STM32CubeIDE 1.19.0 live expression fail

[Zzaaack]

Hi everyone,

STM32CubeIDE v 1.19.0

MCU: stm32h755

I am debugging correctly the dueal core by means i see all registers in the live expression changing values without my intervention as expected by the simple code i wrote. As soon as i input a value, let's say I change the value of a variable from 0 to 1, then the panel shows:

I used to work with the 1.13.2 version and older fw package and never had this issue, with the very same MCU, but with the new fw package and new IDE this is what i get.

I must say that to make it work in the first place I had to force the gcc toolchain using the command "gcc -gdwarf-4" in project settings. There is for sure a link but i can't get the hang of it.

Thanks in advance to all.

For the sake of understanding, i setup the debug config as explained in stm AN:

Hello @Zzaaack 

Thank you for your contribution!
Actually, the CubeIDE team is aware of this issue and it has been reported internally for fix (Ticket number 215220 is only for reference, not available outside of ST.)

KR,

Thanks for the prompt answer.

Do you recommend a workaround?
I need to decide if to stick with this IDE version or switch to a previous one.

I wanted to add a consideration, I am using a st-link, not SEGGER devices, if this is the ticket you are referring about, it is incomplete.

This is a reference from

that was updated last week, maybe it is not up to date.
