Description

cpu/stm32/ldscripts/stm32.ld:
ccmram_length = DEFINED( _ccmram_len ) ? _ccmram_len : 0x0 ;
ccmram_length defined with the value of "_ccmram_len". But there is no "_ccmram_len" at all, so "ccmram_length" always has the same default value "0x0"
In cpu/stm32/Makefile.icnlude we define "_ccmram_length":
LINKFLAGS += $(LINKFLAGPREFIX)--defsym=_ccmram_lenght=$(CCMRAM_LEN)
I think that it should be:
LINKFLAGS += $(LINKFLAGPREFIX)--defsym=_ccmram_len=$(CCMRAM_LEN)
