If none is set in the BSP Editor option setting, the option description will be lost in the makefile, and a Null Pointer error will occur when changing from none.

for example,
If BSP_CFLAGS_DEBUG is set to none, BSP_CFLAGS_DEBUG will not be described in makefile.
To enable the option again, you need to edit the makefile directly and add the following description of BSP_CFLAGS_DEBUG.

# C/C++ compiler debug level. '-g' provides the default set of debug symbols
# typically required to debug a typical application. Omitting '-g' removes
# debug symbols from the ELF. This setting defines the value of
# BSP_CFLAGS_DEBUG in Makefile.
BSP_CFLAGS_DEBUG = -g
