Possible bug in RTC clock handling logic
Posted: Mon Apr 13, 2015 9:15 pm
Hi, STM32L1xx project using Chibi-2.6.7.
I am creating a custom board.mk/c/h for my own hardware, starting with the STM32L-DISCOVERY as a template. My board does not use external oscillators, so I have the following in mcuconf.h
That works fine, but then in my board.h, I've changed the following:
But when I compile I get:
Which makes me think it is ignoring my choice of STM32_RTCSEL. It does the same, if I set it to STM32_RTCSEL_LSI
Any ideas?
I am creating a custom board.mk/c/h for my own hardware, starting with the STM32L-DISCOVERY as a template. My board does not use external oscillators, so I have the following in mcuconf.h
Code: Select all
#define STM32_HSI_ENABLED TRUE
#define STM32_LSI_ENABLED TRUE
#define STM32_HSE_ENABLED FALSE
#define STM32_LSE_ENABLED FALSE
...
#define STM32_RTCSEL STM32_RTCSEL_NOCLOCK
That works fine, but then in my board.h, I've changed the following:

#if !defined(STM32_LSECLK)
#define STM32_LSECLK 0
#endif
#if !defined(STM32_HSECLK)
#define STM32_HSECLK 0
#endif
