Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
The FSBL → Application jump is working fine, and the application is running properly from external flash.However, I am facing the following issues:Ethernet IssueEthernet initialization is successfulPHY link is UP, but speed is 10 Mbps (Full Duplex)Pi...
Hi all !I'm trying to write a driver for a LevelX system to talk to a QSPI chip over the OCTOSPI1 peripheral (STM32H563). I got the chip to respond to most commands, set it up in reading / protected mode.But, later, I've spotted an issue : I cannot s...
HelloI have my own board with STM32G071KBT6 microcontroller. I successfully comunicate with charger by PD protocol and I receive up to 21 V (PPS). But I need above 21V. I have power bank with AVS up to 28V and USB cable with e-marker (up to 240W). Ho...
Hi everyone, I’d like to ask for your expertise. I’m working with a custom board based on the STM32H755ZIT, configured in LDO mode. My issue is that when I connect the board to my PC via USB to use the Virtual COM Port (VCP), the computer does not de...
Hi,How do I serve request Get Source Capabilities Extended? I'm using STM32G0B1 with a port configured as SRC.When a SINK sends the Get Source Capabilities Extended the STM PD library responds with 'Not Supported' and my code is not aware that this e...
Hello all,There might be a possible bug in HAL_UART_DeInit(). When calling HAL_UART_DeInit() when it is already initialized could lead to CPU starvation. Assume that an interrupt fires after calling __HAL_UART_DISABLE(huart); and before huart->Instan...
is there a template for developing a custom bootloader that uses the lpuart?Has the application firmware the ability to trigger a bootloader state so I can upload the new application firmware into stm32g051g8?What are the changes that I have to do on...
I’m working on STM32F405RGT6, receiving audio from ICS43432 (MSB First, 24bit on 32 bit frame).sing Circular DMA (double buffering) to read it in. After 3 days of debugging and millions of mem corruptions and stackoverflows later I finally managed to...
Hi tech supoort reps, According to the documentation for the NUCLEO-563ZI (MB1404C), the board is expected to support I3C mode. However, during our evaluation, we were unable to successfully issue I3C shell and CCC (Common Command Code) commands.At ...
SDMMC HAL driver implementation is full of timeouts like this:uint32_t count = SDMMC_CMDTIMEOUT * (SystemCoreClock / 8U / 1000U); do { if (count-- == 0U) { return SDMMC_ERROR_TIMEOUT; } sta_reg = SDMMCx->STA; } while (SOME_FLAG_NOT_SET);I...
