Hi, I want to use OTA in stm32h743, for that I need to switch between two bank after flash write, as per reference manual//HAL_FLASH_OB_Lock(); HAL_FLASH_OB_Unlock(); /* Set OPTSTRT Bit */ SET_BIT(FLASH->OPTSR_PRG, FLASH_OPTCR_SWAP_BANK); /* Wa...
The calibration at a DIV256 works most of the time but some MCU must be calibrated with a DIV1 otherwhise I get an offset of zero. We use VREFBUFF as reference. We try to swap an MCU with good result (DIV256 worked). One MCU calibrated but with error...
Dear colleagues,I woild like to ask you help me with may issue below:Why do I lose data when writing flash memory and an error occurs my code in the attachment.Code seems good, but I am sure that I loose something.In memory loosed letters "llo" from ...

I am using the B-U585I-IOT02A discovery kit with the STM32U585AI chip. Attempting to set the system clock value in STM Cube to anything that would result in voltage scaling above PWR_REGULATOR_VOLTAGE_SCALE4 results in a timeout and thus failure in t...
Hello,A product I'm working on requires communicating with an FPGA over an 8 bit data + 24 bit address bus.To support a legacy design with the least possible changes I need the bus to toggle at 43.75 MHz.All I need is single (non-burst) address acces...
im using pc8 as a reset pin and ive check it with a logic analyzer and wen its initalized it drops low then goes back to high before im calling my function to drop it low btw im using saleae logic 2 void reset_pin_init(void){ //PC8 RCC->AHB1ENR |= ...
In my code i first setup the sim7600 using blocking mode and later switch to dma. But in blocking mode I'm having trouble receiving data over uart. Using a nucleo it sometimes works very reliably and other times doesn't work at all or it only receive...
