I am having problem with FATFS remounting with Cube IDE and STM327H50. Tracing the program surfaced the SD_initialize() function which is defined in the ST library file FATFS/Target/sd_diskio.c. The problem is that when BSP_SD_Init() failed, SD_ini...

Is the schematic of the NUCLEO-G070RB available? If so, where?I am looking for a reference schematic for SMT32G070xx, preferably SMT32G070CB.

Hi everybody,I am using STM32F401CE and would like to use DMA to output a block of bytes using a 8 bit output port and a 'write' strobe output. That is, 8 output pins + 1 strobe output for the strobe pulse, per the timing diagram of the ILI9341 TFT s...

Hi all,I am new here and to STM32 in general.Does the STm32F401CE comes from the factory with a DFU bootloader?If so, does a full chip erase with the CubeProgrammer and a stlink v2 erases that factory bootloader?.If so, is the binary of the factory b...

I am trying to understand the example below. Since HAL_UARTEx_RxEventCallback is called also on full complete, is it possible that Size < old_pos? That is, is it possible that a single call to HAL_UARTEx_RxEventCallback will cover a buffer wrap aro...

Thanks Tesla.

What if I will use timer(s), can this work? E.g. a timer that generates both the strobe output and the DMA per byte trigger? Can this achieve a transfer rate of let's say 10M bytes/sec on a 84Mhz STM32F401CE?Can the DMA update Port A bits 0 to 7 wi...

Thanks for the answer.I am not familiar with FSMC and a quick search in the STM32F401CE's datasheet for 'FSMC' provides no hit.Can you point me in the right direction?

Thanks MM..1, that answers my question, factory bootloaders cannot be erased.BTW, I looked that the document you mentioned before I posted here but I still see where it says that factory bootloaders cannot be erased.

Wrong returned value in the library function SD_initialize()?

Where is the schematic of the NUCLEO-G070RB board?

Can DMA output a byte stream with 8080 style 'write' strobe?
