Hi Team, We are working on STM32U5A9J-DK for one of our application interfaced with Octal SPI Flash.We needed to acheive RWW operation which is supported by our Flash chip and we have used OSPI1 and OSPI2 in multiplexed mode but we are controlling Ch...
I am using this dev board: NUCLEO-F411RE for developing SPI communication protocol considering it as a SLAVE device. My firmware will receive data over SPI sent by Host machine and acts on it.I have following requirement:How to transmit data packets ...
As described in RM0444I understand my virgin device (STM32G030C6T6) should to connect via UART using STM32CubeProgrammer but as shown I'm not able to establish the first transaction (byte 0x7F reception and answer)I've checked my custom board hardwar...
Hi,While working with RTC smooth calibration on a STM32G070 part, I noticed two strange things:1st strange thing: When RTC_OUT pin is only driven with the battery backup (no main power) I got 512.18 Hz; however, when the main power is restablished, t...
Hello,I was able to update F429 using boot-0 and CubeProg tool via USB. But requirement was to update without boot-0 pin. Please suggest alternatives for update from USB.Also wanted to know: I tried changing boot-0 to do DFU, using SW and HW reset bu...
Hello, I want to ask what is necessary for implementation of 32.768khz RTC XTAL to STM32F411CEU6?In AN3060 I saw in chapter 3, fig6 that external load caps are not needed because they are implemented in STM32 MCU. Then I checked STM32F411CEU6 datashe...
I am trying to figure out how to DFU a STM32G070CB, but finding the available documentation utterly useless.. According to this document : AN2606 "STM32 microcontroller system memory boot mode", my chip STM32G070 uses "Pattern 11":#1. I know what the...
Hello ST Community,I am working on an OTA (Over-The-Air) update implementation for an STM32L072 series microcontroller which has 192kb flash memory. In my setup, I have divided the flash memory into three regions: bootloader (starting at 0x08000000),...
Hello, I am having issue with running two SPI (SPI2 & SPI 3) in two streams like Stream4 and Stream7 in single DMA1. Later on i checked individually checking Stream4 for output1 and then Stream7 for output 2. I found out i am able to get the wave fo...
Hi,I am just starting to learn the STMCubeIDE debugger's capabilities. I have tested all the essential functions of the debugger on a led blink project, and after everything worked fine I moved on to an I2C code that actually requires some debugging....
