Hi,
The User Guide is provided once the LLCE package is installed. It should be located on the following address:
"C:/nxp/S32G_LLCE_1_0_4/firmware/llce_interface/doc/LLCE_firmware_user_guide.pdf"
It may vary depending on where you installed it, but it is given after the installation. The Reference Manual also provides information regarding LLCE [Chapter 54, Page 2450, S32G2 Reference Manual, Rev. 6, 11/2022].
Please, let us know if this information was helpful or not.
