Hello,I have an STM32H743 on a custom application PCB and I need to use the IWDG as well as the standby mode to save precious battery current.I have noticed the following strange behavior:1 - I mass erase the STM32H743 using STM32CubeProgrammer2 - I ...

Hello, I have written a Flash bootloader for the STM32H743 for our custom application PCB. In a nutshell, the flash bootloader check an external flash memory IC with SPI on the custom application PCB if there is a new image to be flash and do it if i...

Hello,I am evaluating the STM32H723 with the NUCLEO-H723ZG board and I need to use the standby mode with GPIO wake-up.On the board, I have added a 10k pull-down resistor between pin PA0 (connector CN10 pin 29) and GND. I also have wire that I use to ...

Hello,I'm trying to communicate with the USB FS CDC on my NUCLEO-H723ZG while using FreeRTOS and the device doesn't enumerate properly. I am using the current up-to-date software pack for STM32H7 -> 1.11.2I use the CubeMX starting project with the NU...

Hi Sarra, Sadly, it doesn't work calling NVIC_SystemReset(). While the MCU reset and restart the program, the IWDG still wakes up the STM32H7 when calling HAL_PWR_EnterSTANDBYMode().I really need to do a system reset for the low power function to wor...

Hello,It works properly now! I can reliably flash application of more than 900 kB!Wow I feel so dumb about this mistake... I should have read the documentation more carefully... Thank a lot for the quick response Pavel A. and TDK !

Yes it is true that I didn't reset the "counter" variable. My goal is that the reset on the Exit of Standby mode reset the counter to 0 as the RAM is wiped out.I found a workaround solution... I went in the examples_LL folder in ST examples for the S...

Hello SofLit,The CDC_Transmit_HS I called in the while(1) is a leftover function call when I first started the project without FreeRTOS to check functionality. My bad, I should have removed it when I added FreeRTOS in CubeMX. However, this function i...
