Hi all, I am trying to read and write the sd card using OTG(in MSC mode) from PC . I am using the STM32f4-disc board . My sd card is working properly which is 16 GB micro SD-HC . I followed the video which is given link below. And I followed a forum ...

I am using STM32F407VG board for logging the data continuously using FATFS. When I am writing the data it is working fine some time , then suddenly it is giving f_write or f_sync error . After that error It is not able to write and it is stopped ...

I am using STM32F407VG. I am transmitting data from PC to STM32 using uart. I wrote the code to receive 100 bytes. Firstly I call the HAL_UART_Receive_DMA more than once and then I sent the data from PC to STM32.I observed it receives only 100 byte...

I want to use FIFO without Enabling USART_DMA in STM32CubeIDE . Is this is possible? If possible I can differentiate the small delays between data. and I can process the data according my requirement.

Hello,Am using STM32F407 (Discovery board). This is connected with a PC which is sending 100 bytes of data and realized that only 1 byte is received and remaining 99 bytes are lost. Below is the code excerpt running on STM32F407   ret = HAL_UART_...
