From Kristopher Tate (2015-030-29). * arch/arm/src/armv7-m: Add configuration option and logic to support the D-Cache in write-through mode (2015-03-29). - + * arch/arm/src/stm32/Kconfig, stm32_lse.c, stm32_lsi.c, stm32_rtc.c/.h, + stm32_rtcc.c, stm32_rtcounter.c, and stm32f*_rcc.c: The + STM32F4Discovery board doesn't come with a Low speed external + oscillator so the default LSE source for the RTC doesn't work. In + stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI. + The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call + that rightfully enables the lsi clock; but the next times, when the + rtc is already setup, the rtc_resume() call does NOT start the lsi + clock! The right place to put LSE/LSI initialisation is inside + stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked + the possible uses of the LSI and the LSE sources: the LSI can be used + for RTC and/or the IWDG, while the LSE only for the RTC (and to output + the MCO1 pin). This change is not verifed for any other platforms. + From Leo Aloe3132 |
