MBR lost ?

Hello,

I am developping an application using Softdevice which works (or worked).

Then, as I also need using UART, I built and flashed the example program nRF5_SDK_15.3.0_59ac345\examples\peripheral\serial

This too worked correctly.

Same thing with nRF5_SDK_15.3.0_59ac345\examples\peripheral\serial_uartes

But when I reflashed Softdevice then my program, it started sending flows of data to the UART then stopped.

Same result each time, even after erasing the whole flash and reflashing softdevice and my program.

The serial program still works fine if I flash it.

As the serial program is loaded at address 0, I am wondering if it did not erase something essential for softdevice, like the MBR.

And, if yes, how to recover?

Best regards
