For our device, we are using STM32H750 IC. in some 100 PCBs manufactured at our company, in 1 or 2 PCBs we cannot program the blank MCU and get this warning in STM32CubeProgrammer. "Warning: The core is locked up"What can be the issue? any specific p...

Hi, we are using STM32H743VIT6 IC for past 3 to 4 years. but from January, none of the newly bought IC is getting programmed via DFUSE. the IC gets connected, erase cycle starts reaches upto 49% and then nothing happens. only the timer is incremented...

HI, we are working on STM32H750. in our program, we need to store 5 bytes in the internal flash. this data will be read everytime the device is powered on. the data will be changed whenever the settings are changed by the user. i.e. once in a while.M...

Hi, I am using STM32H753VI on my own board. I was trying to programme the chip using SDCard through IAP. the program works perfectly till it erase bank1(from 0x08020000 to end of sector7 of bank1) and whole bank2.then copies the bin file to flash. ev...

Hi Simosilva, Programming worked fine. Thanks for the help. Now my next code isjumpadd = *(__IO uint 32_t*) (FLASH_USER_START_ADDRESS+4);Jump = (pFunction) jumped;__set_MSP(*(__IO uint32_t*) FLASH_USER_START_ADDRESS);Jump();Right?The binary file i...

Hi Simosilva,The erase function worked fine. Do we have a similar function for programming also? Because it gives the same error (flash_waitforlastoperation) for HAL_FLASH_Program(Flash_TYPEPROGRAM_FLASHWORD, address, 32 bit data);

Hi,My bootloader program is at 0x8000000. And I am erasing the memory from 0x8020000.The program does not work even without the debugger. It stucks at the same point, this I can assume because I have toggled the LED before and after the erase funct...

Hi,the chip is blank, and the same program runs well on other similar PCBs. so power supply misconfiguration may not be the cause.
