IAP over GSM: UART and Flash programming
Posted on January 07, 2016 at 16:29 Hi, I'm developing an IAP application for firmware upgrade over GSM network. I've a SIM800H module connected to STM32 over UART interface and I'm able to establish GSM connection, setup HTTP GET request an...
Exact wakeup reason from standy mode (STM32F429): RTC vs WKUP pin
Hi, I am looking for a way to determine what caused a wakeup from standby mode, in my case the options are RTC or the WKUP pin (and if you have multiple, which pin). In my case I only have one WKUP pin, so I could check the RTC and conclude if it was...
MCU selector misses Voltage reference buffer
Hello,looking for a STM32 in small package with pins where optical solder inspection is possible, I hoped that the MCU Selector from STCube would offer me a checkbox to select devices with Voltage reference buffer output. I did not find that checkou...
how dose the PC run to startup.s when the mcu reset
Hi，dear enginner： i want to know how the PC run to startup.s when mcu reset？ The Definitive Guide to the ARM Cortex-M3 says address 0x00000000 is MSP‘，address 0x00000004 is ResetVector. But when I look at STM32F767, I find that 0x00000000 and 0x4 ...

When enable USBHS internal IP DMA, STM32F746 discovery board fail to enumerate.
Posted on February 08, 2017 at 20:27I use STM32CubeMX to generate STM32F46 discovery board project, just enable 'USBHS internal IP DMA', Choose CDC class, show as the attached picture 01, when I compile and run the firmware, connect the USB HS port...
I am using STM32F401RB controller. Iam using external oscillator of 8MHz. The HSE and PLL mode is used. When i try to run the program, it hangs and no output. When I configure the internal oscillator it works fine. Please let me the solution for this.
I have called the three functions as: HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); HAL_GPIO_WritePin(GPIOC, GPIO_PIN_6, GPIO_PIN_SET);when debugging it either jumps to hard fault or hangs.The SystemClock_Config() is as follows:void Syste...
Do I need to configure my flash memory interface register (FLASH_ACR)?
The Keil example 'EXTI project' is a simple program for the STM32F103RBT6 MCU. Here, the following statements are executed:#define __EFI_ACR_Val 0x00000012 /*---------------------------------------------------------------------------- STM32 em...
