UNIFLASH: Cortex-M not entering SACI after pin reset

Tool/software:

Hello,

I'd like to know possible methods for restoring a device flash after using the chip erase function.

On Uniflash I receive the following error when trying to load a .bin file:

File Loader: Memory write failed: Target did not enter SACI after pin reset

What could be causing this and how could I restore the flash capabilities of the part?

Thanks in advance
