Hi!

I have three Nucleo-L152RE Board with this features:- Board 1 and Board 2:  STM32L152RET6GH23W, Hardware version: MB1136 C-02- Board 3: STM32L152RET6GH245, Hardware version: MB1136 C-03I made a program that use RTC to wake up the system from Stop Mode every 10 sec.I use LSI as RTC clock source. And HSI as System Clock Source.The program works only with the Board 3. How this is possible?What's the difference between board with different Hardware version and micro with the last 5 number different? I use System Workbench and Windows

I'd suggest looking at DBGMCU_IDCODE, I remember at least one significant chip change in the L1 family. Check also solder bridges

The problem was that the board had a different version of STLINK firmware. I upgraded and solved the issue.
