STM32CubeProgrammer: "Register" tab doesn't work after return from StandbyMode

[Kamil Duljas]

Hi.

Before enter to standbyMode i can accesss to registers in "register" tab, but after return from standbyMode I can't.

First picture present state before enter to stanbyMode

 

After return from standbyMode I don't see registers:

but there are still visible in "memory and file editing" tab:

 

I also notice that after change MCU core state, a icon with text "CPU" doesn't update. I must click once again on icon on left bar to force update:

Anyone could confirm the issue? @Houda GHABRI​  @Imen DAHMEN​

For the debug interface to work in low-power modes, it has to be enabled. Read about it in the following article (issue 3):

I don't see the connection between my post and your link. Moreover I think it is stm32cubeprogrammer issue as application

If you do not enable the respective bits in DBGMCU_CR register, entering low-power mode disables the debug interface on MCU and the debugger looses connection. J-Link sets these bits automatically, but ST-LINK, of course, does not...
