ChibiOS Free Embedded RTOS

one thing what i can imagine of this issue is a delay in DMA, if MDMA is dedicated for SPI any you using other one there is a "gap" in data, from other hand, maybe there is other clocking for SPI and DMA and then you increse clocking the "gaps" dissapered

are you using DMA for SPI ? maybe try to disable it just for test

bump

Hi again I found a typos in hal_lld.h i H7 libraries. First: * @brief SPI6 clock. */ #define STM32_SPI6CLK STM32_PCLK4 #elif STM32_SPI6SEL == STM32_SPI6SEL_PLL2_P_CK #define STM32_SPI6CLK STM32_PLL2_P_CK line 2582 and 2583 should be: #elif STM32_SPI6SEL == STM32_SPI6SEL_PLL2_Q_CK #define STM32_SPI6C...

Thanks for update. Good job.
Any plans for SDMMC driver ?
