Thank you very much. Indeed it now works perfectly. However I would propose a little change on this. Currently board drivers require a specific directory structure, and this non-obvious (for me) config entry.
Why not instead handle external drivers exactly like external boards? That is, add CONFIG_ARCH_DRIVERS_CUSTOM, CONFIG_ARCH_DRIVERS_CUSTOM_DIR, CONFIG_ARCH_DRIVERS_CUSTOM_DIR_RELPATH etc in nuttx/drivers/Kconfig and have the user select whether they need external drivers and where should they be located, instead of implying things. Or, at a minimum, I believe CONFIG_SPECIFIC_DRIVERS could be defined in nuttx/drivers/Kconfig. Since the build system uses this symbol, nuttx should define it, instead of relying on external Kconfigs.
