Resolved! STM32L4P5xx system bootloader: is RAM3 valid SRAM for the stack pointer?
Does the system memory bootloader for the STM32L4P5xx consider RAM3 as valid SRAM for the stack pointer?After programming bank 2, and then setting BFB2, The device will not boot into bank 2. The linker has the top of the stack at RAM3. The value wr...
STM32F205RBT7: Suggestions needed for reliable IWDG behavior
Hello ST Community,I’m working on a project using the STM32F205RBT7 and planning to integrate the Independent Watchdog (IWDG) for system recovery. However, I’ve encountered significant timing inconsistencies across multiple boards (tested on at least...
Resolved! STM32L4S5 write data to 2MB flash memory (STM32CubeIDE)
I am trying to write to the flash memory of the STM32L4S5QIIX microcontroller on the EVAL-ADIN1110EBZ development board. I have also tried similar code on an STM32L4S5VITX microcontroller on a custom circuit board.Short example code:uint32_t flash_me...
I2C_frequency configuration
Hi,I would like to configure the I2C frequency based on the input clock frequency. Is there a specific formula to calculate the I2C timing values? Also, I would like to know whether this formula is applicable to all STM32 microcontrollers, or if it v...
Issues with interrupt priority handling
Hello,i have configured a timer interrupt an it seems like that interrupt preempt another adc interrupt. I configured the timer interrupt like that: NVIC_SetPriority(TIM1_BRK_IRQn, 2U); NVIC_SetPriority(TIM1_UP_IRQn, 2U); and the adc interrupt like t...

Resolved! STM32L011 bootloader cannot read SRAM
I have an STM32L011 on a board I am developing.I can enter the bootloader no problem, as per AN2606/AN3155. I am using USART2, 57600 baud.I can program FLASH/erase FLASH/read FLASH - all works as expected.I note that the bootloader reserves 2048byte...
Resolved! Project not picking up RAM section from linker file
I am working with a dual core STM32H755 and attempting to create a shared memory location for the two cores to access. I am attempting to do this by modifying the linker script. I have added the following lines to the M7 core linker script, in the S...
硬件不变的情况下，SPI+DMA 循环模式主机接收 采集电压异常，Normal模式却正常
用SPI+DMA驱动AD4001，用片选信号代替 CONV，采集一个正弦信号。Normalnormal正常，循环模式却不对，求大佬解答！！Normal模式下，每次在 HAL_SPI_RxCpltCallback 函数里面重新启动数据正常，能看到正弦变化规律 循环模式下数据就不对了，采集的同样一个交流信号，我在半传输完成回调里面查看，按道理后半部分的数据应该是正常的正弦变化才对，实际却不是，但是去采集直流时又是正常的。 ...
