dummy folders in nuttx tree

Hi guys,

Looking at nuttx folders I saw two folders called "dummy", specifically
nuttx/dummy and nuttx/drivers/dummy. The last one is referenced by the
symbolic link nuttx/drivers/platform. What is the reason for this?

Thanks

Hi Daniel,

I think that it is possible to replicate the changes from Spresense for your own board

Please check: 
tool/Unix.mk
boards/arm/cxd56xx/drivers/Kconfig
drivers/Kconfig

Best regards
Alin

Hi Alin,

So, I suppose that if I have a custom driver that I have no reason to share and I want to keep it outside the NuttX folder tree, I can point the nuttx/driver/platform symlink to the custom driver folder. Doing this the Kconfig will appear on menuconfig. Is this correct?

If this is correct I am doing something wrong because it does not work for me. When I configure the board the symlink I just created is overwritten to original configuration, and restoring the symlink does not work either.

How should I proceed to build a custom driver outside the NuttX folder tree using this approach?

Thanks

Hi Daniel,

There are boards (ex Spresense) that use drivers that are unique for those platforms 
In this case we use the symlinks to drivers folder but keep the drivers under the specific board that uses them 

Best regards
Alin
