STM32H755 : Can both M7 and M4 access both internal flash banks in parallel?
Can M4 write to part of Bank 1 when M7 code is running from Bank 1? Idea is to define apartition at the end of Bank 1 and M4 write to it while M7 reads from it. I know thisneeds some tweaking of the dts to assign both Bank 1 and Bank 2 to M4 as below...
TIMER SYSCHRONISATION
I am using STM32F446RE microcontroller and using MATLAB to develop the logic. Upon launching StmCubeMx, I have kept the clock frequency as 90MHz and 10% duty cycle for TIM1, TIM2, TIM3. So, it gives same output frequency of the pulses (PWM_Output.png...
Resolved! Help with load & Executing Code into Stm32 mcu Ram
I have both STM32F1038T6 and STM32F401CC. I have been trying to get a code to run from ram for days now. Im using arduino ide with stm32duino. i first create a buffer in ram with malloc then copy the code to the buffer using memcpy. The code is in ...
Cannot access memory
Hi, I am having problem with string copy strncpy(). I am getting error message "Cannot access memory at address 0x31203a6e" static char *DataBuffer[30] = {0}; for(char *str =strtok((char*)recdata, "\n\n"); str; str = strtok(NULL, "\n\n")) { strncp...
STM32L476
Dear Sir,I use NUCLEO-L476 , Once I connect it to usba new window pop up like with the Caption NODE_L476RG .Erasing the CPU still the window pop up.What should I do to make this board to act as plain PCB
Resolved! About QFN package for STM32U59xx
Hi,Why there are no QFN packages for STM32U59 series? Will it be added in the future?Thanks.
Resolved! stm32f407 Disc and external stlink problem
Hi everyone I'm trying to use external debugger with my stm32 disc1 board. The problem is if i only connect the stlink and my board i can't debug it, but if I power the board with another usb port i can access it.So my question is why do i have to po...
STM32F437 External Memory Interface
Posted on April 13, 2015 at 14:00In one of our embedded systems we use a MR256A08B MRAM in conjunction with a STM32F437 microcontroller. Sometimes (increasing with temperature) we are observing the problem that we cannot write to discrete bits of th...
Resolved! Error: Interlacing the process
I am using STM32H7 and using the M4 core to output GPIO to control peripherals.I share data between the two cores using the share memory protocol.On the M4 core, I have turned off all interrupts and only control GPIO, but when measured, there is stil...
