Resolved! RM0433 and devices header disagree on BDMA registers

RM0433 talks about a BDMA_CM1ARx register and lists it in the register maps. The description in rm0433 for BDMA_CM1ARx seems to be tha same as for BDMA_CM0ARx. The device headers only talks about the CMAR register.Please clarify.

brightness of the led connected to the stm ic pin reduces.

Hai I have a simple design.I am using STM32F051R4T6TR.I just connected a led such that the led sinks the 20mA current when the led turns on.i happen to notice that each time i switch on my board the brightness of my led is getting reduced.this happen...

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.
