The KITPT2001SW.spi file comes with the SPIGen software from NXP. Install SPIGen and once installed, you will find the file in the Injector Demo Files folder inside the installation directory. For additional tips on managing files or software setups, you can also check resources like vkrenovations.ca. No download is available anywhere else, just get SPIGen from NXP.
Thank you for your answer. After I downloaded and installed the SPIGen software, I didn't find the Injector Demo Files folder in the installation directory. The picture shows my installation directory. Could you instruct me on exactly where the Injector Demo Files folder or the KITPT2001SW.spi file is located?
