I am using STM32L152R8T6-A MCU. I use 3 UARTs in my project. UART buadrates are 9600 and 115200 bps.Initially I set the clock source to HSI (16MHz) and everything worked fine. But then I decided to change the clock source to MSI (2.097 or 4.194 MHz)....
I have an STM32L152R8T6-A MCU. A new firmware is downloaded over HTTP (as a .bin file) and is stored in an external flash memory. After that a bootloader copies the new firmware into MCU flash (address 0x8000000) and resets the micro.Everything is OK...
Hi All,I am trying to program a STM32L152R8 MCU with stm32cubeIDE v1.4. The MCU is not brand-new and is soldered on a board. I want to change its firmware. While debugging with ST-Link Debugger I encounter the following error:-------Memory Programmin...
Hi there,I am using STM32CubeIDE 1.3.0 with STM32L152x MCUs. When using ST-Link GDB Server, STM32CubeIDE insists on updating Stlink firmware to the latest version (Now is V2.36.S7). After that I get the following errors:ST-LINK SN : 49FF7606837056521...
As mentioned in STM32L152R reference manual, before entering the STOP mode, all EXTI, peripherals and RTC interrupt pending bits should be reset, otherwise the stop mode entrance is ignored. Is there any way to perform this at once?
I didn't use any interrupt. I receive the data using simple polling methid, i.e. : HAL_UART_Receive(), so no processing is done during the data receive.
