Resolved! Hard fault not occurring? Trying to create intentional hard fault
this may be little weird asking to the big guys. But I'm learning how to produce hard fault so as to debug it again using registers. Also I tried initializing np with NULL. but still no success/* USER CODE BEGIN Header */ /** **********************...
Resolved! Code running slow on M4 CPU of a STM32H747 DISCO board
I'm using a STM32H747 DISCO boad and I just want to use the M4 CPU. When start, the M7 configs the Clock and does nothing since then. There is only a simple case running on the M4 CPU. The case takes 200ms on M4 while it took only 20ms on a Risc-v@30...
STM32 crypto on microSD with PC deciphering
I am working on STM32u585. The STM receives data on SPI bus, cipher data and store cipher data on microSD.Then the microSD is read on PC and data has to be deciphered for human reading.What is the best mean to perform this ciphering process ? Can the...
Need to send ASCII and then HEX
I am trying to send commands to a Netion display which needs ASCII and then termination of 3 hex 0xFFs.I tried this: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET); char Cdata[11] = "bt6.val=[1]"; HAL_UART_Transmit(&huart1, Cdata...
Output of Voltage reference buffer does not match expected value.
I set up the VREFBUF (using CubeMx) to use the internal voltage reference, with a SCALE of 2.048V. When i probe the Vref pin i see a voltage of around 2.2-2.3V, it changes slightly after ever power reset. It is a custom board with a G061c8 micro. The...

Resolved! Understanding the SPI Peripheral when accepting and sending data.
I have my STM32F407VE successfully configured as a slave device. Goal is to emulate a PlayStation 2 controller.Where I am at right now is that I am trying to send a specific order of bytes so I can be sure that before I read and act on the command by...
Resolved! Trouble to locate data section in flash (STM32F207)
Hi,I attempt to locate information about the firmware in flash. To do so, the data are stored in a dedicated section (called CONTROL_UNIT_SECTION):/** @brief Definition of the firmware info. */ typedef struct firmware_info_t { uint8_t id; ...
Cache coherency issues when reading DMA buffer from ADC
Hello,I face serveral data coherency issues on my dma buffer which is used to place the values of serveral ADC channels into it. This is executed on M7 contextJust as a reference, I have a dummy project without any MPU configuration and data cache is...
