DEV_TARGET_NOT_HALTED

[amine1]

I have a problem with this part of the code that involves the HAL erase function. I want to calculate the sector address from the block number i, but after execution, I encounter an error during debugging: "target ST-LINK error (DEV_TARGET_NOT_HALTED)."  any one can you give me a solution please

Hello @amine1 and welcome to the Community :),

Could you please give more detail about the issue.

Which STM32 MCU are you using?

Are you use an ST board?

Thank you.
