder “nuttx/boards/arm/stm32/open4209i” have been changed.

In /nuttx/boards/Kconfig:

================================================== ======

config ARCH_BOARD_OLIMEXINO_STM32

depends on ARCH_CHIP_STM32F103RB

The highlight is “nuttx///include”, makes me believe the path is not found “///“.

Any suggestions for this problem is welcome.

A typo above occurred, "nuttx/boards/arm/stm32/open4209i/src/stm32f429i-disco.h to nuttx/boards/arm/stm32/open4209i/src/open429i.h".

More yes, nuttx/boards/arm/stm32/stm32f429i-disk/src/stm32f429i-disco.h to nuttx/boards/arm/stm32/open4209i/src/open429i.h.

Taking advantage, follows copy of nuttx/boards/Kconfig

Hi Ivan,

You started the process correctly: you copied a similar board to other name and started renaming it.

Probably you missed changing some stm32f429i* to open429i. Or the CONFIG_NEW_BOARD_NAME has some typo in some places.

Try to Review all the files inside your board.

BR,

Alan

Hi Alan.
Thanks for the feedback.
I believe I have changed all (stm32f429i * to open429i). I am more likely to believe that it is CONFIG_NEW_BOARD_NAME has some typo in some places.
Attached is a zip as my configuration.
My Kconfig inside / boards, and the open429i folder inside / boards / arm / stm32.
If you or anyone can check, I appreciate it.

Ivan

Hi Ivan,

I fixed it and got the nuttx.bin generated correctly:

As you can see the firmware is too big. It is happening because you
didn't remove the features from stm32f429i-disco board (LCD, etc).

Try to figure-out what you did incorrectly, it will help to learn how
things work. In fact porting NuttX for some board similar to existent
board is really easy. In less then 10 minutes you get it done.

Also as learning exercise, please remove all not used stm32f429i-disco
features from this Waveshare Open429i board and submit a patch to
NuttX mainline. It could be useful case other people decide to test
NuttX on this same board.

BR,

Alan

Any patches coming to the mainline must be 100% clean and perfect.  Take
your time do it right:

- Remove all unverified configurations.  I only want fully tested
configurations in the NuttX repositories.

- Don't drag in any unused, garbage files from the
stm32f429i-discovery.  Every file must be used and verified.  You can
bring in other files (or configurations) later after they have been
verified.

- Make sure that the board.h header file does NOT include any stm32
files (see commit, I fixed that yesterday for the stm32f429i-discovery.

- Make sure that the code follows the NuttX coding style complete.  Run
the tools at tools/nxstyle.c to assure that every .c and .h file
conforms to the coding style.

Then, if you like I can consider a patch.
