MASS ERASING A DEVICE NOT RESPONDING TO SWD COMMANDS

The SWD debug tools can only communicate with the
microcontroller when the device is in active mode.
Similarly, watchdog or software resets that occur when a debug
session starts cause the debug session to end with errors.
To recover a device that is locked in this way, mass erase the
user flash.

To mass erase the user flash, take the following steps:
1. Hold the S3 button down to place the device in boot mode.
2. While holding the S3 button down, press and release the
reset button (S1) to lock the device in a loop in the kernel
space so that the device does not execute user code.
3. In the IAR Embedded Workbench, navigate to Project >
Download > Erase memory (see Figure 39).
4. The window shown in Figure 40 opens. Click OK.
