STM32H757 - Bootloader in CM4
Hi all,is it possible to write a bootloader which sits at the beginning of the CM4 memory block and updates the CM7 as well as the CM4 (userapp sits in the memory area of the CM4 behind the bootloader)?I imagine it like this: The configuration bit th...
Resolved! STM32F722ZE Error: Mass erase operation failed. Please verify flash protection. STM32F722ZE
I debuged my software on the STM32F722ZE, when I suddenly lost connection to it. I tried to connect to it with ST-Link V2 and Segger J-Link. Error message from J-Link commander is: Can not attach to CPU. Trying connect under reset. Connecting to CPU ...
Stlink 2-1 Connection problem.
I am going crazy! I am working with an STM32f745 and I am having SWD connection issues. I have a STlink 2-1 jumpered using the header connection from it over to my board Now, a interesting thing is happening when I probe the SWDCLK and SWIDIO li...
DMX decoder using STM32 H7
Hello everyone,I am trying to receiver a DMX frame using STM32 UART interrupts. I'm trying to receive the data byte-by-byte using a state machine logic. The problem I am facing here is that none of the debug LED code to toggles the LEDs when the prog...
Resolved! STM32 dual channel ADC
I am trying to read ADC from two channels without using DMA. For that I use this code: /* USER CODE BEGIN 0 */uint16_t ADC_VAL[2];void ADC_Select_CH1(void){ ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Channel = ADC_CHANNEL_0; sConfig.Rank...
I2S and SDRAM
Hi all,I am using an STM32F429 discovery board to develop a DSP platform for making some sound effects. I have I2S streaming and passing through, and I have SDRAM configured where I can talk to it and even transfer my buffers on and off it.Where I am...
NUCLEO-F103RB startup with the ST-Link disconnected adds delay
The below oscilloscope capture appears to show that disconnecting the ST-Link from the Windows laptop adds 80 ms to the NUCLEO startup, until the first UART packet is sent. If that is correct, what can cause this delay?Thank you in advance for your f...
NUCLEO-F767ZI as USB host and NUCLEO-F103RB via ST-Link (VCP) and UART as USB Client
Hi,I'm trying to set up a USB host using a Nucleo144-F767ZI, which should exchange data with a Nucleo64-F103RB through USB. Since the Nucleo64 doesn't have a USB interface for the F103, I want to utilize the VCP (Virtual Com Port) of the ST-Link on t...
Resolved! STM32U5A9 OctoSPI memory mapped (read only) with NOR FLASH triggers hard fault on first access.
I am trying to bring up the MX25UM51245G NOR Flash connected to OctoSPI 1 on a STM32U5xx development board. I have implemented most of the actions specified in AN5050 to set up this NOR Flash.Since my use case does NOT require the ability to have the...
SPI Receive more characters than sent
I try to setup a SPI COmmunication to do some "cross-communication" for Safety Reasons.So in my test setup, i read characters from UART, send them via SPI to the Slave, the Slave logs them via UART and ackknowledges them through sending an "39".Sendi...
