The example with FileX on STM32H735G-DK is not working with exFAT SD cards.

[Freistyle]

I tried using the example Fx_uSD_File_Edit for the discovery kit: STM32H735G which works fine.

But when changing the configuration in .ioc file to exFAT instead of FAT and using an SD card formated in standard exFAT the example goes into an error. The error comes in the following function: SDMMC_GetCmdResp1(). The first do while loop is returning an SDMMC_ERROR_TIMEOUT.

The problem is that I need exFAT to store a big amount of data (>32GB) and FAT don't fit.

Thank you very much for your help.
