Re: [Bacnet-developers] Having problem porting STM32F4xx

Hello Emre Can Kirtorun,

I’m interesting on your topic because we are going to do some development at STMF4XX.
What kind of IDE are you using? We are using TruStudio?

Regards
Samuel

Hello Emre Can Kirtorun,

You didn't mention which compiler or IDE you are using, so I'm guessing you are not using the example code in ports/stm32f4xx folder as-is.
The IAR project file uses some defines to tune RAM usage, and there are more settings in src/bacnet/config.h<https://secure-web.cisco.com/1Vi-kbgMGKXvURH93t7UKoQayae7bFRSUnyxWPaYZHsPCLKfQulrneOhBqDRf9kNYcLCEYlJlU78IgCD6tFmn4OkknDu2u28oS2CNEE50lmCHSB1NAjqTLKlnolN3MelT2bP1bPnC7_kQ6IM3QSZY0NYf5jAXhqCIwOTBxBRqU3MVu57CsorjearB71-CibjnhBB0OVhq6KJFq2uv9bbnnyPYaZunSPwY6gzRCzvbtukdRLKSwEa9M_AXXzJecSqAr9taJHQge6GjIK9bn_3Qvuyf0AtdwY6UXoKZWxqj_b9W-O6UzL8iUE9_NywtvgTw/https%3A%2F%2Fsourceforge.net%2Fp%2Fbacnet%2Fsrc%2Fci%2Fmaster%2Ftree%2Fsrc%2Fbacnet%2Fconfig.h> file that can be overridden from their defaults, or just make your own config file.

IAR:
                    <state>NDEBUG</state>
                    <state>USE_STDPERIPH_DRIVER</state>
                    <state>STM32F4XX</state>
                    <state>BACDL_MSTP</state>
                    <state>MAX_APDU=480</state>
                    <state>BIG_ENDIAN=0</state>
                    <state>MAX_TSM_TRANSACTIONS=1</state>

GCC Makefile:

BACNET_FLAGS = -DBACDL_MSTP=1
BACNET_FLAGS += -DBACAPP_ALL
BACNET_FLAGS += -DMAX_APDU=480
BACNET_FLAGS += -DBIG_ENDIAN=0
BACNET_FLAGS += -DMAX_TSM_TRANSACTIONS=0
BACNET_FLAGS += -DMAX_CHARACTER_STRING_BYTES=64
BACNET_FLAGS += -DMAX_OCTET_STRING_BYTES=64
# if called from root Makefile, PRINT was already defined
BACNET_FLAGS += -UPRINT_ENABLED
BACNET_FLAGS += -DPRINT_ENABLED=0

Probably MAX_TSM_TRANSACTIONS needs to be lowered, since the default is 255.

Best regards,

Steve

Hello everyone,

I've been trying to port stm32f4xx on my smt32f4 device and when I try to compile the whole bacnet stack I receive a RAM error which says RAM overflow . I have no idea  about where I made a mistake but any help would be appreciated.

Best regards.
