Hi all,I am using stm32l486 MCU and trying to use stmcube internal flash example code. As i see we have API "HAL_FLASH_Program" to program word or double word. Is it possible to write byte data by doing type casting and increasing the address by 1?Co...

Hi everyone,I am using stm32l4xx UART driver. I can read and write data. I am using HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint32_t Timeout)HAL_StatusTypeDef HAL_UART_Receive(UART_HandleTypeDef *...

Hi @Community member :Thanks for the reply.Can I combined the bytes and write as a word or double word as below:data32 = wr_buff[3] | (wr_buff[2]<<8) | (wr_buff[1]<<16) | (wr_buff[0]<<24);HAL_FLASH_Program(TYPEPROGRAM_WORD, Address, data32);Thanks,J...

Hi , I am able to fix the issue by calling QSPI Abort API. Now able to read the data in memory mapped mode.
