w8jcik opened a new issue #2206:
URL: https://github.com/apache/incubator-nuttx/issues/2206
## Setup
With following directory structure
```
/base
/nuttx (incubator-nuttx)
/apps (incubator-nuttx-app)
/board (empty folder)
```
```
cd base/nuttx ; ./configure.sh hymini-stm32v:nsh2
```
Bulids and runs.
Then I try to use `CONFIG_ARCH_BOARD_CUSTOM` functionality, with
`hymini-stm32v:nsh2`, by making a copy of it and trying to build NuttX. This
particular board is just an example.
## First attempt
Copied content of
https://github.com/apache/incubator-nuttx/tree/master/boards/arm/stm32/hymini-stm32v
into `/board`.
Using `make menuconfig` selected
```
CONFIG_ARCH_BOARD_CUSTOM=y
CONFIG_ARCH_BOARD_CUSTOM_NAME=custom-board # description says it is not
relevant
CONFIG_ARCH_BOARD_CUSTOM_DIR=../../board
CONFIG_ARCH_BOARD_CUSTOM_DIR_RELPATH=y
```
Issues at this step:
1) If I specify `CONFIG_ARCH_BOARD_CUSTOM_DIR` wrongly, it is not possible
to run `make menuconfig` anymore.
2) If I specify correctly, it is not building.
## Second attempt
I guess `tools/configure.sh` should be used for this somehow
```
tools/configure.sh -h # doesn't give any related help
USAGE: tools/configure.sh [-E] [-e] [-l|m|c|g|n] [L] [-a <app-dir>]
<board-name>:<config-name> [make-opts]
Where:
-E enforces distclean if already configured.
-e performs distclean if configuration changed.
-l selects the Linux (l) host environment.
-m selects the macOS (m) host environment.
-c selects the Windows host and Cygwin (c) environment.
-g selects the Windows host and MinGW/MSYS environment.
-n selects the Windows host and Windows native (n) environment.
Default: Use host setup in the defconfig file
Default Windows: Cygwin
-L Lists all available configurations.
-a <app-dir> is the path to the apps/ directory, relative to the nuttx
directory
<board-name> is the name of the board in the boards directory
configs/<config-name> is the name of the board configuration sub-directory
make-opts directly pass to make
tools/configure.sh ../../board # refuses
File Make.defs could not be found
tools/configure.sh ../../board:nsh2 # refuses
Directory for ../../board:nsh2 does not exist.
tools/configure.sh ../../board/configs/nsh2 # this works, but it is not
consistent with normal usage of this command and absent from help or
documentation
```
It builds, but it just configures `hymini-stm32v:nsh2` as far as I can tell.
So I am changing `/board/configs/nsh2/defconfig`
```diff
-CONFIG_ARCH_BOARD="hymini-stm32v"
-CONFIG_ARCH_BOARD_HYMINI_STM32V=y
+CONFIG_ARCH_BOARD_CUSTOM=y
+CONFIG_ARCH_BOARD_CUSTOM_NAME=custom-board
+CONFIG_ARCH_BOARD_CUSTOM_DIR=../../board
+CONFIG_ARCH_BOARD_CUSTOM_DIR_RELPATH=y
```
It is not building afterwards.
```
make distclean
tools/configure.sh ../../board/configs/nsh2
```
```

```
## Conclusion
This functionality is difficult to use.
Receipe for doing this is missing from documentation.
I am not sure what I am missing, analysed Makefiles a bit and searched
through different mailing lists of NuttX with some solutions present there, but
it doesn't help me solve this. It would be great if it would be easier.
Reading this doesn't help
