#1198 breaks compilation for all STM496 with less than 169 pins Topic is solved

[JSStabl]

We're using 20.3.x, refer to this topic: viewtopic.php?f=35&t=5946

Basically the STM32_HAS_GPIOI flag was set to true for all STM496, but there are some packages that don't have a GPIOI.

Hi,

Exactly which device is failing?

For example the STM32L496Vx Series, with the LQFO100 footprint. Whereas the STM32L496Ax series with UFBGA169 would work.

Hi,

Not sure how to handle this, headers do not make differences among packages, GPIOI is always defined, any idea?

Giovanni

[Giovanni]

Hi,

Question, is the device actually crashing on GPIOI initialization or it is simply doing a useless initialization? Compilation is fine.

Yeah we had this part in our board.c

Code: Select all

#if STM32_HAS_GPIOI
  {VAL_GPIOI_MODER, VAL_GPIOI_OTYPER, VAL_GPIOI_OSPEEDR, VAL_GPIOI_PUPDR,
   VAL_GPIOI_ODR,   VAL_GPIOI_AFRL,   VAL_GPIOI_AFRH,    VAL_GPIOI_ASCR,
   VAL_GPIOI_LOCKR},
#endif

Which wasn't defined in the board.h, maybe we need to figure out how to fix that on our side.

Hi,

Re-generating board files should fix it.

The solution is not to keep generated board files in your repo. Generate them as part of your build. Giovanni, I would encourage you to do the same. But that would require your users to install fmpp ..

[JSStabl]

Can you elaborate on how to generate the board files as part of the build?

Sure, add this to your makefile:

Code: Select all

BOARD_GEN_FILES = $(BOARDDIR)/board.c $(BOARDDIR)/board.h $(BOARDDIR)/board.mk
BOARD_TEMPLATE_FILES = $(BOARDDIR)/cfg/board.chcfg $(BOARDDIR)/cfg/board.fmpp

.PHONY: PRE_MAKE_ALL_RULE_HOOK
PRE_MAKE_ALL_RULE_HOOK: $(BOARD_GEN_FILES)

$(BOARD_GEN_FILES) &: $(BOARD_TEMPLATE_FILES)
   @echo "Rebuilding board files"
   @echo
   @fmpp -C $(BOARDDIR)/cfg/board.fmpp -O $(BOARDDIR)/

.PHONY: CLEAN_RULE_HOOK
CLEAN_RULE_HOOK:
   @echo CLEAN_RULE_HOOK
   @echo - $(BOARDDIR)/{board.h board.c board.mk}
   @rm -f $(BOARDDIR)/board.c $(BOARDDIR)/board.h $(BOARDDIR)/board.mk 2>/dev/null
