When we use HCKL for SDRAM everything seems to work well.But we use PLL2 for SDRAM as clock source, after enter "HAL_PWR_EnterSTOPMode" mode then application free, not wakeup any more.does anyone have same issue or any hints?
Hi! I'm trying to flash a STM32L422KBT6 with STM32CubeIDE 1.13.2 and ST-LINK V2 and I keep getting this error: Error: failed to erase memoryEncountered Error when opening C:\ST\STM32CubeIDE_1.13.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externa...
I'm trying a simple blinking LED on a STM32H743VIT6 with STM32CubeIDE 1.13.2, using the clock configuration wizard. When the clock rate is set to 90MHz everything is fine, but at 480MHz the program cannot get past the SystemClock_Config() call. When ...
Hi all,I'm trying to debug a bus fault that happen on a region on ram that is not supposed to exists. MCU has 48kb of RAM, so start from 0x20000000 to 0x2000C000, but i'm able to write 0xFF from 0x2000C000 to 0x20010000.. why??I can see also some dat...
Hello,I'm currently working on a system bootloader using an STM32L4P5VGTx board. During this process, the board entered an unknown state and doesn't seem to recover even after a reset.I also attempted to use the Cube Programmer tool to load a bin fil...
Hi,I'm trying to improve the accuracy of RTC. For that, I use the AN2604 witch describe this.But, when I activate the calibration output of RTC at 512Hz, I have only 496Hz at the output. (AsynchPrediv =127). I tried this simple code to the nucleo-L47...
Imported an example code of CAN loopback on STM32F446RE board, Please guide me to check the signal in DSO(hantek Software), I do not have a CAN analyzer please help me to get the signal in digital oscilloscope.
Can't post screenshots.RM0401 rev3 ('F410), RCC_APB2ENR contains EXTIEN. There is no such bit in any other STM32, EXTI is unconditionally enabled everywhere else. There is no respective reset bit in RCC_APB2RSTR. Is this bit real?in the same RM0401 r...
Posted on November 27, 2015 at 10:52When I try to target->connect in ST Link Utility I have an error ''unknown device'' with disco L4, disco F7 and nucleo L4. With nucleo L0, the connection is good, but I have the message ''Device family : unknown d...
TL;DR. What are the limiting factors for incoming clock speed for an SPI peripheral operating in slave mode?I'm using the STM32U575 MCU with a few peripherals, and am clocking it down to 16MHz for SYSCLK and all related peripherals. I'm generating a...
