Mass erase doesn't work

05-Jun-2024

When trying to perform a mass erase of the chip, you get an error, e.g.  UMI error. For mass erase to work, the CPU should be stopped. In case you have a multi-core device, the non-primary cores should be stopped as well.


Possible solutions

Enable the Allow mass erase option

Enable this option via the Hardware | <device> | Configure Device dialog.


Disable memory protection

Follow how-to guide Disabling Flash Protection.


Make sure that all the CPU cores are stopped when trying to perform mass erase.

Open View | Debug | Session Explorer and check the status of CPU cores.
