STM32G070RB, Maximum Alarm length

What is the maximum alarm length in the G070. I only see about 30days.I need 6 months.I guess I could implement one using the TAMP_BKPxR registers and compare the RTC DR , TR with the alarm values I have store in the TAMP regs. ( stripping out the W...

Do multiple HAL_RCCEx_PeriphCLKConfig() calls overwrite each other?

Hi i'm trying to configure two parts the SDMMC and the SAI. Both are initialized seperate from each other in my design, before i put them together, can i just run both configurations seperately?

STM32H743 Nucleo board SEGGER JLink issue

Hi There, I bought two STM32H743 Nucleo boards recently and did some tests on them. As usual, I first converted ST-Link v2 to JLink interface using the tool SEGGER provided. I have done this with F1, F4, and F7 series boards in order to use JLink RTT...

Does the STM32 still read the BOOT0 pin when protection level 2 is enabled?

If I enable read out protection level 2, does the MCU still read the BOOT0 pin at start and update the SYSCFG_MEMRMP bit BOOT_MODE?I'm writing my own bootloader and It would be nice to still be able to get the BOOT0 pin level at start.
