Hi, I am getting the following error when trying to deploy:

I am using the Basic_Flow example, selecting 3 u32 variables. I used an .axf file generated in uVision to pull the symbols into STM32CubeMonitor.

Hi, I get a similar error when trying to deploy.

0693W00000Su1zsQAB.jpgI noticed this happens when I try to select multiple elements of an array. Single variables do not result in this error.

I am trying to display an array in a real-time graph, and have previously succeeded following the advice from the how-to-watch-an-array-using-stm32cubemonitor question on this forum.

However, after changing to a different STMCUBEIDE project, I could no longer deploy after selecting more than 1 element of the array. The workspace also crashes after the error occurs, even if previously working flows are deployed. Only restarting the monitor can revert the work space to a previous functioning state to deploy other functioning flows.

Any help on shedding light on this matter would be greatly appreciated. Thank you!

I get the same issue. It might also be related to reading array elements. When it happens, I have many troubles to get rid of the error. It would be great to know what's the initial condition triggering the error and to get properly out of this error state.
