Backup SRAM

Looking to use backup SRAM, on F4 device, the hal_lld.c as a #if STM32_BKPRAM_ENABLE, but this is not defined anywhere, i would have thought it would be in the mcuconf.h ???
Anyways i added
#define STM32_BKPRAM_ENABLE TRUE
to my mcuconf.h and it now errors on
undefined reference to `rccEnableBKPSRAM'
????

got a feeling this is down to me using 2.6.1 which is package with chibistudio, where as 2.6.3 will not have this issue ?

Update to 2.6.3 by just replacing the chibios folder. That function is defined in 2.6.3.

I did this
but you then get lots of errors in the hal_lld.h and this come back to this in stm32.h error is "STM32 device not specified"
#if defined(STM32F030) || defined(STM32F0XX_LD) || \
defined(STM32F0XX_MD)
#include "stm32f0xx.h"
#elif defined(STM32F10X_LD_VL) || defined(STM32F10X_MD_VL) || \
defined(STM32F10X_HD_VL) || defined(STM32F10X_LD) || \
defined(STM32F10X_MD) || defined(STM32F10X_HD) || \
defined(STM32F10X_XL) || defined(STM32F10X_CL) || \

#include "stm32f10x.h"
#elif defined(STM32F2XX)
#include "stm32f2xx.h"
#elif defined(STM32F30X)
#include "stm32f30x.h"
#elif defined(STM32F37X)
#include "stm32f37x.h"
#elif defined(STM32F401xx) || defined(STM32F40_41xxx) || \

#include "stm32f4xx.h"
#elif defined(STM32L1XX_MD)
#include "stm32l1xx.h"
#else
#error "STM32 device not specified"
#endif
It seems to me all these have been changed from 2.6.1 to 2.6.3 ??

Is the device identifier correct in board.h? the new ST header requires different identifiers.

the board identifier is
#define STM32F4XX
which i ok for the older 2.6.1 stm32.h see below
#if defined(STM32F0XX)
#include "stm32f0xx.h"
#elif defined(STM32F10X_LD_VL) || defined(STM32F10X_MD_VL) || \
defined(STM32F10X_HD_VL) || defined(STM32F10X_LD) || \
defined(STM32F10X_MD) || defined(STM32F10X_HD) || \
defined(STM32F10X_XL) || defined(STM32F10X_CL) || \
defined(__DOXYGEN__)
#include "stm32f10x.h"
#elif defined(STM32F2XX)
#include "stm32f2xx.h"
#elif defined(STM32F30X)
#include "stm32f30x.h"
#elif defined(STM32F37X)
#include "stm32f37x.h"
#elif defined(STM32F4XX)
#include "stm32f4xx.h"
#elif defined(STM32L1XX_MD)
#include "stm32l1xx.h"
#else
#error "STM32 device not specified"
#endif
but as stated this as changed, so should my board identifier now be ?
#define STM32F40_41xxx
If so do i still also keep #define STM32F4XX ??? as there is alot of code in 2.6.3 that still uses the old identifier i.e. look in sdc_lld.h at SDIO Clock divider ?

You should use:
STM32F40_41xxx
In hal_lld.h there is:
Code: Select all
#if defined(STM32F429_439xx) || defined(__DOXYGEN__)
#define PLATFORM_NAME "STM32F429/F439 High Performance with DSP and FPU"
#define STM32F4XX
#elif defined(STM32F427_437xx)
#define PLATFORM_NAME "STM32F427/F437 High Performance with DSP and FPU"
#define STM32F4XX
#elif defined(STM32F40_41xxx)
#define PLATFORM_NAME "STM32F407/F417 High Performance with DSP and FPU"
#define STM32F4XX
#elif defined(STM32F401xx)
#define PLATFORM_NAME "STM32F401 High Performance with DSP and FPU"
#define STM32F4XX
#elif defined(STM32F2XX)
#define PLATFORM_NAME "STM32F2xx High Performance"
#else
#error "STM32F2xx/F4xx device not specified"
#endif
This way the drivers don't have to check for all those identifiers.

needed to freashen the indexing also
