FreeMarker template error when generating code with CubeMX and enabling SDMMC2 with FATFS

Question

This can be reproduced by starting a new CubeMX project using reference MCU STM32L4P5ZGTx and firmware package STM32Cube FW_L4 V1.17.0. Start by enabling SDMMC2 (4 bit wide bus mode) and FATFS (SD card mode with SDMMC instance set to SDMMC2, any GPIO pin will do for platform setting). Anyone have an idea for a work around or if this will be fixed on CubeMX? I'm attaching my .ioc for completeness.

Hello @RMora.4​ ,Thanks for your feedback,You are right, the FreeMarker template error should not be occurred when SDMMC2 is used with FatFS. For the time being, you can avoid this error by using SDMMC1 instead of SDMMC2 with FatFS or you can just enable SDMMC1 and keep using SDMMC2.I have raised this issue internally to be fixed as soon as possible. I'll keep you posted with the updates.Sorry for any inconvenience that this may cause.If you issue is solved, please close this post by clicking the "Select as Best" button.
