Hi @yr1205 ,
What version of the MBDT for S32K3 toolbox are you using?
I do recommend you install the latest NXP Model-Based Design Toolbox for S32K3 version 1.7.0 - Product Release Announcement - NXP Communit...
Second , what board are you using?
If you are using the MCSPTE1AK344 kit, i recommend you follow the Getting started guide
Third, you are using the s32k344_mcb_sensorless_s32ct.mdl ?
If the Blue LED doesn't turn On, there might be a problem with the GD3000 board , not fully inserted into the S32K344-T172 board.
To fix this, you need to press on the GD3000 headers to get better contact into S32K344-T172 board.
Best regards,
Stefan V.
