Hello,I use SM32F103ZH6 MCU.I'm trying to send log (i.e. text) messages from my board to host PC on a UART2 using HAL_UART_Transmit_DMAproblem: 2 successive calls to HAL_UART_Transmit_DMA, only last call gets executed.logging function (sends text to ...
Dear community,i have developed a custom board for ETH using STM32F407VGT6 and LAN8742. In this I have used one of gpio for resetting Phy IC. but my board is not working when controller is in Run mode. Some times it fetches IP when controller is in b...
Hi everyone!I’m developing a bootloader for a STM32L476RG MCU. My actual boot works fine (it erases my flash area before start writing the new application). However, if something wrong happens in the middle of an upgrade, it’s not possible return for...
Hi All,I am currently designing a few products and would like the ability to update firmware at a later date should it be required. CAN is most appropriate for our situation. I have not needed to deal with the bootloader in the past, so I'd just like...
Hello!I am connecting my nucleo to my computer through the user usb. I have set FDMOD and received the USBRST message and initialized the endpoint, but after i receive ENUMDNE I never receive the RXFLVL interrupt.Here is the output of dmesg on my com...
When trying to read/write to the connected eMMC device, the eMMC driver will sometimes fail with an error. After failing in this way, every call to HAL_MMC_ReadBlocks or HAL_MMC_WriteBlocks will fail until the microcontroller is restarted. If the fir...
Hi,I have been reading through documentation for the ST UART bootloader on the STM32F091cc chip. I want to use UART2 as my UART for both standard serial communication and FW updates.UART2 can use pins (PA2,PA3) or (PA14, PA15). I would like to be abl...
hello allcurrently i am working on Free RTOS (STM32L152RETX microcontroller ) . in stmcubemx no any one feature to implement the any protocal like TCP/ip etc is there any possiblities to implement this protocal by using STM32L152RETx microcontrolleri...
Let know what is procedure to get PID with particular MCU part number is STM32F103, so we can used it for the mass production as our own PID. let me know how can i process it to buy PID.
Hello everyone, I am trying to use RTC in my ethernet LWIP code,but I have observed that my code hangs when I do MX_RTC_Init(); why is it so ?? Can't we use internal RTC? I can use SNTP but why does RTC hang the code?? Also my timer interrupt is no...
