Hi I am trying to write a code using STM32f103r8t6, i have installed IAR for Arm v8.40.1 i started to create a project but i could not find any library files. and then by downloading an example file i got the library files as i tried to complile i m ...
STM32F767ZI Nucleo board works from Flash on ITCM slower if ART is on
I detected that ART accelerator and prefetch is not enabled. Why for loop gets slower if if I switch both on ? /* USER CODE BEGIN SysInit */ #if defined(FLASH_ART_ON) // enable ART for Flash (x8 Booster) int FLASH_ACR_REG=0; volatile unsign...
Resolved! LED blinks only in debug mode
Hi!I have a basic code - blinking LED code which uses onboard LED (PC13). The problem is that it doesn't toggle at all, it just stay switched on and doesn't go off after delay. I've tested that code in debug mode and everything worked fine, it toggl...
How to speed up IRQ times at STM32F7xxx ?
CPU 210MHzIf you run IRQ code from flash you have about 5 times more cpu cycles as needed (7WS)if you switch on ART accelerater and prefetch: for loop gets slower no influence on IRQ latencyyou could not run code from internal SRAM because of missin...
STM32F767ZI could not remapped to internal SRAM
Hi folks, I have tried to run my complete program out of internal SRAM to speed up the IRQsbut if I come to svc 0 it failsprvPortStartFirstTask: 20005ee0: ldr r0, [pc, #32] ; (0x20005f04) 20005ee2: ldr r0, [r0, #0] 20005ee4: ldr r...
STM32F765IIK6 Reflow Problems
We are using STM32F765IIK6 176 pin 10x10 0.6mm UFBGA, die rev "Z". Whilst processing these through SMT solder reflow (using an 8 zone forced air convection oven) we had a number of these devices failing, due to the substrate of the BGA package dishin...
production ready STM32 boards
Hi,Does anyone know if there are any companies out there that sell production ready stm32 hardware boards. I appreciated there would be a lot of variations regarding io etc.. but i just wondered if it was a "thing" or if the only board are typically ...
Resolved! STM32L431 can't enter STOP2 mode
I'm trying to enter STOP2 mode to save energy but the MCU get stuck in the function HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI). I have cleared all EXTI pending flags and RTC flags, and disable all five wake up pins. The MCU is supposed to wake up vi...
