Hello,
I am using an STM32F103RB MCU in a specific Hardware design.
The Hardware was always working fine until I flashed a software which implements the stop mode (deep sleep mode) management (it's a low power mode supported by ST by setting the SLEEPDEEP bit in the System control register (SCB_SCR) supported by ARM).
In the Software after calling the set instruction WFI (wait for interrupt) to wait for an interrupt to wake-up the micro-controller, it still sleeping for ever.
In debug session (using j-link as debugger via SWD) by pressing next step in IAR, I can go out from deep sleep mode.
When I go out from debug session I can't connect anymore to the micro-controller and I can't flash it anymore.
I have the issue as described in the screenshot.
I am really stick with this and I look forward your help !
Best regards,

Of course you can!
You should always do that when cross-posting the same question to multiple forums.
