Hi@PedroCao
1.The IDE and SDK of S32K1 are provided to users free of charge, the only thing you need to worry about is to purchase a suitable debugger. Commonly used debuggers are recommended: PE, J-LINK and Lauterbach.
2.There are not many customers using UAD2pro, but I think it supports S32K1. For details, you need to confirm with UAD2pro's technical support.
3.For IDE I recommend users to install two versions
1. S32 Design Studio for Arm 2018 or V2.2.
Although these two versions are very old, many released demos are based on this version.
2.S32 Design Studio Platform V3.5,
the latest platform, can install RTD driver for MCAL requirement.
