Hello,

Thank you for very fast response!

These modifications helped and know I'm able to use SDK v2.9.0 with sysbuild.

Hello,

Sysbuild automatically enables the Partition Manager to manage the device memory layout. The problem is that places the settings storage partition used for storing BLE bonding information at the end of the flash. This overlaps with the pre-programmed bootloader. The solution is to create a static partition for the Partition Manager to reserve this area as I've done in the modified version of the project below.

Modified peripheral_uart sample (SDK v2.9.0)
