Hello.There is a board with 2 stm32 MCU, one of them is stm32l452. I need to upload a firmware to stm32l452 using system boot. When it starts in system boot mode, second MCU sends 0x7F waiting acknowlenge byte (0x79) but there isn't a responce. After...
Will a voltage divider and a Zener diode pretty much suffice or will galvanic separation be necessary? Does anyone know/have an out-of-the-box solution?Thanks,Mike

Hi!I'm trying to save values in the FLASH memory, but the values don't are saved. I've implemented erase command in order to preform flash_program command. I'm using a NUCLEO64 - STM32F303RE...if(HAL_FLASH_Unlock() != HAL_OK) { debugPrintln(&hu...
I recently switched from DMA to IT for receiving commands via SPI. Now I'm noticing that commands are being received and processed correctly, but HAL_SPI_RxHalfCpltCallback() is no longer being called. A lot has changed in my program since then, but ...
I wanted to program custom stm32l496retg MCU Board from stm32l496zg nucleo board .i used sw4stm32 IDE to program the MCU custom Board.Removed two jumpers of CN4.But getting Wrong device detected Open On-Chip Debugger 0.10.0+dev-00021-g524e8c8 (2019...
Hi Team,I am using the stm32h745-dico board. I am trying to trasmitt and receive the data using DMA through the UART1 from the PB6 & PB7 . Is there any specific streams for Rx and Tx for particular UART.when I am working with the UART3 I used strea...
Hello,I'm curious if there is any way how to load correctly linked elf file into the SDRAM of st32h757i-eval board. By correctly linked elf I mean everything is either linked into SDRAM or to some of the SRAMs. E.g. readelf -S of the elf looks:There ...
Dear ST Team, could you please update this section with correct information?There is incorrect text description or figure in RM0454 Rev 2 in section 14.10 (VBAT).Text: "...converted digital value is half the VBATvoltage."Figure: VBAT/3.
