Master is a STM32H757, slave is a LSM6DSO ( accelero + gyro ). I have a SPI link inbetween. The "int2" pin on the LSM6 rise up when data are readable in registers.This pin is connected on EXTI2 on STM32.Register read is auto incremental on LSM6.I nee...

Hi, I dont know how this happened, but my Eval board STM32H757 can not go after :SystemClock_Config() ==> HAL_PWREx_ConfigSupply() ==> while (__HAL_PWR_GET_FLAG (PWR_FLAG_ACTVOSRDY) == 0U)The progam stay in the while loop : while (__HAL_PWR_GET_FLAG ...

Hi, I am curently working on the STM32H747. I need to have the CM7 booting while the CM4 is not. Then after, the CM4 BOOT is triggered by the CM7.Using STM32 cube programmer, I am able to disable the BCM4 bit of the SYSCFG_UR1 register.The required s...

Hello everybody, Here is my needI am using STM32F469NI, and I need to generate a PWM signal using timer1. I need to generate a burst of 4 pwm cycles. Each cycle must have a specific duty cycle value. I already did that using DMA that load each duty c...

Hi, I am working with Byann.1 on this board. One point that I can add on this issue is that when the smps output voltage is at a steady 400mV, a short voltage pulse to 1.2V on VFB_SMPS ( using external LDO ) will make the smps output voltage to stay ...

I finaly made a custom HAL function based on HAL_SPI_Receive_DMA : here is the prototype :HAL_StatusTypeDef HAL_SPI_TransmitReceive_DMA_Custom(SPI_HandleTypeDef *hspi, uint8_t *pTxData, uint8_t *pRxData, uint16_t SizeTx, uint16_t SizeRx);in the funct...

Thank you, it did the job. Now registers are SMPS = 1 and LDOEN =0. The code is running well.

I also did the dead lock recover procedure that didn't changed CR3 register values, so did not solved the problem.

Question 2 : When the Go command is issued from the master, ( set pointer to start adress of loaded code in slave), what is the core that will start from this adress ( CM4 or CM7 ) ? I dont understant how it is managed.thank you

How to continuousely loop read few register on SPI slave device, using DMA, when dummy bytes used to generate clock must be specified ( slave register adress) ?

STM32H757 Eval Board locked in illegal power configuration. How to unlock ?

Hi,I am using the STM32H757(master) to load code into flash of another STM32H757(slave). The slave is in bootloader mode ( SPI ). Question 1: Does somebody has a driver for the master side to read/write into slave, especialy option bytes? Thank you
