Summary: Changing stm32 wallclock RTC clock source does not

Product: eCos
Version: unknown

OS/Version: Cortex-M
Status: UNCONFIRMED
Severity: major
Priority: low
Component: Wallclock

stm32 wallclock driver bugfix
I wanted to change from using LSI as RTC clock source to using HSE/128 as RTC
clock source.
For this I change the eCos configuration CYGHWR_DEVS_WALLCLOCK_STM32_RTC_SOURCE
from "LSI" to "HSE_128" and rebuilt the eCos library.
But I found out that this change was not successful because of two bugs in the
stm32 wallclock driver (stm32_wallclock.cxx)
Bug 1: "Disable backup domain protection" is currently done after "Reset backup
domain"
Bug 2: In case of the "HSE_128", backup domain needs to remain write enabled
(i.e. backup domain protection disabled)
I corrected the bug for my environment and here I attach a diff file with a
bugfix for the stm32 wallclock driver.
