When I follow this tutorial and build the secure BLE bootloader example, I got this error:
cannot find ../../../../../external/nrf_oberon/lib/cortex-m4/soft-float/liboberon_3.0.5.a: No such file or directory
Then, I went to the above directory. I found that I only have liboberob_3.0.6.a (different version). What should I change, please?

Thanks in advance!
