Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Hello,So I've been trying to send a raw ethernet frame using only stm32f7 hal ethernet driver without LWIP. The frame is sent, however it is always sent with a duplicate. I need to send only one frame.Is there a solution for this ?Thanks.
Excuse me.Can I change COM Port of name in keil C ?if there is no way , how to change it name ?
Hi,I have custom board for stmf401 and I try to program it in DFU mode. I set the boot0 to 1 and reset the chip but it is not recognized as DFU device. (not listed in the DfuSe).Do I miss any procedure or settings?(I have connected the PA11/PA12 pins...
Hi,I'm using STM32F407 and try to establish a USB communication. Until now the device is present in the system and is also able to send and receive bulk transfers. To test the functionality I wrote a simple example:if MCU receives a string of 5 chara...
Hello,I am attempting to use the built-in bootloader to flash code to the STM32H743 Nucleo-144 using the USART. I have tried two methods: following the flow chart in AN2606 Figure 48, and jumping directly to the bootloader, but so far neither method ...
I'm developing an STM32F429-based high-speed USB audio device that uses a Microchip USB3320 external PHY and would benefit from a DFU mode. Is there an example available anywhere for such a configuration?The default bootloader present in system memor...
hi, I am writing a custom bootloader and its only 20Kb in size, as per the STM32H7 datasheet it looks like I can't erase FLASH smaller than 128Kb, just wanted to confirm that in this case I have to waste rest of the sector data and allocate the full ...
Rev 4 of "STM32L4Rxxx and STM32L4Sxxx device errata" states that"Data FIFO gets corrupted if the write sequence to the transmit FIFO is interleaved with other OTGFS register access"and to work around it,"Ensure that the transmit FIFO write accesses c...
I'm trying to develop application using CAN driver. It looks like the STM32F1 HAL User Manual (UM1850) is outdated.The processor is STM32F103RGT6Where can I find documentation of CAN driver for 1.8.0 Cube version? Or maybe there is somewhere the upda...
Hello there,I don't know if I can call this a bug, but it shouldn't happen at all.Thing goes like this: I have a STM32G071, I enabled UCPD1 and 2, also CMSIS, USBPD library in CubeMXI generated code for SW4STM32, I write my custom board code in usbpd...
