thanks for the explanation :-) Set the Device Type and Revision with nrfjprog works fine :-) The Sofdevice Version is set automatically.

Hallo Frederic,

Device type and device revision is stored at DFU_DEVICE_INFO_BASE address in UICR, please have a look at dfu_init.h. The default value of the device info in UICR are 0xFFFF as defined with DFU_DEVICE_TYPE_EMPTY and DFU_DEVICE_REVISION_EMPTY. Yes, you can flash application with any revision and type if they are 0xFFFF in UICR.
No, the bootloader won't write them after application has been programmed. You would need to write the value of DFU_DEVICE_INFO either manualy using nrfjprog/J-link commander, or implement that in the bootloader code, similar to how we write BOOTLOADER_REGION_START to NRF_UICR_BOOT_START_ADDRESS in bootloader_settings_arm.c
Yes, you would need to do it yourself as in #2.
