Spresense SDK: Failed with section `.bss 'will not fit in region `ram' error on nuttx link

Google Translation Section .bss' does not conform to region ram'

The bss section is where variables that are not initialized are placed.
Perhaps these variable areas have grown larger and exceeded the RAM area.
You must reduce these sizes or change the placement/assignment of sections to avoid exceeding them.

Flash memory is a memory that can only be rewritten in special steps.
Variables cannot be placed in this area.
