64bit time_t issue in RTCv1 section Topic is solved
Posted: Tue Aug 07, 2018 8:17 pm
Hi,
just switching my toolchain host from Win10 to Debian i had an issue with HAL 6.0.1 and STM32F103 mcu. I used the actual toolchain GNU MCU Eclipse ARM Embedded GCC which surprised me with 64-bit time_t type.
The function call localtime_r failed.
I solved that with a small patch in hal_rtc_ldd.c.
Maybe there exists a better solution?
