ceaafc2019 arch/arm/src/stm32: Fix scope of naming. CONFIG_RTC_LSECLOCK->CONFIG_STM32_RTC_LSECLOCK, for example. Fix some usage. Although CONFIG_STM32L4_RTC_xxxCLOCK was defined in the Kconfig, CONFIG_RTX_xxxCLOCK was used in numerous places in the code 2018-06-28 15:58:08 -06:00

9b11187b2a STM32 OTG HS: A little research reveals that only the F2 RCC initialization set the OTGHSULPIEN bit and Photon is the only F2 board configuration that uses OTG . Therefore, we can simplify the conditional logic of the last PR. Negative logic was used (#ifndef BOARD_DISABLE_USBOTG_HSULPI) to prevent bad settings in other configurations. But give these facts, the preferred positive logic now makes more sense (#ifdef BOARD_ENABLE_USBOTG_HSULPI). 2017-03-11 18:00:38 -06:00

e0f7b9582a STM32: Review of last STM32 F2 PR. Progate changes to STM32 F4 and F7 OTGHS. Rename some configs/photon/src files. Naming can be either photon_ or stm32_ but must be consistent. 2017-03-11 16:31:11 -06:00

f073092fad 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.

7b89f64b37 stm32-rtc: Add support for the internal low speed clock (LSI) 
Some boards do not have the external 32khz oscillator installed, for those boards we must fallback to the crummy to the crummy internal RC clock.  Turn on by defining CONFIG_RTC_LSICLOCK.
