Hi all,I'm building a discharger using my STM F446RE, such that it's RTC registers are used to store data that'll be loaded to set parameters in my code every time the discharger is plugged into the power. Just to clarify - I'm NOT using the RTC as a...
Hello, we are facing some problem entering DFU mode from application code on our custom boards equipped with STM32H7B3 with bootloader release 0x92. On contrary, everything works fine with same board equipped with STM32H7B3 bootloader release 0x91. ...
Hi, I am planning to use the external serial QSPI flash interface with STM32H753. Flash part number is MT25QL256ABA1EW7-0SIT or IS25LP064D-JKLE-TR. Operating voltage 3.3V at frequency of 80MHz DDR. Can you please let me know will there be any concern...
Hi ST community,I'm using the STM32F303ZE in a design and need to ensure that the clocks for various peripherals stay within acceptable tolerances (in ppm or %) — especially across the full temperature range (–40°C to +105°C). I plan to use an extern...
I am using the startup file in Keil. However, when I run the simulation in the debugger, my system clock (SYSCLK) is not 72 MHz, even though I have confirmed that HSE_VALUE is set to 8 MHz.Can someone help me figure out why the SYSCLK is incorrect du...
Does the STM32U5G9ZJT6Q SoC not support SDMMC2?
Hi I'm implementing Openbootloader to my project, using an STM32H743, and is having a hard time finding the correct start addresses and size for "Option bytes registers". This is needed to in the "openbootloader_conf.h" file in the Openbootloader mid...
I want to set up 100MHz for SDRAM.STM32CubeIDE version 1.18.1 has the following options for SDRAM clock:The selected board is the STM32H743IITx. RM0433 Rev 8 states that:I'm not sure HCLK and fmc_ker_ck are the same thing.If I have my FMC clock set u...
I followed the GPDMA tutorial here:https://www.youtube.com/watch?v=jKOhRfb3gvkand configured everything as shown. The workshop was on a U575 but I would assume it's the same configuration for the U5A5? I'm using the Nucleo-U5A5ZJ-Q. I'm unable to ...
Hello! I'm working with FreeRTOS for the first time and am getting a HardFault during the call HAL_NVIC_EnableIRQ(TIM4_IRQn); call inside of HAL_InitTick(); from HAL_Init();I am currently testing with a Nucleo board with MCU STM32F401RET6U and have c...
