I have been playing around with the FRDM-MCXW71 board recently and I encountered some uncertainties while trying to set up the NBU firmware.
I followed through this guide for it and what I noticed is that it's quite old. My confusion is specifically regarding the .sb3 files that are in the SDK used for flashing the firmware. In the guide, said file is named differently, it is just mcxw71_nbu_ble_1_9_14_1.sb3
When I went digging in the SDK for this file, I found 3 different files going by:
- mcxw71_nbu_ble_hadm_hosted.sb3
- mcxw71_nbu_ble_hosted.sb3
- mcxw71_nbu_ble_xp_hosted.sb3
There is also a .xip file with the same name for each one of these. I tried looking around to find any explanation about the difference between these but I couldn't find any. Furthermore, I tried running the bm beacon example with each firmware file and it only worked with mcxw71_nbu_ble_hadm_hosted.sb3
Thanks in advance for reading and answering
