KW45 SPSDK burns NBU and locks up

[Melton]

Dear Sir，

  I encountered a problem that the chip locked after burning NBU through SPSDK.

1. chip type: KW45B41Z83A.

2. I downloaded the latest AN13883SW from the official website.

3. I followed this link to run SPSDK, then also successfully burned key and SB3 files.

KW45xx and K32W1xx Load NBU image — SPSDK documentation

4. Finally I burned the KW45 wireless uart routine,However, it does not work, and other mcu-related routines can run normally,similar to hello world routines, my board works fine.(SDK version:V2.12.5)

5.  Then I tried to update the SB3 file generated by SPSDK to the SB3 file within the SDK(version 2.12.5) via blhost,but they refused to burn it,errors in the following picture.

6. I can only burn the SB3 file generated by SPSDK through BLHOST, as shown below, but this SB3 file can not run the radio frequency routine.

So I would like to ask you what causes this,looking forward to your reply,thank you!
