## Summary Set SDMMC_CK pin to high speed (50 MHz) mode. When it was in slow speed mode (by default), the output SDMMC_CK clock rise and fall times were about 13 ns each, that were very slow and prevented some SDIO devices from working. Moreover, SDMMC D[7:0] and CMD pins were already in high speed (50 MHz) mode rather than SDMMC_CK pin. And now the I/O SDMMC speed configuration is the same as it already was for STM32F2/F4/F7 (50 MHz). ## Impact STM32H7 SDMMC ## Testing -- This is an automated message from the Apache Git Service.
