MCU: stm32F411cEu6
OS: Chibios RT 19.1.2
File: ChibiOS_19.1.2\os\hal\ports\STM32\STM32F4xx\stm32_rcc.h
Row: 432
Code: #define rccEnableBKPSRAM(lp) rccEnableAHB1(RCC_AHB1ENR_BKPSRAMEN, lp)

Datasheet shows no RCC_AHB1ENR_BKPSRAMEN bit in register RCC_AHB1ENR.

Fix suggestion:

#ifdef RCC_AHB1ENR_BKPSRAMEN
#define rccEnableBKPSRAM(lp) rccEnableAHB1(RCC_AHB1ENR_BKPSRAMEN, lp)
#endif

Hi,

I committed a slightly different fix.

Fixed as bug #1029.
