Hello everyone,Our custom board use STM32H750 + USB3320 as USB MSC Device.Code reference MSC example and use st library except board specific part.Some pcs of the custom board have USB packet timeout problem when copy lots of files.I have no idea wha...
SWAP_BANK for the STM32L552 is a bit in the eeprom, but we want to swap the flash banks in an own bootloader dynamically and do not want to expire the eeprom's lifetime,Any option to swap the memory without eeprom settings?
I am using a custom board which includes a uSD that is interfaced to a STM32F765 through the SDMMC1 pins. The clock rate is set to 48 MHz. I am using the stm32f7xx_hal_sd driver to read and write to an uSD card. I initialize the driver with a call t...
Hi,In a matter of days, I'll have to port a user bootloader from STM32F303 to a STM32G473 mcu.The question is about the Dual Bank feature of G473: since Dual Bank is active by default (DBANK=1), I'd prefer to NOT switch to Single Bank (as it is neces...
I want to use hardware I2C (which is only available on pins PA9, PA10 on the STM32F030F4P6 in TSSOP20 case). That overlaps with the standard pins used in the bootloader code for USART1_TX and USART1_RX (AN2606 Rev 55, page 50). The alternative pins u...
Greetings to the ST community,I was using the example project provided by ST in "STM32F769I-Discovery\Applications\Audio\Audio_playback_and_record\EWARM" and found out that voice was being output through the headphones. However I connected speakers t...
I'm trying to use fileX for format a card with filex with exfat but having some issues, after the format when I create a file the file says it is already created, presumably from a previous format, possibly with regular FAT.Currently calling as stat...
This line:ProtocolStatus->Activity = (StatusReg & FDCAN_PSR_ACT);I think it should be:ProtocolStatus->Activity = ((StatusReg & FDCAN_PSR_ACT) >> FDCAN_PSR_ACT_Pos);I'd appreciate if ST can confirm this.
How to resolve recvfrom() issue on STM32_Network_Library. I'm using stm32H7B3I-DK board.FreeRTOSSTM32_Network_LibraryES_WIFI (BSP) When I tested UDP socket, sendto() was working.But recvfrom() was not working, it was blocked for ES_WIFI_MAX_SO_TIMEOU...
Hello community, I experienced a strange behavior, when when using the UART-DMA-mechanism.The MCU is a STM32L051R6T6, and I use CubeIDE with HAL-drivers.I receive a cyclic telegram of 40 bytes on both USARTs.The telegram starts with two detection byt...
