I have a problem with a couple of BLUENRG-M2SP modules. I tried flashing the firmware under linux (We have to flash 100+ devices and each device needs a different firmware so plug and play flashing is not sufficient enough, so I copied ST's config from the flasher utility) and the operation failed with the following error message: 'Error: Erase command failed (timeout)'. So I tried flashing with ST's BlueNRG-X Flasher Utility 4.1.0 But I got the same error.
Here are some logs:

When I try to read the content of the flash than it's all 0xff (I guess the erase did this).
Is it possible to unbrick these devices?
