Execution of code in SRAM of STM32F405

Hi, I am using STM32F405.I use the Flash Sector as follows. - Sector 0: IAP - Secotr 2: Data Save - Sector 5: Main ApplicationMain Save the data in APP. And Main_APP erases Sector2 before writing the data.While erasing Sector2 from Main_APP, I notice...

Nucleo F767ZI - system freeze upon UART ORE interrupt

Hi,My system (MCU) gets into a state where I can't debug it when i get a UART interrupt due to ORE.I even tried placing breakpoints at the places where ORE is captured in the IRQ handler - but the debugger didnt stop and I lost the connection to the ...

I am working with an STM32F405. Planning to use Segger J-link probe and J-scope combination to visualize RAM variables over the JTAG/SWD/SWO interface. does anyone know what is the maximum sampling frequency I can achieve with the STM32F405?

Segger quotes the J-link Ultra+'s target interface speed at 50MHz and an "unlimited sampling bandwidth, limited by the bandwidth of the debug interface"... Ideally I would like to plot 4 floats at atleast 10kHz sampling rate.

How to config SYS_WKUP3 for STM32L4 MCU Standby mode?

Hi,I am setting up STM32L4 for standby mode. From Cube and NUCLEO-L496ZG\Examples\PWR\PWR_SLEEP\Src the GPIO pin is PE6.However I don't see any Cube generated code to init this pin. Neither in example code.Should I init the PE6 as GPIO input pin?Thx ...

Encoder mode and rotary encoder

Posted on April 03, 2018 at 11:10 Hi, I'm using STM32F072RB and a rotary encoder (with 30 dentet) connected to TIM2 in 'encoder mode' and I can see in TIM2->CNT that it is actually counting correctly. I trying to get an interrupt on each detent...
